Chapter 2 | The Learning Process
The Learning Process
The First Flight
When Beverly (student) enthusiastically presents herself for her ﬁrst day of ﬂight instruction, Bill, her Certiﬁcated Flight Instructor (CFI), decides to spend some time in the classroom. Beverly knows a lot of facts about ﬂying and shares her knowledge with Bill, but when he asks questions to test her understanding of the facts, she cannot answer them. During their ﬁrst ﬂight, Bill discovers Beverly has mastered a few basic skills, but her performance is awkward, as if she were working from a list of memorized steps.
In the early stages of ﬂight training, Beverly focuses all her attention on performing each skill. If Bill asks her a question or to perform two tasks at once, she loses her place and must restart. As she ﬂies, she makes errors. When she catches herself making an error, she becomes visibly frustrated. Then sometimes she does not notice an error and keeps moving ahead as if nothing were amiss. Since she is a beginner, Bill is patient.
The Check Ride
Months later, Bill is helping Beverly prepare for her practical test. Remembering her ﬁrst days of instruction, Bill feels as if he were working with a different person. The breadth and depth of her classroom knowledge has grown. Beverly does not simply reiterate facts—she applies her knowledge to solve the problems Bill gives her. In addition to the required knowledge listed in the Practical Test Standards (PTS), she also knows about her local environment, such as the nuances of local weather patterns.
In the aircraft, once awkward and tentative actions are now performed with a steady hand and conﬁdence. Skills she struggled to learn in the past have become second nature. When asked to do several things simultaneously, she performs well. When Bill interrupts her, she mentally bookmarks where she is, contends with the interruption, and then returns to the task at hand. She still makes errors, but they are small ones that she notices and corrects right away. She still gets frustrated when she makes an error, but she takes a deep breath, and continues on her way. She makes ﬂying look easy, and Bill is conﬁdent that tomorrow’s meeting with the examiner will go well.
Discussion of First Flight and Check Ride
Between Beverly’s ﬁrst day of training and the day before her practical test, she has undergone some remarkable changes:
She has developed a collection of memorized facts into an in-depth understanding of how to ﬂy and learned to apply this knowledge to problem-solving and decision-making.
Skills once performed awkwardly and deliberately are now performed smoothly and efﬁciently.
She comfortably performs several tasks at once, deals with distractions and interruptions, and maintains her focus in demanding situations. Knowledge and skills are now orchestrated.
She still makes errors, but they are less frequent, smaller in magnitude, and she quickly identiﬁes and corrects them.
Her motivation and enthusiasm remain as high as they were on the ﬁrst day of training.
She displays proficiency in all areas now: those at which she naturally excels as well as those she struggled to master in the past.
She deals with psychological obstacles, such as frustration, that initially got in the way of her learning.
She recognizes the importance of regular study and practice.
This scenario illustrates the goal of an aviation instructor: to teach each student in such a way that he or she will become a competent pilot or aviation maintenance technician (AMT). In order to take a pilot or AMT from memorized facts to higher levels of knowledge and skill that include the ability to exercise judgment and solve problems, an instructor needs to know how people learn. Designed as a basic guide in applied educational psychology, this chapter addresses how people learn.
What Is Learning?
Learning can be deﬁned in many ways:
A change in the behavior of the learner as a result of experience. The behavior can be physical and overt, or it can be intellectual or attitudinal.
The process by which experience brings about a relatively permanent change in behavior.
The change in behavior that results from experience and practice.
Gaining knowledge or skills, or developing a behavior, through study, instruction, or experience.
The process of acquiring knowledge or skill through study, experience, or teaching. It depends on experience and leads to long-term changes in behavior potential. Behavior potential describes the possible behavior of an individual (not actual behavior) in a given situation in order to achieve a goal.
A relatively permanent change in cognition, resulting from experience and directly inﬂuencing behavior.
The effective instructor understands the subject being taught, the student, the learning process, and the interrelationships that exist. An effective instructor also realizes learning is a complex procedure and assists each student in reaching the learning outcomes while helping the student build self-esteem and conﬁdence. [Figure 2-1]
Figure 2-1. An effective instructor understands the characteristics of learning and assists students accordingly.
The Framework for Learning
Research into how people learn gained momentum with the Swiss scientist and psychologist Jean Piaget, who studied the intellectual development of children in the early twentieth century. [Figure 2-2] His studies influenced others to research not only how people learn, but also the best ways to teach them, leading eventually to the establishment of the ﬁeld of educational psychology.
Figure 2-2. Jean Piaget, Swiss scientist and psychologist.
Learning theory is a body of principles advocated by psychologists and educators to explain how people acquire skills, knowledge, and attitudes. Various branches of learning theory are used in formal training programs to improve and accelerate the learning process. Key concepts such as desired learning outcomes, objectives of the training, and depth of training also apply. When properly integrated, learning principles can be useful to aviation instructors and developers of instructional programs for both pilots and AMTs.
Many psychologists and educators have attempted to explain how people learn. While variations abound, modern learning theories grew out of two concepts of how people learn: behaviorism and cognitive theory.
Behaviorism is a school of psychology that explains animal and human behavior entirely in terms of observable and measurable responses to stimuli. Behaviorism was introduced in the early twentieth century and its followers believed all human behavior is conditioned more or less by events in the environment. Thus, human behavior can be predicted based on past rewards and punishments. Classic behaviorist theory in education stressed a system of rewards and punishment or the “carrot and stick” approach to learning. In modern education circles, behaviorism stresses the importance of having a particular form of behavior positively reinforced by someone (other than the learner) who shapes or controls what is learned rather than no reinforcement or punishment. In aviation training, the instructor provides the reinforcement.
Although the popular therapeutic system of behavior modiﬁcation has emerged from this theory, behaviorism is now used more to break unwanted behaviors, such as smoking, than in teaching. The popularity of behaviorism has waned due to research that indicates learning is a much more complex process than a response to stimuli. Humans, far from being passive products of experience, are always actively interacting with the environment.
Cognitive theory focuses on what is going on inside the mind. It is more concerned with cognition (the process of thinking and learning)—knowing, perceiving, problem-solving, decision-making, awareness, and related intellectual activities—than with stimulus and response. Learning is not just a change in behavior; it is a change in the way a learner thinks, understands, or feels. Theories based on cognition are concerned with the mental events of the learner. Much of the recent psychological thinking and experimentation in education includes some facets of the cognitive theory.
Early theories of cognitive learning were established by psychologists and educators such as John Dewey, Jean Piaget, Benjamin Bloom, and Jerome Bruner. [Figure 2-3] Over the past century, there have been many interpretations of the increasingly large amount of research data dealing with cognitive theories. This has led to many different models for learning as well as catch phrases.
Figure 2-3. Psychologists and educators who established the early theories of cognitive learning.
For example, educator, psychologist, and philosopher, John Dewey introduced the concept “reﬂective thought” in a 1910 book designed for teachers. Dewey believed learning improves to the degree that it arises out of the process of reﬂection. Over the years, terminology describing reﬂection has spawned a host of synonyms, such as “critical thinking,” “problem-solving,” and “higher level thought.”
For Dewey, the concept of reﬂective thought carried deep meaning. He saw reﬂection as a process that moves a learner from one experience into the next with deeper understanding of its relationships with and connections to other experiences and ideas. Thus, reﬂection leads the learner from the unclear to the clear.
Jean Piaget, who spent 50 years studying how children develop intellectually, became a major ﬁgure in the school of cognitive thought. His research led him to conclude there is always tension between assimilation (old ideas meeting new situations) and accommodation (changing the old ideas to meet the new situations). The resolution of this tension results in intellectual growth. Thus, humans develop cognitive skills through active interaction with the world (a basic premise of scenario-based training (SBT), discussed later in this chapter).
An American psychologist who studied with Piaget, Jerome Bruner became interested in how intellectual development related to the process of learning, His research led him to advocate learning from the known to the unknown, or from the concrete to the abstract, because humans best learn when relating new knowledge to existing knowledge. He introduced and developed the concept of the spiral curriculum, which revisits basic ideas repeatedly and builds on them in increasingly sophisticated ways as the student matures and develops.
Consider the opening scenario with Bill and Beverly. Bill might effectively use this theory with Beverly because she arrived at her ﬁrst class with a store of aviation facts. Building upon this knowledge, Bill can teach her how to keep the aircraft in straight and level ﬂight while he reinforces what she knows about basic aerodynamics via demonstration and discussion. Since aerodynamics is a constant thread in the ﬂight lessons, Bill is also able to employ the spiral curriculum concept in future lesson by repeatedly revisiting the basic concepts and building upon them as Beverly’s skill and knowledge increase.
In the mid-1900s, a group of educators led by Benjamin Bloom tried to classify the levels of thinking behaviors thought to be important in the processes of learning. [Figure 2-4] They wanted to classify education goals and objectives based on the assumption that abilities can be measured along a continuum from simple to complex. The result, which remains a popular framework for cognitive theory, was Bloom’s Taxonomy of the Cognitive Domain. The taxonomy (a classiﬁcation system according to presumed relationships) comprises six levels of intellectual behavior and progresses from the simplest to the most complex: knowledge, comprehension, application, analysis, synthesis, and evaluation. For more detailed information about the taxonomy, see Domains of Learning.
Figure 2-4. Bloom’s Taxonomy of the Cognitive Domain.
Continued research into cognitive theory has led to theories such as information processing and constructivism.
Information Processing Theory
Information processing theory uses a computer system as a model for human learning. The human brain processes incoming information, stores and retrieves it, and generates responses to the information. This involves a number of cognitive processes: gathering and representing information (encoding), retaining of information, and retrieving the information when needed.
This learning system has limitations and must be operated properly. A computer gets input from a keyboard, mouse, etc., whereas the human brain gets input from the senses of sight, hearing, touch, taste, and smell. The amount of sensory input the brain receives per second ranges from thousands to millions of bits of information according to various theories. Regardless of the number, that is a lot of information for the brain to track and process.
One way the brain deals with all this information is to let many of the habitual and routine things go unnoticed. For example, a pilot who uses the rudder when entering a turn is usually unaware of pressing the pedal, even though it involves moving a leg, exerting pressure on the pedal, etc. The human unconscious takes charge, leaving conscious thought processes free to deal with issues that are not habitual.
Since information processing theorists approach learning primarily through a study of memory, this learning concept is revisited during the discussion of memory.
A derivative of cognitive theory, constructivism is a philosophy of learning that can be traced to the eighteenth century. This theory holds that learners do not acquire knowledge and skills passively but actively build or construct them based on their experiences. As implied by its name, constructivism emphasizes the constructing or building that goes on in a learner’s mind when he or she learns. Therefore, it creates a learner-centered learning environment in which learners assume responsibility for their own learning.
According to constructivism, humans construct a unique mental image by combining preexisting information with the information received from sense organs. Learning is the result of the learner matching new information against this preexisting information and integrating it into meaningful connections. In constructivist thinking, learners are given more latitude to become effective problem solvers, identifying and evaluating problems, as well as deciphering ways in which to transfer their learning to these problems, all of which foster critical thinking skills. While the student is at the center of the learning process, an experienced teacher is necessary to guide them through the information jungle. Constructivism techniques are good for some types of learning, some situations, and some learners, but not all. This school of thought also encourages teaching students how to use what are known as the higher order thinking skills (HOTS) from Bloom’s Taxonomy and training based on problems or scenarios.
Higher Order Thinking Skills (HOTS)
The constructivist theory of learning explains and supports the learning of HOTS, which is commonly called aeronautical decision-making (ADM) in aviation. HOTS lie in the last three categories on Bloom’s Taxonomy of Learning: analysis, synthesis, and evaluation skills. Teaching the higher level thinking skills which are essential to judgment, decision-making, and critical thinking is important to aviation because a common thread in aviation accidents is the absence of higher order thinking skills (see Appendix F).
HOTS are taught like other cognitive skills, from simple to complex and from concrete to abstract. To teach HOTS effectively involves strategies and methods that include (1) using problem-based learning (PBL) instruction, (2) authentic problems, (3) real world problems, (4) student-centered learning, (5) active learning, (6) cooperative learning, and (7) customized instruction to meet the individual learner’s needs. These strategies engage the learner in some form of mental activity, have the learner examine that mental activity and select the best solution, and challenge the learner to explore other ways to accomplish the task or the problem.
It must be remembered that critical thinking skills should be taught in the context of subject matter. Learners progress from simple to complex; therefore, they need some information before they can think about a subject beyond rote learning. For example, knowing that compliance with the weight-and-balance limits of any aircraft is critical to ﬂight safety will not help an aviation student interpret weight-and-balance charts unless he or she knows something about how center of gravity interacts with weight and balance.
If the student does not yet have much subject matter knowledge, draw on the student’s experiences to gain entry into complex concepts. For example, most students probably played on a seesaw during their childhood. Thus, they have a basic experience of how weight and balance work around a center of gravity.
Additionally, HOTS must be emphasized throughout a program of study for best results. For aviation, this means HOTS should be taught in the initial pilot training program and in every subsequent pilot training program. Instructors need to teach the cognitive skills used in problem-solving until these techniques become automated and transferable to new situations or problems. Cognitive research has shown the learning of HOTS is not a change in observable behavior but the construction of meaning from experience.
Scenario-Based Training (SBT)
At the heart of HOTS lies scenario-based training (SBT) which is an example of the PBL instructional method and facilitates the enhancement of learning and the development and transference of thinking skills. SBT provides more realistic decision-making opportunities because it presents tasks in an operational environment; it correlates new information with previous knowledge, and introduces new information in a realistic context.
SBT is a training system that uses a structured script of “real world” scenarios to address ﬂight-training objectives in an operational environment. Such training can include initial training, transition training, upgrade training, recurrent training, and special training.
The instructor should adapt the scenarios to the aircraft, its specific flight characteristics and the likely flight environment, and should always require the student to make real-time decisions in a realistic setting. The scenarios should always be planned and led by the student (with the exception of the ﬁrst ﬂight or two or until the student has developed the required skills).
SBT not only meets the challenge of teaching aeronautical knowledge to the application level of learning, but also enables the instructor to teach the underlying HOTS needed to improve ADM. The best use of scenarios draws the learner into formulating possible solutions, evaluating the possible solutions, deciding on a solution, judging the appropriateness of that decision and ﬁnally, reﬂecting on the mental process used in solving the problem. It causes the learner to consider whether the decision led to the best possible outcome and challenges the learner to consider other solutions.
SBT scenarios help learners better understand the decisions they have to make and also helps focus the learner on the decisions and consequences involved. It is being used to train people in everything from emergency response to hotel management. The strength of SBT lies in helping the learner gain a deeper understanding of the information and in the learner improving his or her ability to recall the information. This goal is reached when the material is presented as an authentic problem in a situated environment that allows the learner to “make meaning” of the information based on his or her past experience and personal interpretation.
SBT has become one of the primary methods to teach today’s aviation learners how to make good aeronautical decisions which in turn enhances the safety of all aviation related activities. For information on how to incorporate SBT into a training syllabus, refer to chapter 9.
Initially, all learning comes from perceptions, which are directed to the brain by one or more of the ﬁve senses: sight, hearing, touch, smell, and taste. Psychologists have also found that learning occurs most rapidly when information is received through more than one sense. [Figure 2-5]
Figure 2-5. Most learning occurs through sight, but the combination of sight and hearing accounts for about 88 percent of all perception.
Perception involves more than the reception of stimuli from the ﬁve senses; it also involves a person giving meaning to sensations. People base their actions on the way they believe things to be. The experienced AMT, for example, perceives an engine malfunction quite differently than does an inexperienced student. This occurs because the beginning aviation student is overwhelmed by stimuli and often focuses on meaningless things, thus missing key information. It is important for the instructor to direct trainee’s perceptions initially so that the student detects and perceives relevant information.
Real meaning comes only from within a person, even though the perceptions, which evoke these meanings, result from external stimuli. The meanings, which are derived from perceptions, are inﬂuenced not only by the individual’s experience, but also by many other factors. Knowledge of the factors that affect the perceptual process is very important to the aviation instructor because perceptions are the basis of all learning.
Factors That Affect Perception
Both internal and external factors affect an individual’s ability to perceive:
Goals and values
Time and opportunity
Element of threat
The physical organism provides individuals with the perceptual apparatus for sensing the world around them. Pilots, for example, must be able to see, hear, feel, and respond adequately while they are in the air.
Goals and Values
Perceptions depend on one’s values and goals. Every experience and sensation, which is funneled into one’s central nervous system, is colored by the individual’s own beliefs and value structures. Spectators at a ball game may see an infraction or foul differently depending on which team they support. The values of the student are important for the instructor to know, because this knowledge assists in predicting how the student interprets experiences and instructions.
Goals are also a product of one’s value structure. Things that are more highly valued and cherished are pursued; those accorded less value and importance are not sought after.
Self-concept is a powerful determinant in learning. A student’s self-image, described in such terms as “conﬁdent” or “insecure,” has a great inﬂuence on the total perceptual process. If a student’s experiences tend to support a favorable self-image, the student tends to remain receptive to subsequent experiences. If a student has negative experiences, which tend to contradict self-concept, there is a tendency to reject additional training.
A negative self-concept inhibits the perceptual processes by introducing psychological barriers, which tend to keep the student from perceiving. They may also inhibit the ability to properly implement what is perceived. That is, self-concept affects the ability to actually perform or do things unfavorably. Students who view themselves positively, on the other hand, are less defensive and more receptive to new experiences, instructions, and demonstrations.
Time and Opportunity
It takes time and opportunity to perceive. Learning some things depends on other perceptions, which have preceded these learnings, and on the availability of time to sense and relate these new things to the earlier perceptions. Thus, proper sequence and time are necessary.
A student could probably stall an aircraft on the ﬁrst attempt, regardless of previous experience. Stalls cannot really be learned, however, unless some experience in normal ﬂight has been acquired. Even with such experience, time and practice are needed to relate the new sensations and experiences associated with stalls in order to develop a perception of the stall. In general, lengthening an experience and increasing its frequency are the most obvious ways to speed up learning, although this is not always effective. Many factors, in addition to the length and frequency of training periods, affect the rate of learning. The effectiveness of the use of a properly planned training syllabus is proportional to the consideration it gives to the time and opportunity factor in perception.
Element of Threat
The element of threat does not promote effective learning. In fact, fear adversely affects perception by narrowing the perceptual ﬁeld. Confronted with threat, students tend to limit their attention to the threatening object or condition. The ﬁeld of vision is reduced, for example, when an individual is frightened and all the perceptual faculties are focused on the thing that has generated fear.
Flight instruction provides many clear examples of this. During the initial practice of steep turns, Beverly may focus her attention on the altimeter and completely disregard outside visual references. Anything Bill does that is interpreted as threatening makes Beverly less able to accept the experience Bill is trying to provide. It adversely affects all her physical, emotional, and mental faculties.
Learning is a psychological process, not necessarily a logical one. Trying to frighten a student through threats of unsatisfactory reports or reprisals may seem logical, but is not effective psychologically. The effective instructor organizes teaching to ﬁt the psychological needs of the student. If a situation seems overwhelming, the student feels unable to handle all of the factors involved; a threat exists. As long as the student feels capable of coping with a situation, each new experience is viewed as a challenge.
A good instructor recognizes that behavior is directly inﬂuenced by the way a student perceives, and perception is affected by all of these factors. Therefore, it is important for the instructor to facilitate the learning process by avoiding any actions which may inhibit or prevent the attainment of teaching goals. Teaching is consistently effective only when those factors that inﬂuence perception are recognized and taken into account.
Insight involves the grouping of perceptions into meaningful wholes. Creating insight is one of the instructor’s major responsibilities. To ensure that this occurs, it is essential to keep each student constantly receptive to new experiences and to help the student understand how each piece relates to all other pieces of the total pattern of the task to be learned.
For example, during straight-and-level ﬂight in an aircraft with a ﬁxed-pitch propeller, the revolutions per minute (rpm) increase when the throttle is opened and decrease when it is closed. On the other hand, rpm changes can also result from changes in aircraft pitch attitude without changes in power setting. Obviously, engine speed, power setting, airspeed, and aircraft attitude are all related.
True learning requires an understanding of how each factor may affect all of the others and, at the same time, knowledge of how a change in any one of them may affect all of the others. This mental relating and grouping of associated perceptions is called insight.
Insight almost always occurs eventually, whether or not instruction is provided. For this reason, it is possible for a person to become an electrician by trial and error, just as one may become a lawyer by reading law. Instruction, however, speeds this learning process by teaching the relationship of perceptions as they occur, thus promoting the development of the student’s insight.
As perceptions increase in number, the student develops insight by assembling them into larger blocks of learning. As a result, learning becomes more meaningful and more permanent. Forgetting is less of a problem when there are more anchor points for tying insights together. It is a major responsibility of the instructor to organize demonstrations and explanations, and to direct practice so that the student has better opportunities to understand the interrelationship of the many kinds of experiences that have been perceived. Pointing out the relationships as they occur, providing a secure and nonthreatening environment in which to learn, and helping the student acquire and maintain a favorable self-concept are key steps in fostering the development of insight.
Part of an aviation instructor’s job is helping students acquire knowledge. In this context, knowledge refers to information that humans are consciously aware of and can articulate. For example, knowledge of the fuel capacity of a particular aircraft, understanding how an internal combustion engine works, and the ability to determine the weight and balance of an aircraft are examples of knowledge.
Figure 2-6. A student acquires knowledge through memorization, understanding, and application.
Figure 2-6 shows the three phases of knowledge, a progression of how students acquire knowledge. Some practical considerations about learning new knowledge and instructor actions that help students acquire knowledge are summarized.
A student’s ﬁrst attempt to acquire knowledge about a new topic amounts to memorizing facts about steps in a procedure. For example, when Beverly is learning to use an altimeter, she may have memorized that the knob on the instrument is used to dial the current barometric pressure and that this number must be obtained from the recorded broadcast and set prior to ﬂight.
Memorizing facts and steps has an advantage: it allows students to get started quickly. For example, as soon as Beverly memorizes the purpose of the knob on the altimeter and the procedure for obtaining the current barometric pressure, she is able to properly conﬁgure the instrument for ﬂight.
The limitations of memorization become apparent when a student is asked to solve a problem or provide an explanation of something that is not covered by the newly acquired knowledge. For example, when asked whether she would rather have the altimeter mistakenly set too high or too low when ﬂying in mountainous terrain, Beverly may not have an answer.
A more experienced pilot can answer the altimeter question because she or he understands the ramifications of the question. Understanding, or the ability to notice similarities and make associations between the facts and procedural steps learned, is an important next stage in the knowledge acquisition process. At this stage, the learner begins to organize knowledge in useful ways and a collection of memorized facts gives way to understanding.
Understanding develops when students begin to organize known facts and steps into coherent groups that come together to form an understanding of how a thing or a process works. For example, after learning to adjust the mixture control in cruise ﬂight, Beverly learns that combustion requires a certain mixture of fuel and air, and that air becomes less dense as altitude increases.
Combining these two ideas, she now understands the purpose of the mixture control is to keep these two quantities in balance as the aircraft changes altitude. “Mental model” or self-explanation is often used to refer to an organized collection of ideas that forms a learner’s understanding of a thing or process.
The advantages of possessing this type of understanding include the following:
The learner is no longer limited to answering questions that match the memorized facts. For example, armed with the understanding of the mixture control, Beverly may now be able to produce answers to more challenging questions, such as what would happen if the mixture were set too rich or too lean.
Learners who understand a process have an easier time mastering variations of the processes, such as unfamiliar aircraft, new avionics systems, and unfamiliar airport procedures.
Understanding shared between people allows them to communicate more efﬁciently. For example, an experienced pilot might mention to an experienced mechanic that a magneto ran a bit rough during an engine run-up. This brief communication triggers access to a wealth of knowledge in the mind of the mechanic who instantly knows what must be done.
Learners who understand the purpose behind procedure steps are better able to remember the procedure steps later, or reconstruct them when they are forgotten.
Mental models evolve as learners take in new information. For example, Bill could ask Beverly why ﬂying with an inappropriate mixture setting is bad. A learner whose understanding includes knowledge about spark plugs and carbon deposits might answer correctly. If this same learner’s understanding later extends to include knowledge about thermal efﬁciency and the stoichiometric equation for the combustion of gasoline, the explanations are likely to become much more sophisticated. No individual’s understanding of anything is ever “complete.”
Concept learning is based on the assumption that humans tend to group objects, events, ideas, people, etc., that share one or more major attributes that set them apart. It also involves discrimination between types of things or ideas inside or outside of a concept set. By grouping information into concepts, humans reduce the complexities of life and create manageable categories. Although many theories about concept learning exist, categorization has always been a central aspect.
Concept learning enhances student understanding when students formulate generalized concepts from particular facts or steps. Generalized concepts are more powerful than facts because instead of literally describing one thing, they describe many things at once.
For example, a new ﬂight student who sees several examples of weight-shift control (WSC) aircraft may formulate a category for WSC aircraft based on the wing, which is large and fabric covered. The power of the category becomes obvious when the student sees a sport plane. Because of the similar wing, he or she immediately categorizes it as an ultra light and ascribes many of the properties of ultra light aircraft to the sport plane. In this way, the student has used a generalized concept to begin understanding something new.
Most learners exhibit a natural tendency to categorize and become adept at recognizing members of most any category they create. If something is encountered that does not ﬁt into a category, these learners formulate a new category or revise the deﬁnitions of existing categories. In the above example, the student eventually must revise the category of ultra light to light-sport aircraft which encompasses both types of aircraft. Therefore, an important part of the learning process is continual revision of the categories used when learners encounter new things or exceptions to things previously catalogued.
Another type of generalization is a schema (the cognitive framework that helps people organize and interpret information). Schemas can be revised by any new information and are useful because they allow people to take shortcuts in interpreting a vast amount of information.
Humans form schemas when they notice reoccurring patterns in things frequently observed or done. Schemas help learners interpret things they observe by priming them to expect certain elements that match the schema. For example, schemas demonstrate why an experienced pilot is able to listen to and read back a lengthy departure clearance issued by air trafﬁc control (ATC). Beginning ﬂight students often remember the controller’s use of the words “the” and “and” and fail to note more important words that describe assigned altitudes or radio frequencies. The experienced pilot is successful because he or she possesses a schema for this type of event and knows in advance that the clearance contains ﬁve key pieces of information. While listening to the clearance, the pilot anticipates and is primed to capture those ﬁve things.
Similarly, students create schemas for preﬂight inspection procedures and procedures required to operate advanced ﬂight deck systems such as autopilots or multifunction displays. As with categories, humans continuously learn new schemas and revise old ones to accommodate new things as they continue to learn. While schemas help humans deal with information, they can also make it difﬁcult to retain new information that does not conform to established schemas.
Thorndike and the Laws of Learning
One of the pioneers of educational psychology, E.L. Thorndike formulated three laws of learning in the early 20th century. [Figure 2-7] These laws are universally accepted and apply to all kinds of learning: the law of readiness, the law of exercise, and the law of effect. Since Thorndike set down his laws, three more have been added: the law of primacy, the law of intensity, and the law of recency.
Figure 2-7. E. L. Thorndike (1874–1949).
The basic needs of the learner must be satisﬁed before he or she is ready or capable of learning (see Chapter 1, Human Behavior). The instructor can do little to motivate the learner if these needs have not been met. This means the learner must want to learn the task being presented and must possess the requisite knowledge and skill. In SBT, the instructor attempts to make the task as meaningful as possible and to keep it within the learner’s capabilities.
Students best acquire new knowledge when they see a clear reason for doing so, often show a strong interest in learning what they believe they need to know next, and tend to set aside things for which they see no immediate need. For example, beginning ﬂight students commonly ignore the ﬂight instructor’s suggestion to use the trim control. These students believe the control yoke is an adequate way to manipulate the aircraft’s control surfaces. Later in training, when they must divert their attention away from the controls to other tasks, they realize the importance of trim.
Instructors can take two steps to keep their students in a state of readiness to learn. First, instructors should communicate a clear set of learning objectives to the student and relate each new topic to those objectives. Second, instructors should introduce topics in a logical order and leave students with a need to learn the next topic. The development and use of a well-designed curriculum accomplish this goal.
Readiness to learn also involves what is called the “teachable moment” or a moment of educational opportunity when a person is particularly responsive to being taught something. One of the most important skills to develop as an instructor is the ability to recognize and capitalize on “teachable moments” in aviation training. An instructor can ﬁnd or create teachable moments in ﬂight training activity: pattern work, air work in the local practice area, cross-country, ﬂight review, or instrument proﬁciency check.
Teachable moments present opportunities to convey information in a way that is relevant, effective, and memorable to the student. They occur when a learner can clearly see how speciﬁc information or skills can be used in the real world.
For example, while on ﬁnal approach several deer cross the runway. Bill capitalizes on this teachable moment to stress the importance of always being ready to perform a go-around.
All learning involves the formation of connections and connections are strengthened or weakened according to the law of effect. Responses to a situation that are followed by satisfaction are strengthened; responses followed by discomfort are weakened, either strengthening or weakening the connection of learning. Thus, learning is strengthened when accompanied by a pleasant or satisfying feeling, and weakened when associated with an unpleasant feeling. Experiences that produce feelings of defeat, frustration, anger, confusion, or futility are unpleasant for the student. For example, if Bill teaches landings to Beverly during the ﬁrst ﬂight, she is likely to feel inferior and be frustrated, which weakens the learning connection.
The learner needs to have success in order to have more success in the future. It is important for the instructor to create situations designed to promote success. Positive training experiences are more apt to lead to success and motivate the learner, while negative training experiences might stimulate forgetfulness or avoidance. When presented correctly, SBT provides immediate positive experiences in terms of real world applications.
To keep learning pleasant and to maintain student motivation, an instructor should make positive comments about the student’s progress before discussing areas that need improving. Flight instructors have an opportunity to do this during the ﬂight debrieﬁng. For example, Bill praises Beverly on her aircraft control during all phases of ﬂight, but offers constructive comments on how to better maintain the runway centerline during landings.
Connections are strengthened with practice and weakened when practice is discontinued, which reﬂects the adage “use it or lose it.” The learner needs to practice what has been learned in order to understand and remember the learning. Practice strengthens the learning connection; disuse weakens it. Exercise is most meaningful and effective when a skill is learned within the context of a real world application.
Primacy, the state of being ﬁrst, often creates a strong, almost unshakable impression and underlies the reason an instructor must teach correctly the ﬁrst time and the student must learn correctly the ﬁrst time. For example, a maintenance student learns a faulty riveting technique. Now the instructor must correct the bad habit and reteach the correct technique. Relearning is more difﬁcult than initial learning.
Also, if the task is learned in isolation, it is not initially applied to the overall performance, or if it must be relearned, the process can be confusing and time consuming. The ﬁrst experience should be positive, functional, and lay the foundation for all that is to follow.
Immediate, exciting, or dramatic learning connected to a real situation teaches a learner more than a routine or boring experience. Real world applications (scenarios) that integrate procedures and tasks the learner is capable of learning make a vivid impression and he or she is least likely to forget the experience. For example, using realistic scenarios has been shown to be effective in the development of proﬁciency in ﬂight maneuvers, tasks, and single-pilot resource management (SRM) skills.
The principle of recency states that things most recently learned are best remembered. Conversely, the further a learner is removed in time from a new fact or understanding, the more difﬁcult it is to remember. For example, it is easy for a learner to recall a torque value used a few minutes earlier, but it is more difﬁcult or even impossible to remember an unfamiliar one used a week earlier.
Instructors recognize the principle of recency when they carefully plan a summary for a ground school lesson, a shop period, or a postﬂight critique. The instructor repeats, restates, or reemphasizes important points at the end of a lesson to help the learner remember them. The principle of recency often determines the sequence of lectures within a course of instruction.
In SBT, the closer the training or learning time is to the time of the actual scenario, the more apt the learner is to perform successfully. This law is most effectively addressed by making the training experience as much like the scenario as possible.
Domains of Learning
As mentioned during the discussion of Cognitive Theory, Dr. Bloom played a central role in transforming the ﬁeld of educational psychology. Interested in what and how people learn, he proposed a framework to help understand the major areas of learning and thinking. He ﬁrst classiﬁed them into three large groups [Figure 2-8] called the domains of learning:
Figure 2-8. An overview of the three learning domains.
The group effort to classify the levels of thinking behaviors thought to be important in the processes of learning mentioned earlier in the chapter led to Bloom’s Taxonomy of the Cognitive Domain. One of the best known educational domains, it includes remembering speciﬁc facts (content knowledge) and concepts that help develop intellectual abilities and skills. There are six major categories, starting from the simplest behavior (recalling facts) to the most complex (evaluation). [Figure 2-9]
Figure 2-9. The six major levels of Bloom’s Taxonomy of the Cognitive Domain with types of behavior and examples of objectives.
The four practical learning levels are rote, understanding, application, and correlation. [Figure 2-10] The lowest level is the ability to repeat something which one has been taught, without understanding or being able to apply what has been learned. This is referred to as rote learning. The fact level is a single concept. The key verbs which describe or measure this activity are words such as deﬁne, identify, and label. The comprehension or understanding level puts two or more concepts together and uses verbs such as describe, estimate, or explain. The application level puts two or more concepts together to form something new. Typical verbs at this level include “determine,” “develop,” and “solve.”
Figure 2-10. Learning is progressive and occurs at several basic levels.
For example, Bill may explain the procedure for entering a level, left turn to Beverly. The procedure includes several steps: (1) visually clear the area, (2) add a slight amount of power to maintain airspeed, (3) apply aileron control pressure to the left, (4) add sufﬁcient rudder pressure in the direction of the turn to avoid slipping and skidding, and (5) increase back pressure to maintain altitude. When Beverly verbally repeats this instruction, she has learned the procedure by rote. This will not be very useful to her if there is never an opportunity to make a turn in ﬂight, or if she has no knowledge of the function of aircraft controls.
With proper instruction on the effect and use of the ﬂight controls, and experience in controlling the aircraft during straight-and-level ﬂight, Beverly can consolidate old and new perceptions into an insight on how to make a turn. At this point, she has developed an understanding of the procedure for turning the aircraft in ﬂight. This understanding is basic to effective learning, but may not necessarily enable her to make a correct turn on the ﬁrst attempt.
When Beverly understands the procedure for entering a turn, has had turns demonstrated, and has practiced turn entries until consistency has been achieved, she has developed the skill to apply what has been learned. This is a major level of learning, and one at which the instructor is too often willing to stop. Discontinuing instruction on turn entries at this point and directing subsequent instruction exclusively to other elements of piloting performance is characteristic of piecemeal instruction, which is usually inefﬁcient.
The correlation level of learning, which should be the objective of aviation instruction, is that level at which the student becomes able to associate an element which has been learned with other segments or blocks of learning. The other segments may be items or skills previously learned, or new learning tasks to be undertaken in the future. When Beverly has achieved this level of learning in turn entries, for example, she has developed the ability to correlate the elements of turn entries with the performance in trafﬁc patterns.
The three higher thinking skills instructional levels include analysis, synthesis and evaluation (or HOTS level previously mentioned in the learning theory section). The analysis level involves breaking the information into its component parts, examining, and trying to understand the information in order to develop conclusions, make inferences, and/or ﬁnd evidence to support generalizations. This level uses such verbs as points out, differentiate distinguish, examine, discriminate, compare, outline, prioritize, recognize, or subdivide.
Synthesis involves putting parts together to form a new and integrated whole. Typical verbs for this level include create, design, plan, organize, generate, write, adapt, compare, formulate, devise, model, revise, or incorporate. The ﬁnal level in the taxonomy is evaluation and involves making judgments about the merits of ideas, materials, or phenomena. The following example demonstrates the difference between learning on the ﬁrst three levels versus learning critical thinking skills.
Bill provides a detailed explanation on how to control for wind drift. The explanation includes a thorough coverage of heading, speed, angle of bank, altitude, terrain, and wind direction plus velocity. The explanation is followed by a demonstration and repeated practice of a speciﬁc ﬂight maneuver, such as turns around a point or S-turns across the road until the maneuver can be consistently accomplished in a safe and effective manner within a speciﬁed limit of heading, altitude, and airspeed. At the end of this lesson, Beverly is only capable of performing the maneuver.
Then Bill asks Beverly to plan for the arrival at a speciﬁc nontowered airport. The planning should take into consideration the possible wind conditions, arrival paths, airport information and communication procedures, available runways, recommended trafﬁc patterns, courses of action, and preparation for unexpected situations. Upon arrival at the airport, Beverly makes decisions (with guidance and feedback as necessary) to safely enter and ﬂy the trafﬁc pattern. This is followed by a discussion of what was done, why it was done, the consequences, and other possible courses of action and how it applies to other airports. At the end of this lesson the student is capable of explaining the safe arrival at any nontowered airport in any wind condition.
For aviation instructors, educational objectives for the ﬁrst three levels (knowledge, comprehension, and application) are generally gained as the result of attending a ground school, reading about aircraft systems, listening to a preﬂight brieﬁng, or taking part in computer-based training. The highest educational objective levels in this domain (analysis, synthesis, and evaluation) can be acquired through SBT training. For example, the student pilot learns to correctly evaluate a ﬂight maneuver or the maintenance student repairs an aircraft engine. Sample questions for each level of the cognitive domain are provided in the graph. Thus, SBT correctly utilized reinforces the three higher level thinking skills.
The affective domain addresses a learner’s emotions toward the learning experience. It includes feelings, values, enthusiasms, motivations, and attitudes. [Figure 2-11] For the aviation instructor, this may mean how the student approaches learning. Is he or she motivated to learn? Does he or she exhibit conﬁdence in learning? Does the student have a positive attitude toward safety?
Figure 2-11. The affective domain (attitudes, beliefs, and values) contains five educational objective levels.
The affective domain provides a framework for teaching in ﬁve levels: awareness, response, value, organizing, and integration. In this taxonomy, the learner begins on the awareness level and is open to learning, willing to listen to the instructor. As the learner traverses the taxonomy, he or she responds by participating actively in the training, decides the value of the training, organizes the training into his or her personal belief system, and ﬁnally internalizes it.
The affective domain is more difficult to measure, but motivation and enthusiasm are important components of any learning. Therefore, the aviation instructor should be acquainted with this facet of learning. Motivation is discussed in depth later in the chapter.
The psychomotor domain is skill based and includes physical movement, coordination, and use of the motor-skill areas. [Figure 2-12] Development of these skills requires repetitive practice and is measured in terms of speed, precision, distance, and techniques. While various examples of the psychomotor domain exist, the practical instructional levels for aviation training purposes include observation, imitation, practice, and habit. This domain is an important component of instruction when aviation instructors prepare students for the practical test.
Figure 2-12. The psychomotor domain (physical skills) consists of seven educational objective levels.
At the ﬁrst level, the learner observes a more experienced person perform the skill. The instructor has the learner observe sequences and relationships that lead to the ﬁnished product. Observation may be supplemented by reading, watching a DVD, or computer-based training. The second level is imitation in which the learner attempts to copy the skill under the watchful eye of the instructor.
The practice level is a proﬁciency building experience in which the learner tries a speciﬁc activity over and over. It may be conducted by the learner without direct oversight of the instructor, such as touch-and-go landings for the ﬂight student who has ﬂown a successful solo ﬂight. The habit level is reached when the student can perform the skill in twice the time that it takes the instructor or an expert to perform. The evaluation of ability is a performance or skill test. If a person continues to perfect a skill, it eventually becomes a skill performed at the expert level.
Skills involving the psychomotor domain include learning to ﬂy a precision instrument approach procedure, programming a global positioning system (GPS) receiver, or using sophisticated maintenance equipment. As physical tasks and equipment become more complex, the requirement for integration of cognitive and physical skills increases.
Summary of Instructor Actions
To help students acquire knowledge, the instructor should:
Ask students to recite or practice newly acquired knowledge.
Ask questions that probe student understanding and prompt them to think about what they have learned in different ways.
Present opportunities for students to apply what they know to solving problems or making decisions.
Present students with problems and decisions that test the limits of their knowledge.
Demonstrate the beneﬁts of understanding and being able to apply knowledge.
Introduce new topics as they support the objectives of the lesson, whenever possible.
These additional levels of learning are the basis of the knowledge, attitude, and skill learning objectives commonly used in advanced qualiﬁcation programs for airline training. They also can be tied to the PTS to show the level of knowledge or skill required for a particular task. A list of action verbs for the three domains shows appropriate behavioral objectives at each level. [Figure 2-13] Instructors who are familiar with curriculum development recognize that the action verbs are examples of performance-based objectives.
Figure 2-13. A listing such as the one shown here is useful for development of almost any training program.
Characteristics of Learning
The ability to learn is one of the most outstanding human characteristics. Learning occurs continuously throughout a person’s lifetime. To understand how people learn, it is necessary to understand what happens to the individual during the process. In spite of numerous theories and contrasting views, psychologists generally agree there are many characteristics of learning.
Knowledge of the general characteristics of learning help an aviation instructor use them in a learning situation. If learning is a change in behavior as a result of experience, then instruction must include a careful and systematic creation of those experiences that promote learning. This process can be quite complex because, among other things, an individual’s background strongly inﬂuences the way that person learns. To be effective, the learning situation also should be purposeful, based on experience, multifaceted, and involve an active process.
Learning Is Purposeful
Each student sees a learning situation from a different viewpoint. Each student is a unique individual whose past experiences affect readiness to learn and understanding of the requirements involved. For example, an instructor may give two aviation maintenance students the assignment of learning certain inspection procedures. One student may learn quickly and be able to competently present the assigned material. The combination of an aviation background and future goals may enable that student to realize the need and value of learning the procedures. A second student’s goal may only be to comply with the instructor’s assignment, and may result in only minimum preparation. The responses differ because each student acts in accordance with what he or she sees in the situation.
Most people have fairly deﬁnite ideas about what they want to do and achieve. Their goals sometimes are short term, involving a matter of days or weeks. On the other hand, their goals may be carefully planned for a career or a lifetime. Each student has speciﬁc intentions and goals. Some may be shared by other students. Students learn from any activity that tends to further their goals. Their individual needs and attitudes may determine what they learn as much as what the instructor is trying to get them to learn. In the process of learning, the student’s goals are of paramount signiﬁcance. To be effective, aviation instructors need to ﬁnd ways to relate new learning to the student’s goals.
Learning Is a Result of Experience
Since learning is an individual process, the instructor cannot do it for the student. The student can learn only from personal experiences; therefore, learning and knowledge cannot exist apart from a person. A person’s knowledge is a result of experience, and no two people have had identical experiences. Even when observing the same event, two people react differently; they learn different things from it, according to the manner in which the situation affects their individual needs. Previous experience conditions a person to respond to some things and to ignore others.
All learning is by experience, but learning takes place in different forms and in varying degrees of richness and depth. For instance, some experiences involve the whole person while others may be based only on hearing and memory. Aviation instructors are faced with the problem of providing learning experiences that are meaningful, varied, and appropriate. As an example, students can learn to say a list of words through repeated drill, or they can learn to recite certain principles of ﬂight by rote. However, they can make them meaningful only if they understand them well enough to apply them correctly to real situations. If an experience challenges the students, requires involvement with feelings, thoughts, memory of past experiences, and physical activity, it is more effective than a learning experience in which all the students have to do is commit something to memory.
It seems clear enough that the learning of a physical skill requires actual experience in performing that skill. Student pilots learn to ﬂy aircraft only if their experiences include ﬂying them; student AMTs learn to overhaul power plants only by actually performing that task. Mental habits are also learned through practice. If students are to use sound judgment and develop decision-making skills, they need learning experiences that involve knowledge of general principles and require the use of judgment in solving realistic problems.
Learning Is Multifaceted
If instructors see their objective as being only to train their students’ memory and muscles, they are underestimating the potential of the teaching situation. Students learn much more than expected if they fully exercise their minds and feelings. The fact that these items were not included in the instructor’s plan does not prevent them from inﬂuencing the learning situation.
Psychologists sometimes classify learning by types, such as verbal, conceptual, perceptual, motor, problem-solving, and emotional. Other classiﬁcations refer to intellectual skills, cognitive strategies, and attitudinal changes, along with descriptive terms like surface or deep learning. However useful these divisions may be, they are somewhat artiﬁcial. For example, a class learning to apply the scientiﬁc method of problem-solving may learn the method by trying to solve real problems. But in doing so, the class also engages in verbal learning and sensory perception at the same time. Each student approaches the task with preconceived ideas and feelings, and for many students, these ideas change as a result of experience. Therefore, the learning process may include verbal elements, conceptual elements, perceptual elements, emotional elements, and problem-solving elements all taking place at once. This aspect of learning will become more evident later in this handbook when lesson planning is discussed.
Learning is multifaceted in still another way. While learning the subject at hand, students may be learning other things as well. They may be developing attitudes about aviation—good or bad—depending on what they experience. Under a skillful instructor, they may learn self-reliance. The list is seemingly endless. This type of learning is sometimes referred to as incidental, but it may have a great impact on the total development of the student.
Learning Is an Active Process
Students do not soak up knowledge like a sponge absorbs water. The instructor cannot assume that students remember something just because they were in the classroom, shop, or aircraft when the instructor presented the material. Neither can the instructor assume the students can apply what they know because they can quote the correct answer verbatim. For students to learn, they need to react and respond, perhaps outwardly, perhaps only inwardly, emotionally, or intellectually.
Learning styles are simply different approaches or ways of learning based on the fact that people absorb and process information in different ways. Learning style is an individual’s preference for understanding experiences and changing them into knowledge. It denotes the typical strategy a learner adopts in a learning situation. For example, information may be learned in a variety of ways: by seeing or hearing, by reﬂecting or acting, analyzing or visualizing, or it may be learned piecemeal or steadily. Just as people learn differently, they also have different teaching methods. Some instructors rely on lectures, others demonstrate, and others may prefer computer simulation training. Everyone has a mixture of strengths and preferences, not a single style or preference to the complete exclusion of any other. Please bear this in mind when using these ideas.
As mentioned in chapter 1 and the discussion of personality types and learning, underpinning the idea of learning style is the theory that everyone has an individual style of learning. According to this approach to learning, if the student and instructor work with that style, rather than against it, both beneﬁt. Currently, 71 different theories of learning styles have been identiﬁed. These theories run from simple to complex, usually reﬂecting scientiﬁc research about how the brain processes information. While the scientiﬁc community may be surprised at how the research has been used, many educators and school systems have become advocates of applying learning style to teaching methods.
Another model for learning, the Approaches to Learning model, bases its theory on the student’s learning intentions. For example, is the student interested in short-term memorization of the material or long-term knowledge? Does the student want a passing grade on a pop quiz or the ability to use the material learned to repair an engine? One feature of the Approaches to Learning is that the learner’s approach to learning depends on his or her reasons for learning. This theory reﬂects the chapter 1 discussion of adult learners who come to aviation training with deﬁnite reasons for learning.
While controversy exists over the scientiﬁc value of learning styles as well as approaches to learning, many educational psychologists advocate their use in the learning process. Knowledge of learning styles and approaches can help an instructor make adjustments in how material is presented if his or her learning/teaching style differs from the way a student learns. Since a student’s information processing technique, personality, social interaction tendencies, and the instructional methods used are all signiﬁcant factors, training programs should be sensitive to different learning styles.
Right Brain/Left Brain
According to research on the human brain, people have a preferred side of the brain to use for understanding and storing information. While both sides of the brain are involved in nearly every human activity, it has been shown that those with right-brain dominance are characterized as being spatially oriented, creative, intuitive, and emotional. Those with left-brain dominance are more verbal, analytical, and objective. Generally, the brain functions as a whole. For example, the right hemisphere may recognize a face, while the left associates a name to go with the face.
While most people seem to have a dominant side, it is a preference, not an absolute. On the other hand, when learning is new, difﬁcult, or stressful, the brain seems to go on autopilot to the preferred side. Recognizing a student’s dominant brain hemisphere gives the instructor a guide for ways to teach and reinforce learning. There are also some people who use both sides of the brain equally well for understanding and storing information. [Figure 2-14]
Figure 2-14. The importance of recognizing a dominant brain hemisphere gives the instructor a guide for ways to teach and reinforce learning.
As seen in Figure 2-14, right and left brain learners have preferences for how they process information. Based on information processing theory, left brain learners or serialist learners have an analytic approach to learning. Because they gain understanding in linear steps, with each step logically following the previous one, these learners need well-deﬁned, sequential steps where the overall picture is developed slowly, thoroughly, and logically. This is a bottom-up strategy.
Right brain or holistic learners favor the holist strategy and prefer a big picture or global perspective. This is a top-down strategy and learners tend to learn in large jumps, absorbing material almost randomly without seeing connections, until suddenly “it” clicks and they get it. Global learners solve complex problems rapidly once they have grasped the big picture, but they often have difﬁculty explaining how they did it. This type of learner seeks overall comprehension; analogies help this learner.
Index of Learning Styles (ILS)
In 1988, Richard Felder and Linda Silverman designed a learning style model with parallel learning styles that classiﬁed students as having learning preferences in sensing or intuitive, visual or verbal, active or reﬂective, sequential or global (discussed under holistic/serialist learning style. Dr. Felder maintains a website at www4.ncsu.edu/unity/lockers/users/f/felder/public/RMF.html that offers learners the opportunity to assess learning preferences at no cost for noncommercial purposes. [Figure 2-15]
Figure 2-15. Some of the different traits utilized by each learning style.
Visual, Auditory, Kinesthetic Learners (VAK)
One of the most popular learning styles is based on the three main sensory receptors: vision, hearing, and touch. These are called visual, auditory, and kinesthetic learning styles (VAK). [Figure 2-16] Research in this area dates back to the early 20th century and the concepts were developed over many years by psychologists and teaching specialists. Others have augmented the VAK model with the addition of R for “reading” (VARK), or the addition of T for “tactile” (VAKT), or even a combination of the terms for VARKT.
Figure 2-16. Visual, auditory, and kinesthetic learning styles (VAK).
Learners generally use all three styles to receive information, but one of these three ways of receiving information is dominant. Once again, the dominant style of receiving information is the best way for a person to learn new information, but this style may not be the same for every task. The learner may use one style of learning or a combination of styles depending on the learning task.
Visual learners rely on seeing to learn. They learn best if a major component of the lesson is something they can see, and work best with printed and graphic materials, and visual displays including diagrams, illustrated text books, overhead transparencies, videos, ﬂip charts, and hand-outs. They store information in their brains as pictures or images. They like to take extensive notes. Statistically, most people are visual learners.
Auditory learners transfer knowledge through listening and speaking. These learners need an oral component to the lesson such as verbal instructions. These learners have excellent listening skills and remember what was discussed over what was seen. They are better at verbally explaining than at writing. Since auditory learners prefer to listen to material, they are not good note takers.
Kinesthetic learners process and store information through physical experience such as touching, manipulating, using, or doing. They like to move around while trying to solve a problem and learn best when the material being taught involves hands-on practical experiences. Their concentration tends to wander when there is no external stimulation. They also learn from demonstration by watching carefully, then imagining or mirroring the demonstrator’s movements.
Learners may prefer one of these three learning styles over another, but most learners employ all three depending on the material being learned. For example, when Beverly makes her ﬁrst landing with Bill guiding her attempt, she employs visual, auditory, and kinesthetic learning. As the aircraft enters downwind, Beverly uses visual cues to recognize the airport and landing strip as she lines the aircraft up to land. As Bill talks her through the procedures, Beverly is using her auditory learning skills to learn how to land the aircraft. Finally, she needs to use kinesthetic skills to perform the actual landing.
Remember, good learners are capable of processing information in a variety of ways. The key to meeting individual student needs is to ensure a variety of learning styles are addressed in every lesson.
In a theory proposed by Ricki Linksman, the learning style ideas discussed in the preceding paragraphs have been melded into a concept based on the VAKT learning styles plus brain hemisphere preference. This “superlink,” as she calls it, is the easiest way for a learner to process information in order to understand, remember, and retain it. Matching visual, auditory, kinesthetic, and tactile with right- and left-brain research, Linksman created eight superlinks: visual left-brain, visual right-brain, auditory left-brain, auditory right-brain, tactile left-brain, tactile right-brain, kinesthetic left-brain, and kinesthetic right-brain. These superlinks accelerate learning by targeting the best way a person learns.
As mentioned earlier, there are many models of how people learn. Some models identify styles or approaches that are easily recognized such as collaborative, sharing students who enjoy working with others, versus competitive students who are grade conscious and feel they must do better than their peers. Participant students normally have a desire to learn and enjoy attending class, and avoidant students do not take part in class activities and have little interest in learning.
The learning environment also inﬂuences learning style. In real life, most students ﬁnd it necessary to adapt to a traditional style-learning environment provided by a school, university, or other educational/training establishment. Sometimes, the student’s way of learning may or may not be compatible with his or her environment.
Instructors who recognize either the learning style or learning approach of students and problems associated with them are more effective teachers than those who do not. Also, these instructors are prepared to develop appropriate lesson plans and provide guidance, counseling, or other advisory services, as required.
Acquiring Skill Knowledge
An aviation instructor also helps a student acquire skill knowledge, which is knowledge reﬂected in motor or manual skills and in cognitive or mental skills, that manifests itself in the doing of something. Thus, skill knowledge differs from declarative knowledge because the student is not usually aware of it consciously or able to articulate the skill. Evidence of skill knowledge is gained through observations of performance. This knowledge of how to do things is based on extensive practice, which leads to the storage of skill knowledge. An everyday example of skill knowledge is the ability to ride a bicycle.
Skill knowledge is acquired slowly through related experience. For example, a maintenance student who is learning to weld typically burns or cracks the metal being welded while an expert welder’s work is free of such imperfections. What does the experienced welder “know” that the beginner does not? The expert welder has had many hours of practice and a knowing-is-in-the-doing ability the inexperienced welder lacks. It isn’t always possible to reduce to mere words that which one knows or knows how to do.
Stages of Skill Acquisition
Students make their way from beginner to expert via three stages of skill knowledge acquisition, helping students transition from beginner to expert. The development of any skill acquisition (or the learning process) has three characteristic stages: cognitive, associative, and automaticity. An instructor must learn to recognize each stage in student performance in order to assess student progress.
Cognitive learning has a basis in factual knowledge. Since the student has no prior knowledge of ﬂying, the instructor first introduces him or her to a basic skill. The student then memorizes the steps required to perform the skill. As the student carries out these memorized steps, he or she is often unaware of progress, or may ﬁxate on one aspect of performance. Performing the skill at this stage typically requires all the student’s attention; distractions introduced by an instructor often cause performance to deteriorate or stop.
The best way to prepare the student to perform a task is to provide a clear, step-by-step example. Having a model to follow permits students to get a clear picture of each step in the sequence so they understand what is required and how to do it. In ﬂight or maintenance training, the instructor provides the demonstration, emphasizing the steps and techniques. During classroom instruction, an outside expert may be used, either in person or in a video presentation. In any case, students need to have a clear impression of what they are to do.
For example, Beverly enters a steep turn after increasing power by a prescribed amount and adjusting the pitch trim. She ﬁxates on the attitude indicator as she attempts to achieve the desired bank angle. The bank angle exceeds tolerances as she struggles to correct it, making many abrupt control inputs.
Even demonstrating how to do something does not result in the student learning the skill. Practice is necessary in order for the student to learn how to coordinate muscles with visual and tactile senses. Learning to perform various aircraft maintenance skills or ﬂight maneuvers requires practice. Another beneﬁt of practice is that as the student gains proﬁciency in a skill, verbal instructions become more meaningful. A long, detailed explanation is confusing before the student begins performing, whereas speciﬁc comments are more meaningful and useful after the skill has been partially mastered.
As the storage of a skill via practice continues, the student learns to associate individual steps in performance with likely outcomes. The student no longer performs a series of memorized steps, but is able to assess his or her progress along the way and make adjustments in performance. Performing the skill still requires deliberate attention, but the student is better able to deal with distractions.
For example, Beverly enters the steep turn and again struggles to achieve the desired bank angle. Still working on the bank angle, she remembers the persistent altitude control problem and glances at the altimeter. Noticing that the aircraft has descended almost 100 feet, she increases back pressure on the control and adjusts the trim slightly. She goes back to a continuing struggle with the bank angle, keeping it under control with some effort, and completes the turn 80 feet higher than started.
Automatic Response Stage
Automaticity is one of the by-products of practice. As procedures become automatic, less attention is required to carry them out, so it is possible to do other things simultaneously, or at least do other things more comfortably. By this stage, student performance of the skill is rapid and smooth. The student devotes much less deliberate attention to performance, and may be able to carry on a conversation or perform other tasks while performing the skill. The student makes far fewer adjustments during his or her performance and these adjustments tend to be small. The student may no longer be able to remember the individual steps in the procedure, or explain how to perform the skill.
For example, the student smoothly increases power, back pressure on the yoke, and trim as a turn is entered. During the turn, the instructor questions the student on an unrelated topic. The student answers the questions, while making two small adjustments in pitch and trim, and then rolls out of the turn with the altimeter centered on the target altitude. Noting the dramatically improved performance, the instructor asks “What are you doing differently?” The student seems unsure and says, “I have developed a feel for it.”
Knowledge of Results
In learning some simple skills, students can discover their own errors quite easily. In other cases, such as learning complex aircraft maintenance skills, ﬂight maneuvers, or ﬂight crew duties, mistakes are not always apparent. A student may know that something is wrong, but not know how to correct it. In any case, the instructor provides a helpful and often critical function in making certain that the students are aware of their progress. It is perhaps as important for students to know when they are right as when they are wrong. They should be told as soon after the performance as possible, and should not be allowed to practice mistakes. It is more difﬁcult to unlearn a mistake, and then learn the skill correctly, than to learn correctly in the ﬁrst place. One way to make students aware of their progress is to repeat a demonstration or example and to show them the standards their performance must ultimately meet.
How To Develop Skills
Theories about how a skill evolves from the awkward and deliberate performance associated with the cognitive stage to the smooth and steady-handed performance of the automatic response stage have one thing in common: progress appears to depend on repeated practice. Making progress toward automating a skill seems to be largely a matter of performing the skill over and over again. In skill learning, the ﬁrst trials are slow and coordination is lacking. Mistakes are frequent, but each trial provides clues for improvement in subsequent trials. The student modiﬁes different aspects of the skill such as how to hold the yoke or weld correctly.
How long does it take to become proﬁcient at a skill? Studies of skill learning have demonstrated that progress tends to follow what is known as a power law of practice. This law simply states that the speed of performance of a task improves as a power of the number of times that the task is performed. The logarithm of the reaction time for a particular task decreases linearly with the logarithm of the number of practice trials taken. Qualitatively, the law simply says that practice improves performance.
Figure 2-17. Students will probably experience a learning plateau at some point in their training.
The graph in Figure 2-17 shows how the power law of practice relates the time required to perform a skill to the number of times the skill has been practiced. While it is impossible to predict how many practice trials a student will recquire to develop a skill to maturity, the general shape of the power law of practice offers some clues. Learning progress proceeds at a fast pace in the beginning (when there is ample room for improvement) and tends to slow down as performance becomes more skilled. In later stages of learning, improvement is more gradual. Once the curve levels off, it may stay level for a signiﬁcant period of time. Further improvement may even seem unlikely. This is called a learning plateau.
Learning plateaus are a normal part of the learning process and tend to be temporary, but instructors and students should be prepared for them. A learning plateau may signify any number of conditions. For example, the student may have reached capability limits, may be consolidating levels of skill, interest may have waned, or the student may need a more efﬁcient method for increasing progress. Instructors themselves can bring on a learning plateau by overpractice. After repeating any task three or four times, give it a break to avoid causing a learning plateau. Keep in mind that the apparent lack of increasing proﬁciency does not necessarily mean that learning has ceased. The point is that, in learning motor skills, a leveling off process, or plateau, is normal and should be expected after an initial period of rapid improvement. The instructor should prepare the student for this situation to avert discouragement. If the student is aware of this learning plateau, frustration may be minimized.
Instructors can help students who fall into a learning plateau by moving the student to a different place in the curriculum and giving the current task a break. Instructors should also be aware that they can bring on a learning plateau by over-practice. Learning plateau problems can sometimes be alleviated also by the instructor better explaining the lesson, the reason for the lesson, and how it applies to the student.
Types of Practice
Once a student learns the skill, it is important to continue some practice to improve retention, but the power law of practice raises the question of whether or not there is a point at which continued practice no longer leads to improvement. Since athletic coaches, among others, are very interested in maximizing performance, much research has been done on the subject. Within the last few years, research has shown that how practice is structured makes an important impact on how well people retain what they have learned.
There are three types of practice, each of which yields particular results in acquiring skills: deliberate, blocked, and random.
In order for a student to gain skill knowledge and learn how to perform the skill on the automatic level, a student must engage in deliberate practice. This practice is aimed at a particular goal. During deliberate practice, the student practices speciﬁc areas for improvement and receives speciﬁc feedback after practice. The feedback points out discrepancies between the actual performance and the performance goal sought. During deliberate practice, a student focuses on eliminating these discrepancies. [Figure 2-18]
Figure 2-18. A student exhibits deliberate practice by plotting courses for his next training flight.
Studies of skill learning suggest a student achieves better results if distractions are avoided during deliberate practice. When feedback is needed to correct student performance, it should be brief and explicit. Examples of individual skills for pilots are landings, stalls, steep turns, and procedure ﬂows. Examples for maintenance technicians are correct installation of piston rings on a reciprocating engine, setting timing on an aircraft engine, and installing a tach generator.
Unlike the acquisition of knowledge, skill learning does not beneﬁt from the instructor introducing the student to new ideas or prompting the student to think about old ones in different ways. On the other hand, instructors should not confuse distractions during skill learning with the legitimate use of distractions to help a student learn how to manage his or her attention while coordinating several tasks that have been mastered to some degree.
Blocked practice is practicing the same drill until the movement becomes automatic. Doing the same task over and over leads to better short-term performance, but poorer long-term learning. It tends to fool not only the student but the instructor into thinking the skills have been well learned. While blocked practice enhances current performance, it does not improve either concept learning or retrieval from long-term memory. [Figure 2-19]
Figure 2-19. Pilot practices cross-wind landings repeatedly to improve performance.
Random practice mixes up the skills to be acquired throughout the practice session. This type of practice leads to better retention because by performing a series of separate skills in a random order, the student starts to recognize the similarities and differences of each skill which makes it more meaningful. The learner also is able to store the skill more effectively in the long-term memory. Students are then required to retrieve steps and parameters from long-term memory which helps students recognize patterns between tasks.
Blocked practice performance scores well during the actual practice when compared to random practice performance. But on a test given the next day, random practice does better than blocked practice. For long-term retention of aviation knowledge, the instructor who uses well-written SBT which encourages random practice and leads to better retention of information.
How much practice is needed to attain proficiency? In planning for student skill acquisition, a primary consideration is the length of time devoted to practice. A beginning student reaches a point where additional practice is not only unproductive, but may even be harmful. When this point is reached, errors increase, and motivation declines. As a student gains experience, longer periods of practice are proﬁtable.
Another consideration is the problem of whether to divide the practice period. Perhaps even the related instruction should be broken down into segments, or it may be advantageous to plan one continuous, integrated sequence. The answer depends on the nature of the skill. Some skills are composed of closely related steps, each dependent on the preceding one. Learning to pack a parachute is a good example. Other skills are composed of related subgroups of skills. Learning to overhaul an aircraft engine is a good example.
One way to structure practice to get the most from learning is to expose the student to the same knowledge and skill in different contexts. For example, after practicing the short ﬁeld landing in the aircraft, return to the classroom and rehearse the procedure using the toy airplane. Then, watch a video that shows a variety of back-to-back landings and have the student describe what went right and what went wrong. Each of these learning methods gives the student the chance practice the maneuver while adding new perceptions and insights to his or her skill base.
Evaluation Versus Critique
In the initial stages of skill acquisition, practical suggestions are more valuable to the student than a grade. Early evaluation is usually teacher oriented. It provides a check on teaching effectiveness, can be used to predict eventual student learning proﬁciency, and can help the teacher locate special problem areas. The observations on which the evaluations are based also can identify the student’s strengths and weaknesses, a prerequisite for making constructive criticism. For additional information, refer to Chapter 5, Assessment.
As a student practices a skill, it is important he or she perform the skill correctly and that the skill being practiced is one that needs to be developed to maturity. An instructor ensures a skill is practiced correctly by monitoring the practice and providing feedback about the skill development. The student proﬁts by having someone watch the performance and provide constructive criticism to help eliminate errors. Providing compliments on aspects of the skill that were performed correctly help keep the evaluation positive. Allowing the student to critique his or her performance enhances student-centered training.
Instructors should note students can develop deviations from the intended method of performance at any stage of skill acquisition.
Overlearning of Knowledge
Overlearning is the continued study of a skill after initial proﬁciency has been achieved. Practice proceeds beyond the point at which the act can be performed with the required degree of excellence. The phenomenon of overlearning sometimes occurs when knowledge used frequently begins to take on the properties of a skill. For example, a student’s everyday knowledge about weight-and-balance concepts tends to center on the routine use of familiar charts found in the aircraft. Eventually, the student’s performance is characterized less by an understanding of weight-and-balance concepts, and more by an automatic process in which rows and columns of familiar charts give desired numbers.
In some cases, the overlearning of knowledge has the advantage of making application of knowledge more streamlined and efﬁcient. In other cases, the development of automated routines can lead to problems. For example, a verbal checklist procedure becomes so automatic that a streamlined recitation of checklist items becomes decoupled from the thoughts and actions the checklist items are intended to trigger. In this case, the pilot or mechanic may not stop to consider each item.
The development of automated skills can impede further learning or lead to forgetting general knowledge. In one study, student pilots and ﬂight instructors were asked to solve weight-and-balance problems using charts taken from two different aircraft: (1) a small single-engine airplane they ﬂew on a daily basis and (2) a different small single-engine airplane in which they had no experience. Test scores were surprisingly low when the charts for the unfamiliar airplane were used, and this was as true for instructors as it was for students. The results suggest pilots had focused on developing streamlined, automatic procedures tuned to the details of the familiar aircraft charts while their ability to use their understanding of overall weight-and-balance concepts seemed to have diminished.
Instructors must remain aware of skills students develop as a result of overlearning and help make sure that their actions continue to be accompanied by a use of their underlying knowledge. As a student progresses, the key difference between knowledge and skill becomes apparent. Memorized facts about a topic that once supported the beginner’s awkward performance of the skill tend to develop into deeper understanding. Skill acquisition involves learning many individual steps that eventually meld into a seemingly continuous automated process, at which point the student has entered the procedural knowledge realm, and may no longer be consciously aware of the individual steps.
Application of Skill
The ﬁnal and critical question is “Can the student use what has been learned?” It is not uncommon to ﬁnd that students devote weeks and months in school learning new abilities, and then fail to apply these abilities on the job. To solve this problem, two conditions must be present. First, the student must learn the skill so well that it becomes easy, even habitual. Second, the student must recognize the types of situations where it is appropriate to use the skill. This second condition involves the question of transfer of learning, which is discussed later in this chapter.
Summary of Instructor Actions
To help students acquire skills, the instructor should:
Explain that the key to acquiring and improving any skill is continued practice.
Monitor student practice of skills and provide immediate feedback.
Avoid conversation and other distractions when students are practicing individual skills.
Explain that learning plateaus are common and that continued practice leads to continued improvement.
Putting It All Together
Many skills are learned before a student can ﬂy an airplane or a maintenance student can rebuild an aircraft engine. Just as practicing scales is a fundamental part of learning to play the piano, the student does not “make music” until the ability to combine the notes in a variety of ways is acquired. For the student pilot or technician, practicing speciﬁc skills is essential, but ﬂying a cross-country trip or repairing a collapsed landing gear requires “putting it all together” in the right way to achieve success.
The following section looks at the challenge of learning to perform several tasks at once, dealing with distractions and interruptions, overcoming problems with ﬁxation and inattention. It also describes the beneﬁts of using realistic training scenarios to develop these abilities.
Multitasking is the simultaneous execution of two or more tasks. A hallmark of the proﬁcient pilot or mechanic is the ability to multitask. In aviation, multitasking involves two different abilities: attention switching and simultaneous performance. It is useful to distinguish between the two types of multitasking because developing both types of abilities is an important part of aviation training.
Continuously switching attention back and forth between two or more tasks is attention switching. For example, when Beverly uses a checklist to perform a preﬂight inspection, she must continuously switch her attention between the checklist and the equipment she is inspecting. She looks at the checklist to retrieve the next step in the procedure, and then looks at the equipment to perform the step.
For many kinds of tasks, attention switching is the only way to accomplish multitasking. For example, it is generally impossible to look at two different things at the same time. The area of focused vision (called the fovea) is only a few degrees in span and can only be directed to one location at a time. Similarly, people cannot listen to two conversations at the same time. While both conversations fall upon the ears at once, people must devote their attention to the comprehension of one, to the exclusion of the other.
Psychologists sometimes refer to these limiting features of human information-processing capabilities as bottlenecks. For example, people have bottlenecks within the individual perceptual channels of hearing and seeing. Another important bottleneck becomes apparent when people attempt to process the information perceived or retrieved from memories. Indeed, it seems impossible to think about two different things at the same time.
Performing several tasks at once, or simultaneous performance, is the second type of multitasking. [Figure 2-20] This type of multitasking becomes possible when no bottlenecks are present and when one or more of the tasks being performed are skills developed to the point of being automatic. For example, the experienced instrument pilot is able to perform basic attitude instrument ﬂying while communicating with ATC. For these pilots, scanning instruments and responding to minor attitude deviations with small control inputs has become automatic. The attentional resources of the pilot are free to devote to thinking and talking about other topics.
Figure 2-20. A pilot is required to perform several tasks at once during approach and landings.
It is important to note that the ability to simultaneously perform tasks is a fragile phenomenon. For example, suppose Beverly is performing the basic attitude control task and communicating with ATC when she suddenly encounters turbulence. The attitude control task quickly increases in difﬁculty and begins to require more and more deliberate attention. Her ability to perform both tasks simultaneously quickly degrades.
Learning To Multitask
Since doing several things at once is a natural part of aviation, instructors need to help students develop both types of multitasking abilities: attention switching and simultaneous performance. Before students are asked to perform several tasks at once, instructors should ensure that the student has devoted enough time to study and practice such that the individual tasks can be performed reasonably well in isolation.
Inexperience with an individual task can often hinder attempts to learn combinations of it and other tasks. For example, a student distracted by trying to interpret unfamiliar symbols on a sectional chart inadvertently deviates from assigned attitude or heading. An instructor recognizes the need to spend more time with these skills in isolation. In this case, there is nothing about the experience of controlling the aircraft that helps students better understand chart symbols.
Distractions and Interruptions
A distraction is an unexpected event that causes the student’s attention to be momentarily diverted. Students must learn to decide whether or not a distraction warrants further attention or action on their part. Once this has been decided, the students must either turn their attention back to what they were doing, or act on the distraction.
An interruption is an unexpected event for which the student voluntarily suspends performance of one task in order to complete a different one. Interruptions are a signiﬁcant source of errors and students must be made aware of the potential for errors caused by interruptions and develop procedures for dealing with them. A classic example is an interruption that occurs while a student is following the steps in a written procedure or checklist. The student puts down the checklist, deals with the interruption, and then returns to the procedure—but erroneously picks up at a later point in the procedure, omitting one or more steps.
Fixation and Inattention
Since human attention is limited in focus and highly prone to distraction, people are vulnerable to two other types of problems: ﬁxation and inattention.
Fixation occurs when a student becomes absorbed in performing one task to the exclusion of other tasks. Instructors see many examples of this in student performance. Beginning instrument pilots characteristically fixate on particular instruments, attempting to control one aspect of their performance while other aspects deteriorate. Fixation on a task is often a sign that the task has not received enough practice in isolation. That is, the student has not yet mastered the task well enough to perform it in addition to other tasks. Fixation can happen even when individual skills have been reasonably mastered, when students have not yet learned the importance of managing their own limited attentional resources.
Inattention occurs when a student fails to pay attention to a task that is important. Inattention is sometimes a natural by-product of ﬁxation. Students ﬁxate on one task and become too busy to attend to other tasks. Inattention also happens when students are not busy: attention may drift when they become bored or think that a task does not deserve their attention. In some cases, this type of inattention is difﬁcult to eliminate through training and practice. For example, it is well known that humans perform poorly when placed in the role of passive monitor. Many studies have shown how performance rapidly deteriorates when humans are asked to passively monitor gauges or the progress of an automated system such as a GPS navigation computer or autopilot. Furthermore, it seems that the more reliable the system becomes, the poorer the human performance becomes at the monitoring task. The ﬁrst line of defense against this type of inattention is to alert the student to the problem, and to help students develop habits that keep their attention focused.
How To Identify Fixation or Inattention Problems
One way for instructors to identify problems with ﬁxation and inattention is to try and follow where students look. To accomplish this, instructors can glance at a student’s eyes to try to determine where the student is looking. Students who appear to look at one instrument for an extended period of time might have a problem with ﬁxation. Students whose gaze is never directed toward engine instruments might have a problem with inattention.
The technique of following student eye movements is useful, but has limitations since looking in the same direction as the student is not the same as “seeing” what the student sees.
Research and practical experience have demonstrated the usefulness of practicing in realistic scenarios—ones that resemble the environment in which knowledge and skills are later used. Instructors must devise scenarios that allow students to practice what they have learned. This is challenging because different students need to practice different things at different times, and because different working environments present different practice opportunities.
What makes a good scenario? A good scenario:
Has a clear set of objective.
Is tailored to the needs of the student.
Capitalizes on the nuances of the local environment.
For example, Bill is introducing Beverly to a low-fuel emergency. His objective at this early stage is to simply enable Beverly to recall the sorts of actions that are appropriate for a low-fuel emergency. He decides to use the classroom environment as a ﬁrst practice scenario. He asks Beverly about what sorts of actions she might take if such an event would occur. She has some good ideas but he asks her to think more about before her next lesson. On her next lesson he gives her the same exercise. This time her answers are consistent and insightful. Bill decides that this scenario has served its purpose and moves on.
During their next ﬂight, Bill’s objective is having Beverly recall and carry out the steps that she was able to cite in the classroom. As they arrive at their home airport, he presents Beverly with a low-fuel scenario. He notes that she remembers much of what she was able to recall in the classroom, but amidst the excitement, has forgotten a few things. He uses the same scenario at a different airport on their next ﬂight, and she performs admirably.
Later in her training, Bill’s next objective is to enable her to recall and perform the emergency steps in concert with other piloting duties. They depart on a cross-country ﬂight from a populated area to a remote area. While en route, Bill presents Beverly with a low-fuel emergency scenario knowing that there is only one airport nearby and that it is not easy to spot. She successfully uses her available navigational resources to locate and arrive at the airport. Upon returning home, Bill attempts to generalize her new abilities and put yet a different spin on the same problem. He presents the low-fuel scenario, taking advantage of the fact that there are eight nearby airports. All of the airports are in plain view, and she must choose one.
Each of these scenarios taught Beverly something she needed to learn next, and made good use of the surroundings and available circumstances. As these examples illustrate, there is no list of “canned” scenarios that can be used for all students. Instructors must learn to devise their own scenarios by considering what each student needs to practice, and exploiting features of the local environment that allow them to do it.
The Learning Route to Expertise
What does it take to successfully orchestrate all of the knowledge and skills the student has learned into what instructors, evaluators, and other pilots and mechanics would regard as true expertise? All evidence seems to point once again to the idea of practice. Just as the perfection of an individual skill seems to rely on repeated practice, so does the combination of knowledge and skills that make up our abilities to do the real-world job of pilot or mechanic.
How much practice does it take to become a true expert? In a study of expert performers in ﬁelds ranging from science to music to chess, one psychologist found that no performer had reached true expertise without having invested at least ten years of practice in his or her ﬁeld. Experts have been found to use two tools to help them gain expertise in their ﬁeld: cognitive strategies and problem-solving tactics.
The idea of cognitive strategies emerged over 50 years ago in the context of human information processing theory. Cognitive strategies refer to the knowledge of procedures or knowledge about how to do something in contrast with the knowledge of facts. They use the mind to solve a problem or complete a task and provide a structure for learning that actively promotes the comprehension and retention of knowledge. A cognitive strategy helps the learner develop internal procedures that enable him or her to perform higher level operations.
As students acquire experience, they develop their own strategies for dealing with problems that arise frequently. For example, a student develops the following strategy for avoiding inadvertent ﬂight into instrument meteorological conditions (IMC) at night. He or she checks the weather prior to departure, obtains updates on the weather every hour, and plans to divert to an alternate destination at the ﬁrst suspicion of unexpected weather ahead.
One approach to helping students develop cognitive strategies is to study and identify the strategies that experts use and then teach these strategies to the students. Expert strategies were identiﬁed by researchers who presented experts with problems to solve and asked them to think aloud as they attempted to solve the problems. These cognitive strategies can be taught to students, usually with successful results.
Problem-solving tactics are speciﬁc actions intended to get a particular result, and this type of knowledge represents the most targeted knowledge in the expert’s arsenal. For example, a student notices how easy it is to make a mistake with a takeoff distance chart after using it several times. She notices her ﬁnger drifts upward or downward when sliding it across a row of numbers on the chart, sometimes landing on the wrong number. The student formulates several tactics to ensure she obtains the correct ﬁgures: (1) work slowly and deliberately, (2) use a ruler, and (3) double-check the work.
But even the experts had to practice. In a study of violinists at a music academy in Berlin, researchers compared the “best” students to those who were regarded as merely “very good.” Using estimates of how many total hours each student had spent practicing during his or her lifetime, the researchers found that the best violinists had spent an average of 7,000 hours practicing, while the very good violinists had logged about 5,000 hours. The scientiﬁc study of expertise reiterates the adage: “Practice makes perfect.”
Awareness of Existence of Unknowns
An important aspect of an expert’s knowledge is an awareness of what he or she does not know. This is not always the case with a student. It’s important that an instructor be aware of situations in which students have acquired “book” knowledge, but not yet acquired the more in-depth understanding that comes from association and experience. For example, after acquiring substantial knowledge of a single-engine training aircraft, students should understand that a four-seat aircraft by the same manufacturer should be approached with caution and not overconﬁdence.
Summary of Instructor Actions
To help students exercise their knowledge and skills in a concerted fashion, the instructor should:
Explain the two types of multitasking and give examples of each type.
Ensure that individual skills are reasonably well-practiced before asking students to perform several tasks at once.
Teach students how to deal with distractions and interruptions and provide them with opportunities to practice.
Point out ﬁxation and inattention when it occurs.
Devise scenarios that allow students to use their knowledge and skill to solve realistic problems and make decisions.
Explain to the student that continued practice with the goal of improving leads to continued improvement.
Errors are a natural part of human performance. Beginners, as well as the most highly skilled experts, are vulnerable to error, and this is perhaps the most important thing to understand about error. To believe people can eliminate errors from their performance is to commit the biggest error of all. Instructors and students alike should be prepared for occasional errors by learning about common kinds of errors, how errors can be minimized, how to learn from errors, and how to recover from errors when they are made.
Kinds of Error
There are two kinds of error: slip and mistake.
A slip occurs when a person plans to do one thing, but then inadvertently does something else. Slips are errors of action. Slips can take on a variety of different forms. One of the most common forms of slips is to simply neglect to do something. Other forms of slips occur when people confuse two things that are similar. Accidentally using a manual that is similar to the one really needed is an example of this type of slip.
Other forms of slips happen when someone is asked to perform a routine procedure in a slightly different way. For example, Beverly has been assigned runway 30 for many days in a row. This morning she approaches to land and ATC assigns runway 12 instead. As she approaches the trafﬁc pattern, she turns to enter the pattern for runway 30 out of habit.
Time pressure is another common source of slips. Studies of people performing a variety of tasks demonstrated a phenomenon called the speed-accuracy tradeoff. The more hurried one’s work becomes the more slips one is likely to make.
A mistake occurs when a person plans to do the wrong thing and is successful. Mistakes are errors of thought. Mistakes are sometimes the result of gaps or misconceptions in the student’s understanding. One type of mistake happens when a student formulates an understanding of a phenomenon and then later encounters a situation that shows how this understanding was incorrect or incomplete. For example, overly simplistic understanding of weather frequently leads inexperienced students into situations that are unexpected.
Experts are not immune to making mistakes, which sometimes arise from the way an expert draws upon knowledge of familiar problems and responds to them using familiar solutions. [Figure 2-21] Mistakes can occur when the expert categorizes a particular case incorrectly. For example, an experienced pilot may become accustomed to ignoring nuisance alerts issued by his trafﬁc alerting system when approaching his home airport, as many aircraft on the ground turn on their transponders prior to takeoff. One night, he ignores an alert that was generated not by an aircraft on the ground, but rather by another aircraft that has turned in front of him on ﬁnal approach.
Figure 2-21. Other mistakes arise under pressure. For example, a technician or pilot might perform a cursory inspection of an aircraft to save time, only to have a problem manifest itself later.
Although it is impossible to eliminate errors entirely, there are ways to reduce them, as described in the following paragraphs.
Learning and Practicing
The ﬁrst line of defense against errors is learning and practice. Higher levels of knowledge and skill are associated with a lower frequency and magnitude of error.
Errors can often be reduced by working deliberately at a comfortable pace. Hurrying does not achieve the same results as faster performance that is gained by increasing one’s skill through continued practice.
Checking for Errors
Another way to help avoid errors is to look actively for evidence of them. Many tasks in aviation offer a means of checking work. Students should be encouraged to look for new ways of checking their work.
Errors are reduced when visible reminders are present and actively used. Checklists and other published procedures are examples of reminders. Many aircraft instruments such as altimeters offer bugs that can be used to remind the pilot about assigned altitudes, airspeeds, headings, and courses. Mechanics and pilots alike can use notepads to jot down reminders or information that must otherwise be committed to memory.
The use of standardized procedures for routine tasks is widely known to help reduce error. Even when a checklist procedure is unavailable or impractical, students can help reduce the occurrence of error by adopting standardized procedures.
Another line of defense against errors is to raise one’s awareness when operating in conditions under which errors are known to happen (e.g., changes in routine, time pressure), or in conditions under which defenses against errors have been compromised (e.g., fatigue, lack of recent practice).
Given that the occasional error is inevitable, it is a worthwhile exercise to practice recovering from commonly made errors, or those that pose serious consequences. All ﬂight students are required to learn and practice a lost procedure to ensure that they can recover from the situation in which they have lost their way. It is useful to devote the same sort of preparation to other common student errors.
Learning From Error
Error can be a valuable learning resource. Students naturally make errors, which instructors can utilize to help students learn while being careful not to let the student practice doing the wrong thing. When a student makes an error, it is useful to ask the student to consider why the error happened, and what could be done differently to prevent the error from happening again in the future. In some cases, errors are slips that simply reveal the need for more practice. In other cases, errors point to aspects of student methods or habits that might be improved. For example, beginning instrument ﬂight students commonly make errors when managing two communications radios, each with an active and standby frequency. When the same students learn to use each radio for a speciﬁc purpose (e.g., ATIS, ground, tower frequencies), error rates often drop quickly.
Instructors and students should be aware of a natural human tendency to resist learning from errors. That is, there is a tendency to “explain away” errors, dismissing them as one-time events that will likely never happen again. The same phenomenon occurs when observing errors made by others. Reading an accident or incident report, it is easy to spot where a pilot or mechanic made an error and regard the error as something that could never happen to the reader. It is important to note that this type of bias is not necessarily the result of ego or overconﬁdence; rather, it is something to which we are all susceptible. Psychologist Baruch Fischoff studied hindsight explanations given by people who were presented with descriptions of situations and their ultimate outcomes. When asked to provide explanations for events that had already occurred and for which the outcome was known, people explained that the outcomes were “obvious” and “predictable.” When the same events without the outcomes were presented to a second group, peoples’ prediction of the outcome was no better than chance guessing. The study nicely illustrates the popular adage that “hindsight is 20/20.”
Summary of Instructor Actions
To help students learn from errors they make and be prepared for them in the future, an instructor should:
Explain that pilots and mechanics at all levels of skill and experience make occasional errors.
Explain that the magnitude and frequency of errors tend to decrease as skill and experience increases.
Explain the difference between slips and mistakes and provide examples of each.
Explain ways in which the student can help minimize errors.
Allow the student to practice recovering from common errors.
Point out errors when they occur and ask the student to explain why they occurred.
As deﬁned in chapter 1, motivation is the reason one acts or behaves in a certain way and lies at the heart of goals. A goal is the object of a person’s effort. Motivation prompts students to engage in hard work and affects student success. Being smart or coordinated seldom guarantees success, but motivation routinely propels students to the top. An important part of an aviation instructor’s job is to discover what motivates each student and to use this information to encourage him or her to work hard.
Motivation is probably the dominant force that governs the student’s progress and ability to learn and can be used to advantage by the instructor. Motivation comes in many guises. It may be negative or positive. Negative motivation may engender fear, for example. While negative motivation may be useful in certain situations, characteristically it is not as effective in promoting efﬁcient learning as positive motivation. [Figure 2-22] Positive motivation is provided by the promise or achievement of rewards. These rewards may be personal or social, they may involve ﬁnancial gain, satisfaction of the self-concept, personal gain, or public recognition.
Figure 2-22. Insecure and unpleasant training situations inhibit learning.
Motivation may be tangible or intangible. Students seeking intangible rewards are motivated by the desires for personal comfort and security, group approval, and the achievement of a favorable self-image. The desire for personal comfort and security is a form of motivation which instructors often forget. All students want secure, pleasant conditions and a safe environment. If they recognize that what they are learning may promote these objectives, their attention is easier to attract and hold. Insecure and unpleasant training situations inhibit learning. Students also want a tangible return for their efforts. For motivation to be effective on this level, students must believe that their efforts are suitably rewarded. These rewards must be constantly apparent to the student during instruction, whether they are to be ﬁnancial, self-esteem, or public recognition.
The tangible rewards of aviation are not always obvious during training. Traditional syllabi often contain lessons with objectives that are not immediately obvious to the student. These lessons may pay dividends during later instruction, a fact the student may not appreciate and resulting in less learning than if the student could relate all objectives to an operational need (law of readiness). The instructor should ensure that the student is aware of those applications which are not immediately apparent. To reduce this issue, the instructor should develop appropriate scenarios that contain the elements to be practiced.
Everyone wants to avoid pain and injury. Students normally are eager to learn operations or procedures that help prevent injury or loss of life. This is especially true when the student knows that the ability to make timely decisions, or to act correctly in an emergency, is based on sound principles.
The attractive features of the activity to be learned also can be a strong motivational factor. Students are anxious to learn skills that may be used to their advantage. If they understand that each task is useful in preparing for future activities, they are more willing to pursue it.
Another strong motivating force is group approval. Every person wants the approval of peers and superiors. Interest can be stimulated and maintained by building on this natural desire. Most students enjoy the feeling of belonging to a group and are interested in accomplishment, which gives them prestige among their fellow students.
Every person seeks to establish a favorable self-image. In certain instances, this self-image may be submerged in feelings of insecurity or despondency. Fortunately, most people engaged in a task believe that success is possible under the right combination of circumstances and good fortune. This belief can be a powerful motivating force for students. An instructor can effectively foster this motivation by the introduction of perceptions that are solidly based on previously learned factual information easily recognized by the student. Each additional block of learning should help formulate insight, contributing to the ultimate training goals, and promoting student conﬁdence in the overall training program. At the same time, it helps the student develop a favorable self-image. As this conﬁrmation progresses and conﬁdence increases, advancement is more rapid and motivation is strengthened.
Positive motivation is essential to true learning. Negative motivation in the form of reproofs or threats should be avoided with all but the most overconﬁdent and impulsive students. Slumps in learning are often due to declining motivation. Motivation does not remain at a uniformly high level. It may be affected by outside inﬂuences, such as physical or mental disturbances or inadequate instruction. The instructor should strive to maintain motivation at the highest possible level. In addition, the instructor should be alert to detect and counter any lapses in motivation.
Where Does the Motivation To Learn Come From?
Motivation to learn can come from many sources. Some students have a fundamental interest in aviation and experience sheer fascination with aircraft or with the experience of ﬂight. Other students may decide that aviation provides an opportunity to develop a wide variety of technical, physical, communication, and problem-solving abilities. Some see aviation as a way to boost their self-image or ego. Other students are motivated by tradition and wish to follow in the footsteps of a relative or close friend. Some students are motivated to pursue aviation training because it offers a promising career. To others, aviation offers prestige or acceptance within social groups. Some may think that aviation offers fun and excitement or simply a more convenient form of transportation. All of these sources of motivation have one thing in common: they all offer some type of reward in exchange for performing the hard work.
Teaching the adult learner was discussed in chapter 1, but aviation instructors should keep in mind that adult learners who are motivated to seek out a learning experience do so primarily because they have a use for the knowledge or skill being sought. Learning is a means to an end, not an end in itself. Based on this, it is important instructors determine why a student enrolled in the course. Based on preference and/or class size, an instructor can conduct a brief personal interview with the student or have the student complete a student information form. [Figure 2-23] Asking questions such as “Why are you taking this course?” or “How do you plan to use the information you learn in this course?” may be all that is necessary.
Figure 2-23. An instructor’s first task with a student is to learn about personal goals to help him or her stay motivated to learn.
A short questionnaire can be helpful in gathering additional student background information. For example, it is helpful to know a student’s familiarity with the subject matter. Questions such as “Have you ever taken a course in aircraft maintenance?” or “Have you ever ﬂown a small airplane?” or “Have you had any on-the-job training in avionics?” should garner the type of information needed.
A short questionnaire also offers an instructor the chance to discover how the student learns best (small groups, independent study, etc.). Another possible way to gather information about a student is to have him or her write a brief autobiography which includes any experience with the subjects being taught. However an instructor gathers information about students, the information helps the instructor allow for not only personal learning goals for the course, but also the goals and motivations of the students, their background in aviation training, as well as their learning preferences. An instructor armed with this information can make the learning experience beneﬁcial to all involved.
Motivation is generally not something that can be transferred from one person to another. Instructors must become skillful at recognizing problems with motivation and at encouraging students to continue to do their best.
Positive feedback encourages students. Practice positive feedback frequently by:
Praising incremental successes during training.
Relating daily accomplishments to lesson objectives.
Commenting favorably on student progress and level ability.
For example, as the student progresses through training, remark on the milestones. When a student ﬁrst performs a task alone, congratulate him or her on having learned it.
When that same skill reaches an intermediate level, point out that the student’s performance is almost consistent with the requirements of the PTS. When performance is equal to the PTS requirements, comment favorably on the skill acquisition. When student performance exceeds PTS requirements, point out what a beneﬁt this will be when the student must perform under pressure during a practical test or on the job.
Presenting New Challenges
With each declaration of success, be sure to present students with the next challenge. For example, when a student begins to perform a skill consistently to PTS requirements, challenge him or her to continue to improve it so the skill can be performed under pressure or when distracted. Instructors can also present new challenges by presenting the student with new problems or situations.
Drops in Motivation
Instructors must be prepared to deal with a number of circumstances in which motivation levels drop. It is natural for motivation to wane somewhat after the initial excitement of the student’s ﬁrst days of training, or between major training events such as solo, evaluations, or practical tests. Drops in motivation appear in several different ways. Students may come to lessons unprepared or give the general sense that aviation training is no longer a priority. During these times, it is often helpful to remind students of their own stated goals for seeking aviation training.
Learning plateaus are a common source of frustration, discouragement, and decreased student motivation. A ﬁrst line of defense against this situation is to explain that learning seldom proceeds at a constant pace—no student climbs the ladder of success by exactly one rung per day. Students should be encouraged to continue to work hard and be reassured that results will follow.
Summary of Instructor Actions
To ensure that students continue to work hard, the instructor should:
Ask new students about their aviation training goals.
Reward incremental successes in learning.
Present new challenges.
Occasionally remind students about their own stated goals for aviation training.
Assure students that learning plateaus are normal and that improvement will resume with continued effort.
Memory is the vital link between the student learning/retaining information and the cognitive process of applying what is learned. It is the ability of people and other organisms to encode (initial perception and registration of information), store (retention of encoded information over time), and retrieve (processes involved in using stored information) information. [Figure 2-24] When a person successfully recalls a past experience (or skill), information about the experience has been encoded, stored, and retrieved.
Figure 2-24. Information processing within the sensory register, working on short-term memory, and long-term memory includes complex coding, sorting, storing, and recall functions.
Although there is no universal agreement of how memory works, a widely accepted model has three components: sensory memory, short-term memory, and long-term memory.
Sensory memory is the part of the memory system that receives initial stimuli from the environment and processes them according to the individual’s preconceived concept of what is important. Other factors can inﬂuence the reception of information by sensory memory. For example, if the input is dramatic and impacts more than one of the ﬁve senses, that information is more likely to make an impression. The sensory memory processes stimuli from the environment within seconds, discards what is considered extraneous, and processes what is determined by the individual to be relevant. This is a selective process where the sensory register is set to recognize certain stimuli and immediately transmit them to the short-term memory (STM) for action. The process is called precoding. An example of sensory precoding is recognition of a ﬁre alarm. No matter what is happening at the time, when the sensory register detects a ﬁre alarm, the working memory is immediately made aware of the alarm and preset responses begin to take place. Sensory memory is capable of retaining information for only a very short period of time and within seconds the relevant information is passed to the STM.
Short-Term Memory (STM)
Short-term memory is the part of the memory system where information is stored for roughly 30 seconds, after which it may rapidly fade or be consolidated into long-term memory, depending on the individual’s priorities. Several common steps help retention in STM. These include rehearsal or repetition of the information and sorting or categorization into systematic chunks. The sorting process is usually called coding or chunking. A key limitation of STM is that it takes 5–10 seconds to properly code information and if the coding process is interrupted, that information is easily lost since it is stored for only 30 seconds. The goal of the STM is to put the information to immediate use.
The STM is not only time limited, it also has limited capacity, usually about seven bits or chunks of information. A seven-digit telephone number is an example. As indicated, the time limitation may be overcome by rehearsal. This means learning the information by a rote memorization process. Of course, rote memorization is subject to imperfections in both the duration of recall and in its accuracy. The coding process is more useful in a learning situation. In addition, the coding process may involve recoding to adjust the information to individual experiences. This is when actual learning begins to take place. Therefore, recoding may be described as a process of relating incoming information to concepts or knowledge already in memory.
Brain research has led to the conclusion that STM resembles the control tower of a major airport and is responsible for scheduling and coordinating all incoming and outgoing ﬂights. STM has three basic operations: iconic memory, acoustic memory, and working memory. Iconic memory is the brief sensory memory of visual images. Acoustic memory is the encoded memory of a brief sound memory or the ability to hold sounds in STM. Of the two, acoustic memory can be held longer than iconic memory. Working memory is an active process to keep information until it is put to use (think of a phone number repeated until used). It is useful in remembering a spoken sentence or a string of digits.
Also called “scratch-pad” memory, working memory is of short duration and has limited capacity. It simultaneously stores and manipulates information. The goal of the working memory is not really to move the information from STM to long-term memory (LTM), but merely put the information to immediate use.
STM retention makes information available long enough for it to be rehearsed. For example, if the learner repeats the number to himself, it can be transferred to some sort of longer term storage. To retain information for extended periods of time, it must be transferred from STM to LTM. This process involves encoding or consolidation of information into LTM where it can then be retrieved.
Long-Term Memory (LTM)
Long-term memory (LTM) is relatively permanent storage of unlimited information and it is possible for memories in LTM to remain there for a lifetime. What is stored in LTM affects a person’s perceptions of the world and affects what information in the environment is noticed. Information that passes from STM to LTM typically has some signiﬁcance attached to it. For example, imagine how difﬁcult it would be for a pilot to forget the ﬁrst day he or she soloed. This is a signiﬁcant day in any pilot’s training, so when the information was processed, signiﬁcance was attached to it, the information was deemed important, and it was transferred into LTM.
There must be other reasons information is transferred to LTM because the average human brain stores numerous insigniﬁcant facts. One explanation is repetition; people tend to remember things the more they are rehearsed. Information also ends up in LTM because it is somehow attached to something signiﬁcant. A man may remember the color of the dress his girlfriend was wearing on the day he proposed marriage to her. The color of the dress plays no important role, but is attached to the memory of proposing marriage.
For the stored information to be useful, some special effort must have been expended during the encoding or consolidation of information in STM. The encoding should provide meaning and connections between old and new information. If initial encoding is not properly accomplished, recall is distorted and it may be impossible. The more effective the encoding process, the easier the recall. However, it should be noted that the LTM is a reconstruction, not a pure recall of information or events. It is also subject to limitations, such as time, biases, and, in many cases, personal inaccuracies. This is why two people who view the same event often have totally different recollections. Memory also applies to psychomotor skills. For example, with practice, a tennis player may be able to serve a tennis ball at a high rate of speed and with accuracy. This may be accomplished with very little thought. For a pilot, the ability to instinctively perform certain maneuvers or tasks that require manual dexterity and precision, provides obvious beneﬁts. For example, it allows the pilot more time to concentrate on other essential duties such as navigation, communications with ATC facilities, and visual scanning for other aircraft.
Information in LTM is stored in interrelated networks of schemas which are the cognitive frameworks that help people organize and interpret information. Schemas guide recognition and understanding of new information by providing expectations about what should occur. Since LTM is organized into schemas, instructors must consciously look for ways to make training relevant and meaningful enough for the learner to transfer new information to LTM. This can be accomplished by activating existing schemas before presenting new information. For example, a brief review of the previous lesson via discussion, video, questions, etc.
Remembering What Has Been Learned
The moment people learn something new and add it to their repertoire of knowledge and skill, they are confronted with a second task: the task of remembering it. Remembering is a challenge because of a natural feature of human memory-forgetting. Forgetting is such an apparent part of human memory that it is often the ﬁrst thing that people think of when they bring up the topic of memory.
The following section discusses how remembering and forgetting happens in predictable ways that help keep human memories tuned to the demands of everyday life. Memories help people keep fresh precisely those things needed next, and let slip those things that have outlived their usefulness. Understanding the factors that determine what is remembered and what is forgotten helps instructor and student get the most from memory.
How Usage Affects Memory
The ability to retrieve knowledge or skills from memory is primarily related to two things: (1) how often that knowledge has been used in the past; and (2) how recently the knowledge has been used. These two factors are called frequency and recency of use. Frequency and recency can be present individually or in combination.
Frequency and recency—knowledge that enjoys both frequency and recency is likely to be retrieved easily and quickly. This is knowledge much used in the past that continues to be used in the present. This is the ideal situation for knowledge and skills that need to be used.
Frequency only—knowledge that has been used much in the past but that has not been used recently is vulnerable to being forgotten. This type of knowledge is likely to be retrieved slowly or not at all. To retrieve this knowledge and skill, some recent rehearsal or practice must be added in order to refresh the memory.
Recency only—knowledge that has been recently used but has not been used in the past is knowledge that has been recently acquired. This type of knowledge is particularly vulnerable to being forgotten since there is little to distinguish it from “throw away” knowledge, such as an hourly weather broadcast. To remember this knowledge requires a program of regular rehearsal to build up its frequency.
Forgetting, which refers to loss of a memory, typically involves a failure in memory retrieval. The failure may be due to the decay or overwriting of information which has been temporarily stored in STM, but generally forgetting refers to loss of information from LTM. The information is not lost, per se, it is somewhere in the person’s LTM, but he or she is not able to retrieve and remember it.
Why do people forget? Why don’t we remember everything? Do we need to remember everything? Most of the information people are exposed to each day has a short period of usefulness with little need to retain it. For example, why would anyone need to remember the details of an hourly weather broadcast ten years ago?
Thus, forgetting knowledge is not always a bad thing. For example, forgetting old information keeps new information up to date. Many theories on why people forget have been offered to explain the phenomenon, among them retrieval failure, fading, interference, and repression or suppression.
Retrieval failure is simply the inability to retrieve information, that tip-of-the-tongue phenomenon when a person knows the meaning of a word, or the answer to a question, but cannot retrieve it. It is also caused by the fact that sometimes people simply do not encode information well, and the information never makes it to LTM or is lost before it can attach itself to the LTM. This is sometimes referred to as failure to store.
The theory of fading or decay suggests that a person forgets information that is not used for an extended period of time, that it fades away or decays. It had been suggested that humans are physiologically preprogrammed to eventually erase data that no longer appears pertinent.
On the other hand, experimental studies show that a hypnotized person can describe speciﬁc details of an event, which normally is beyond recall. Apparently the memory is there, locked in the recesses of the mind. The difﬁculty is summoning the memory to consciousness or retrieving the link that leads to it.
Interference theory suggests that people forget something because a certain experience has overshadowed it, or that the learning of similar things has intervened. This theory might explain how the range of experiences after graduation from school causes a person to forget or to lose knowledge. In other words, new events displace many things that had been learned. From experiments, at least two conclusions about interference may be drawn. First, similar material seems to interfere with memory more than dissimilar material; and second, material not well learned suffers most from interference.
Repression or Suppression
Freudian psychology advances the view that some forgetting is caused by repression or suppression. In repression or suppression, a memory is pushed out of reach because the individual does not want to remember the feelings associated with it. Repression is an unconscious form of forgetting while suppression is a conscious form.
Forgetting information does not mean it is gone forever. Sometimes it is still there, just inaccessible.
Retention of Learning
Each of the theories of forgetting implies that when a person forgets something, it is not actually lost. Rather, it is simply unavailable for recall. The instructor’s problem is how to make certain that the student’s learning is readily available for recall. The following suggestions can help.
Teach thoroughly and with meaning. Material thoroughly learned is highly resistant to forgetting. This is suggested by experimental studies and it also was pointed out in the sections on skill learning. Meaningful learning builds patterns of relationships in the learner’s consciousness, which is one reason to conduct scenario-based training (SBT). In contrast, rote learning is superﬁcial and is not easily retained. Meaningful learning goes deep because it involves principles and concepts anchored in the student’s own experiences. The following discussion emphasizes ﬁve principles, which are generally accepted as having a direct application to remembering.
Praise Stimulates Remembering
Responses that give a pleasurable return tend to be repeated. Absence of praise or recognition tends to discourage, and any form of negativism in the acceptance of a response tends to make its recall less likely.
Recall Is Promoted by Association
As discussed earlier, each bit of information or action, which is associated with something to be learned, tends to facilitate its later recall by the student. Unique or disassociated facts tend to be forgotten unless they are of special interest or application.
Favorable Attitudes Aid Retention
People learn and remember only what they wish to know. Without motivation there is little chance for recall. The most effective motivation is based on positive or rewarding objectives.
Learning With All Senses Is Most Effective
Although people generally receive what is learned through the eyes and ears, other senses also contribute to most perceptions. When several senses respond together, a fuller understanding and greater chance of recall is achieved.
Meaningful Repetition Aids Recall
Each repetition gives the student an opportunity to gain a clearer and more accurate perception of the subject to be learned, but mere repetition does not guarantee retention. Practice provides an opportunity for learning, but does not cause it. Further, some research indicates that three or four repetitions provide the maximum effect, after which the rate of learning and probability of retention fall off rapidly.
Along with these ﬁve principles, there is a considerable amount of additional literature on retention of learning during a typical academic lesson. After the ﬁrst 10–15 minutes, the rate of retention drops signiﬁcantly until about the last 5–10 minutes when students wake up again. Students passively listening to a lecture have roughly a ﬁve percent retention rate over a 24-hour period, but students actively engaged in the learning process have a much higher retention. This clearly reiterates the point that active learning is superior to just listening.
A mnemonic uses a pattern of letters, ideas, visual images, or associations to assist in remembering information. It is a memory enhancing strategy that involves teaching learners to link new information to information they already know. Its chief value lies in helping learners recall information that needs to be recalled in a particular order by encoding difﬁcult-to-remember information in a way that makes it easier to remember. Research shows that providing students with memorization techniques improves their ability to recall information. Mnemonics include but are not limited to acronyms, acrostics, rhymes, or chaining.
Acronyms form a word from the ﬁrst letters of other words. For example, “AIM” is the acronym for Aeronautical Information Manual.
An acrostic is a poem, word puzzle, or other composition in which the ﬁrst letter of each line or word is a cue to the idea the learner wishes to remember. For example, Every Good Boy Does Fine is used to remember the order of the G-clef notes in music. An example of a useful aviation acrostic is the memory aid for one of the magnetic compass errors. The letters “ANDS” indicate:
Rhymes and melody are another way to remember information. Rhymes such as “In 1492, Columbus sailed the ocean blue.” Most children learn the alphabet using a familiar melody “Twinkle, Twinkle, Little Star.” A well-known mnemonic rhyme for remembering the days of the month is the familiar, “30 days hath September, April, June, and November...”
Chaining is used for ordered or unordered lists and consists of creating a story in which each word or idea that needs to be remembered cues the next idea.
Variations of the encoding process are practically endless. Developing a logical strategy for encoding information is a signiﬁcant step in the learning process.
Transfer of Learning
Transfer of learning is broadly deﬁned as the ability to apply knowledge or procedures learned in one context to new contexts. Learning occurs more quickly and the learner develops a deeper understanding of the task if he or she brings some knowledge or skills from previous learning. A positive transfer of learning occurs when the learner practices under a variety of conditions, underscoring again the value of SBT.
A distinction is commonly made between near and far transfer. Near transfer consists of transfer from initial learning that is situated in a given setting to ones that are closely related. Far transfer refers both to the ability to use what was learned in one setting to a different one as well as the ability to solve novel problems that share a common structure with the knowledge initially acquired. There is a third way to talk about transfer called generativity. In this context it means learners have the ability on their own to come up with novel solutions.
During a learning experience, things learned previously usually aid the student, but sometimes previous learning interferes with the current learning task. Consider the learning of two skills. If the learning of skill A helps to learn skill B, positive transfer occurs. If learning skill A hinders the learning of skill B, negative transfer occurs. For example, the practice of slow ﬂight (skill A) helps Beverly learn short-ﬁeld landings (skill B). However, practice in making a landing approach in an airplane (skill A) may hinder learning to make an approach in a helicopter (skill B). It should be noted that the learning of skill B might affect the retention or proﬁciency of skill A, either positively or negatively. While these processes may help substantiate the interference theory of forgetting, they are still concerned with the transfer of learning.
It is clear that some degree of transfer is involved in all learning. This is true because, except for certain inherent responses, all new learning is based upon previously learned experience. People interpret new things in terms of what they already know.
Many aspects of teaching proﬁt by this type of transfer, perhaps explaining why students of apparently equal ability have differing success in certain areas. Negative transfer may hinder the learning of some; positive transfer may help others. This points to a need to know a student’s past experience and what has already been learned. In lesson and syllabus development, instructors can plan for transfer by organizing course materials and individual lesson materials in a meaningful sequence. Each phase should help the student learn what is to follow.
The cause of transfer and exactly how it occurs is difﬁcult to determine, but no one disputes the fact that transfer occurs. For the instructor, the signiﬁcance of transference lies in the fact that the students can be helped to achieve it. The following suggestions are representative of what educational psychologists believe should be done:
Plan for transfer as a primary objective. As in all areas of teaching, the chance for success is increased if the instructor deliberately plans to achieve it.
Ensure that the students understand that what is learned can be applied to other situations. Prepare them to seek other applications.
Maintain high-order learning standards. Overlearning may be appropriate. The more thoroughly the students understand the material, the more likely they are to see its relationship to new situations. Avoid unnecessary rote learning, since it does not foster transfer.
Provide meaningful learning experiences that build student conﬁdence in their ability to transfer learning. This suggests activities that challenge them to exercise their imagination and ingenuity in applying their knowledge and skills.
Use instructional material that helps form valid concepts and generalizations. Use materials that make relationships clear.
The formation of correct habit patterns from the beginning of any learning process is essential to further learning and for correct performance after the completion of training. Remember, primacy is one of the fundamental principles of learning. Therefore, it is the instructor’s responsibility to insist on correct techniques and procedures from the outset of training to provide proper habit patterns. It is much easier to foster proper habits from the beginning of training than to correct faulty ones later.
Due to the high level of knowledge and skill required in aviation for both pilots and maintenance technicians, training has traditionally followed a building block concept. This means new learning and habit patterns are based on a solid foundation of experience and/or old learning. Everything from intricate cognitive processes to simple motor skills depends on what the student already knows and how that knowledge can be applied in the present. As knowledge and skill increase, there is an expanding base upon which to build for the future.
How Understanding Affects Memory
The ability to remember is greatly affected by the level of understanding of what has been learned. Many studies have demonstrated a depth-of-processing effect on memory: the more deeply humans think about what they have learned, the more likely they are able to retrieve that knowledge later. Depth-of-processing is the natural result of the kinds of learning activities described earlier: beginning with memorized information and then elaborating upon it, making associations, constructing explanations, all in pursuit of furthering understanding.
The effects of depth of processing on memory are quite powerful and result from even the simplest attempts to elaborate on what has been learned. One study asked participants to memorize sentences such as “The pilot arrived late.” Half of the participants simply memorized the sentences as they were. The other participants were asked to develop an elaboration for the sentence such as “because of the bad weather.”
When put to a test, participants who created elaborations were signiﬁcantly better able to recall the sentences. When memories for sentences had decayed, it seems that remembered words from the elaborations helped people recall them.
Remembering During Training
Remembering what is learned on a day-to-day basis is the ﬁrst challenge students must meet. As students are presented with new knowledge each day, they must work to maintain that new knowledge plus all the knowledge they learned on previous days. Indeed, remembering during training is a challenge that increases in magnitude each day.
The ﬁrst threat to newly acquired knowledge is a lack of frequent usage in the past. To address this threat, the student must engage in regular practice of what they have learned. Students often put off daily studying in favor of “cramming” the night before an evaluation. These students should be made aware that shorter and regularly spaced study sessions produce memory results that far exceed those obtained from cramming.
A second threat to newly acquired knowledge is a lack of understanding that might serve to assist the student in recalling it. It has been demonstrated that study practices that combine repetition of knowledge along with efforts to increase one’s understanding of the knowledge lead to best results. The idea of reading with “study questions” in mind is one that has received much attention by memory researchers.
Experiments have found that not only does answering study questions lead to better memory, but so does the very act of creating study questions. In one experiment in which students read a text and were then tested on their comprehension, students who wrote their own study questions and then discarded them unanswered exhibited better recall than students who simply read the text.
Remembering After Training
Students must leave the training environment with a sound understanding that a certiﬁcate is in no sense a guarantee that they will remember anything that they have learned. It seems that no one is exempt from the process of forgetting. Continued practice of their knowledge and skill is the only means of retaining what they learned, and practice is important after they become certiﬁcated pilots and mechanics as it is during their training.
One study of pilots’ retention of aeronautical knowledge showed that students’ retention of some topics was superior to that of their own instructors. It seems that the students’ active use and recent rehearsal of these knowledge topics in preparation for knowledge and practical tests outweighed the effects of the more frequent (but less recent) usage on the part of the instructors. This ﬁnding nicely demonstrates that an instructor’s knowledge is just as vulnerable to forgetting when it has not been recently practiced.
In the same study, the ability of certificated pilots to remember details about regulations was related to the number of months since each pilot’s last ﬂight review. This suggests that pilots may take steps to sharpen their knowledge before a ﬂight review and allow it to decay between reviews. Even skills that become automatic during training may not remain automatic after a period of disuse.
Sources of Knowledge
Aviation students obtain knowledge from a variety of sources while training to be pilots or mechanics. The aviation instructor is the student’s primary source of knowledge, but an instructor also recommends other sources of knowledge. These include books, photographs, videos, diagrams and charts, and other instructional materials. These sources are important for the student because they allow information to be archived and easily transferred from one person to another. They also allow the reader to self-pace the acquisition of information and permit the reader to pause, think, formulate, and reformulate his or her understanding.
The instructor also encourages the student to gain experience in the real world of aviation. These experiences enhance the student’s incidental learning: observation of other pilots or mechanics, thinking about what has been learned, formulation of schemas, and ability to make correlations about what has been learned. Interactive computer-based instruction programs, another excellent source of knowledge, often go hand-in-hand with the ﬂight training syllabus, assuring academics are delivered just-in-time to complement lessons.
Summary of Instructor Actions
To help students remember what they have learned, the instructor should:
Discuss the difference between short-term memory and long-term memory.
Explain the effect of frequent and recent usage of knowledge on remembering and forgetting.
Explain the effect of depth of understanding on remembering and forgetting.
Encourage student use of mnemonic devices while studying.
Explain the beneﬁts of studying at regularly spaced intervals, and the disadvantages of “cramming.”
Learning theory has caused instruction to move from basic skills and pure facts to linking new information with prior knowledge, from relying on a single authority to recognizing multiple sources of knowledge, and from novice-like to expert-like problem-solving. While educational theories facilitate learning, no one learning theory is good for all learning situations and all learners. Instruction in aviation should utilize a combination of learning theories.
