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
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

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

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. Readiness
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
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.
