In this sub-section, we will look briefly at early
work done by the Russian, Pavlov, who noticed interesting occurrences
when he was working on some studies with dogs. He noticed that he
could teach dogs to salivate (produce saliva) at the sound of a
bell. The way he did this was to sound a bell when a piece of meat
was presented. The dog would salivate at the sight and smell of
the meat. After a while, just the ringing of a bell would lead to
the dog salivating, even though there was no meat presented. The
dog had made an association between the sound of the bell and the
presenting of meat. The learning of associations
made in this way is called conditioning. This type
of learning is called classical conditioning because
the principles are based on the first studies in the field.
You might then say, how is this of value to me
in the classroom? Well, we all make associations between certain
stimuli (environmental occurrences) and these associations influence
our responses. For example, an educator decides that she will read
an exciting book to her class for the last ten minutes of each school
day. Her learners thus link her reading of the book aloud with the
pleasant experience of the end of the school day. Eventually just
taking out the book makes the class feel excited. Thus, even if
she takes out the book at another time during the day, they associate
the book with a pleasant event and it impacts on their feelings.
In contrast to this, many learners experience test anxiety. This
occurs after a learner has written a test in which he has done badly.
He then associates the feeling of not being adequate with the writing
of tests, and this might become generalized to other subjects, so
that every time he writes a test he feels shaky.
1.4.2 Operant conditioning
The second group of important theoretical principles
in behaviourism began with work by Skinner in the USA, prior to
World War II. Skinner noticed that both humans and animals are active
or operant in their environments. In other words
we do various things during each day. We are likely
to do something more often when we receive praise (a reinforcement)
for that action. For example, if you have worn some new clothing,
and a number of people have commented on how good you look in that
outfit, you are more likely to wear that clothing more often. Thus,
the reinforcement you received for that behaviour
increases the likelihood that you will repeat the behaviour. On
the other hand, when you were a learner, did you do something that
earned you verbal criticism or even a beating? For example, you
might have arrived at school late, and then been told be your teacher
that as a result you were to stay for half an hour after school
as punishment. This experience would then have
encouraged you to be on time for school to avoid punishment. In
this approach, we look at the behaviour which occurs and the consequences
of the behaviour. In operant conditioning therefore, our behaviour
is conditioned by its results – do we get reinforcement (for
example praise or a prize) or do we get punished in some way? Behaviour
for which there is positive reinforcement is then more likely to
be repeated, and that which is punished is likely not to be repeated.
1.4.3 Strategies for changing learner behaviour
Now that you have a better understanding of the
behavioural perspective of learning, we can examine how you can
develop strategies for changing learner behaviour.
One of the module writers notes:
On a school visit to observe a student
educator on teaching practice, I observed learners display quite
unruly behaviour and ignore the student educator’s attempts
at maintaining order in the classroom. During our discussion
after the lesson, the student educator drew my attention to
the problems she was experiencing with managing her class. She
believed her task was made more difficult because she was young
and inexperienced. Also the fact that she was a student educator
did not earn her the respect teachers in the school enjoyed.
Much of this was true, but she later discovered that even the
more experienced educators experienced difficulties with some
learners. In attempting to assist her, I refocused her attention
on some of the things she had learnt from the behavioural approach
to learning. We realized that she was not praising those learners
who were displaying cooperative behaviour, and that she had
not developed any rules with the class about the consequences
of unruly behaviour (in other words what the punishment would
be). Once she learnt about reinforcement and appropriate punishment,
things began to improve.
In research where educators' behaviour in classrooms
has been observed, it has been noted that many educators are quick
to punish but are slow to praise. However, where educators are more
positive, and look for behaviour to praise and encourage, there
is a much more creative and respectful climate in the classroom.
Learners are more keen to come to school, and they feel less anxious
and fearful. Where learners have a very negative attitude to school,
it may be due to many years of only receiving negative messages
about their performance and behaviour, with little positive reinforcement
of what they can do well.
How can we use reinforcement effectively?
There are a number of suggestions we can make,
to assist educators in managing learner behaviour more effectively.
Provide learners with a clear description
of desired behaviours: Think back to the Zinzi case study at
the beginning of 1.4. Mrs Ngubane reminded her learners what the
appropriate behaviour was when she asked a question in class. When
learners are behaving appropriately or in ways we desire, then we
should immediately reinforce such behaviour with the intention of
providing learners with a reason to behave in ways which we as educators
desire. As an educator, what would you consider to desirable behaviours
in a learner? When asked, educators often mention the following,
which are only some examples:
- Completing classroom tasks on time
- Working independently when required to do so
- Interacting in a sociable and agreeable manner
with others
- Completing and handing in assigned work on
the due date
Reinforcements are usually more effective when
they follow actual examples of such behaviours.
Stimuli and responses: When you walk
into a classroom as a new educator, the learners will respond to
you and what you have planned for them. They will respond to the
lesson you present, the test you administer, the rules you establish,
the questions you pose or the instructions you provide. A constant
concern is how they will respond. Will they respond to your instructions,
follow your rules, answer your questions or pay attention when you
demonstrate an experiment? Much of the answer depends on the clear
and consistent relationships which you establish with learners.
Choose an appropriate reinforcer: Different
reinforcers will be effective for different learners. You may find
that praising a learner’s good behaviour reinforces that behaviour
in one learner but not in another. The common approach is to observe
learners’ behaviour and be alert for consequences that learners
prefer and appreciate. The following are some examples of reinforcers
that are effective:
- Praise and encouragement
- A special privilege or a preferred activity
- Positive feedback on achieving success
Make response-consequence links explicit:
A reinforcement is more likely to be effective when learners know
what behaviours are expected of them and what consequences will
follow these behaviours. A learner is more likely to complete a
class task if he knows that he will be allowed some free time to
work on a favourite activity.
Administer reinforcement consistently:
Responses will increase if they are reinforced every time they occur.
We refer to this as continuous reinforcement. A
teacher is likely to see improvements in a learner’s behaviour
if he/she reinforces that desired response whenever it is observed.
Monitor learners’ progress: Behavioural
theorists advocate that educators attempt to determine, as objectively
as possible, the effectiveness of reinforcement on learners’
behaviour. It is also important to assess the frequency of a desired
behaviour before and during one’s attempts to increase it.
The frequency of the behaviour before we apply reinforcement is
referred to as the baseline level of that behaviour. We can determine
the effectiveness of reinforcement by comparing the baseline frequency
with the frequency of the behaviour after we begin to reinforce
it. If there are no significant changes then the reinforcer is ineffective
and needs to be changed
Alternatives to corporal punishment
Corporal punishment was abolished in our schools
a number of years ago, yet we are aware that there are still schools
who break the law by continuing to use it. Behavioural approaches
offer other alternatives to corporal punishment, because using corporal
punishment increases the cycle of violence in our society.
