What
kind of questions do the behaviorists ask?
Why?
According
to B.F. Skinner, there are essential questions that a behaviorist must
ask in the study of organisms (1954, Harvard Educational Review, Vol.
24, No. 2). Three key concepts stand out among these questions. The
first question, what behavior is to be set up? is of importance
because there is a possibility that automatic reinforcement is present
without aversive properties when looking at the material to be learned.
What reinforcers are at hand? This is the next question asked. Behaviorists
believe that an organism needs reinforcements to keep them interested
and the use of such can be effective in controlling behavior. Taking
into account these reinforcements, how are these reinforcements to be
made contingent upon the desired behavior? Complex learning requires
a series of small steps and reinforcements for success at achieving
each step. In Skinners words, this is called complex repertoire
of behavior (pg. 4). Therefore, small steps equal the greater
instances of reinforcement and less aversive consequence.
Behaviorists View on Teaching
Skinner among other behaviorists note shortcomings of the 1950s
traditional classroom as the following:
(information from 1954, Harvard Educational Review, Vol. 24, No. 2)
To break these habits, a teacher needs to bring desired behavior under
many sorts of stimulus control. To achieve this, teaching should be
broken into progressive stages or steps with reinforcements following
each stage. The reality is that the contingencies required for desired
behavior in a class is far beyond what teachers/humans can realistically
arrange. With that being said, the behaviorists support the idea of
instrumental aid as a necessary means for effective control of human
learning. In the mid 20th century, the idea of new technologies in the
classroom were just being introduced. In 1954 a machine to teach arithmetic
was developed. The device was made to be used by children without constant
supervision of a teacher. It provided direct reinforcement by the ringing
of a bell for the desired response. A combination spelling and math
machine was later developed where new problems were only presented if
a child (user) answered a question correctly. It is of interest that
presently in the 21st century, technology has taken huge leaps in instruction
design. The same arguments arise from the 1950s to the present
that a teachers relation cannot be duplicated by a mechanical
device and mechanized instruction will mean technological unemployment
(pg. 6). In response to such objection the behaviorist note that
instrumental help improves teacher-student relations. Such technologies
frees up time for teachers that will enable to focus more on the student.
Behaviorists View on Learning and the Learner
In the early 1900s behaviorist (although the term was not employed
at the time) John Watson launched the behaviorist revolution. Moving
from mainstream thought that the proper subject for psychology
was not the operation of the mind but rather the examination of objective,
observable behavior. (Gardner, H. 1985, The Minds New Science).
According to him, humans and animals can be trained to do anything one
wanted. This set the stage for others to investigate the idea of cognitive
maps in guiding the behavior of animals in problem solving. By the arrangement
of reinforcement, an learners behavior can be shaped. By progressively
changing contingencies of reinforcement, the desired behavior will surface.
In other words, the behavior of a learner can be controlled by manipulation
of reinforcements. Furthermore, in order to maintain behavior, reinforcements
need to continue pr maintaining it in strength. Skinner (1954, Harvard
Educational Review, Vol. 24, No. 2) believed that students have been
taught to learn through aversive stimulation. To summarize, the main
principles that he and current behaviorists believe for learners is
the following:
1. Behavior that is positively reinforced will reoccur; intermittent
reinforcement is particularly effective.
2. Information should be presented in small amounts so that responses
can be reinforced (shaping).
3. Reinforcement will generalize across similar stimuli (stimulus
generalization) producing secondary conditioning.
