Learning Theory
Learning theory may be described as 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, derived from theories,
can be useful to aviation instructors and developers of instructional programs
for both pilots and maintenance technicians.
Over the years, many theories have attempted to explain how people
learn. Even though psychologists and educators are not in complete agreement,
most do agree that learning may be explained by a combination of two basic
approaches: behaviorism and the cognitive theories.
Behaviorism
Behaviorists believe that animals, including humans, learn in
about the same way. Behaviorism stresses the importance of having a
particular form of behavior reinforced by someone, other than the student, to
shape or control what is learned. In aviation training, the instructor provides
the reinforcement. Frequent, positive reinforcement and rewards accelerate
learning. This theory provides the instructor with ways to manipulate students
with stimuli, induce the desired behavior or response, and reinforce the
behavior with appropriate rewards. In general, the behaviorist theory
emphasizes positive reinforcement rather than no reinforcement or punishment.
Other features of behaviorism are considerably more complex than this simple
explanation. Instructors who need more details should refer to psychology texts
for a better understanding of behaviorism. As an instructor, it is important to
keep in mind that behaviorism is still widely used today, because controlling
learning experiences helps direct students toward specific learning outcomes.
Punishment is defined as
anything which decreases the probability of a particular behaviour, either by
the production of something unpleasant or the removal of something rewarding
after the behaviour.

Examples suitable for
the classroom

|
Positive reinforcement
|
Increase
|
Praise, merit marks, sweets
for good contributions to class discussion.
|
Negative reinforcement
|
Increase
|
Removal of threat of detention
if a pupil produces past homework.

Punishment - produce
something unpleasant
|
Decrease
|
Keep a child back during
breaktime or give them a detention.
|
Punishment - remove
something pleasant
|
Decrease
|
Prevent child from joining in
a game at the end of the lesson.

A particularly effective way to
reduce the occurrence of a behaviour is to ensure that it is not reinforced;
this is known as extinction. Punishment is less effective because it only
suppresses behaviour temporarily; eventual removal of punishment allows the
behaviour to reappear. Skinner also added that punishment has unpleasant side-effects
such as group unhappiness.
- Secondary Reinforcers.
These would not normally be reinforcing in themselves, but are recognised
as steps on the way to obtaining the reinforcement. For a rat learning a
route through a maze, the recognition of a particular part of the maze is
reinforcing as it confirms that it is on its way to the food at the end.
In this way a chain of simple behaviours can be set up to produce
something more complex.
In other instances a secondary reinforcer can be paired with more than one primary reinforcer; it is then known as a generalised reinforcer. The obvious example is money, but it could be stars in school; ten stars could be traded for a primary reinforcer, perhaps a chocolate bar(footnote 3). Other secondary reinforcers that can be used in the classroom include verbal praise, points and grades. - Discriminative Stimuli. These antecedents signal when a particular behaviour will have a certain effect and when it won't. For example the discriminative stimulus might be the teacher; one can be baited another refuses to be.
- Reinforcement Schedules.
These describe the reinforcement regime; reinforcement is presented after
fixed or variable-
periods of time or number of behaviour instances.
In general using partial reinforcement ie not for each response was found to produce the most enduring learning.
