LEARNING
Definition
Introduction
This unit gives the definition of learning and identifies and discusses the elements
necessary for effective learning processes. Phases of learning and factors necessary for
learning are also explored.
Specific Objectives
1. Define terminologies used in human learning and memory learning and explain the
key concepts in the definition.
2. Change in behaviour
3. Repeated experiences
Note
The use of the term ‘permanent’ excludes behaviour that is temporary e.g. drunkenness
and behaviour due to illness, injury, fatigue.
The term’ behaviour ‘implies that learning is not directly observable, but manifests itself
in ones’ repeated actions.
Practice ‘is used in the definition to exclude change in behaviour that is due to
maturation, disease or physical change, fatigue, old age, etc.
i) The learner
A person who has a certain capacity for learning, needs and/ or problems that may
facilitate or hinder learning.
A stimulus is an object or event in the learner’s environment that may stimulate or affect
his/her sense organs, which transmit nerve impulses to the central nervous system where
they are interpreted or translated into response (action).
iii) Response
This refers to the nervous, mental or muscular activity/performance of the learner that
results front stimulation or manipulation. A lot of this performance may not be easily
observable for it is in overt, however some of it becomes visible (overt) and is described
as performance and is usually accounted for in terms of the learners’ observable changes
in behaviour.
Written Exercise 7
Phases of Learning
Learning takes place in five hierarchical sequences or stages because the interaction with
the stimuli at each stage is different from the other. Interference with learning at a
preceding phase, may affect learning at the next stage. E.g. if the learner is not active at
the first stage of attention, because he/she is looking out at the passers’ by, when the
teacher is explaining how to solve a simultaneous equation, the other phases i.e.
perception, acquisition, retention and transfer (generalization) will also be affected.
i) Attention
Attention refers to the learners’ field of vision or listening onto which focuses all his
mental faculties of observation at the exclusion of others. Learning begins with attention.
A boy who is watching basketball through the window, his attention is out in the field at
the expense of what is happening in the classroom. He will therefore find he does not
know the meaning of the formula a 2 = b2 + c which the teacher explained while he was
watching basketball. The same will happen to a girl who concentrates on examining
other girls’ hairstyles, make-up and clothes.
ii) Perception
This is the stage at which the input from the sense (eyes, ears, tongue, nose and skin) are
registered and decoded or meaning added to it. Perception involves a bit of evaluation
and synthesis of new with the old information. Perception is usually dictated by:
1. Subject being learned, e.g. flower in Biology will not be registered in the same way
as in a fine art class.
2. Learner’s previous experience: for a child who has been stung by a bee the word bee
represents a frightening ordeal while it may simply be an enjoyable spelling game for
another child.
NB: In planning teaching material, the teacher should always put himself/herself in the
learner’s shoes/position so as to be able to more effectively manage the learner’s
perceptions. Ask yourself: How will the learners see this? Is it attractive? What picture
will it portray? Can the learner make appropriate discrimination? Is the right language
used?
iii) Acquisition
This is the phase at which the learner has attained a new skill, knowledge, ability or
disposition that he/she did not have before. It is characterized by new ability or insight to
see or do things he/she could not do earlier.
iv) Retention
This is the learners’ ability to keep in store for some time or retain what he/she has
learned. It is the learner’s ability to recall or reproduce what he/she has learned for future
use. Effective retention is determined by previous learning experiences, organization
methods, distribution of learning experiences and the amount/quality of practice given
during and after learning.
v) Transfer (Generalization)
This is the learner’s ability to carry over skills, knowledge, performance gained in one
topic, course, and level of life to another area, course, topic or operation. It is also
evident when learning in one area facilitates (or hinders) mastery of skill or knowledge
in another or different situation.
Transfer is the aim of all learning for it enables the learner to use his/her school
knowledge and skills in totally different situations of life to solve basic problems of life.
Transfer depends very much on retention, but it is higher for it demands, - analysis,
discrimination, synthesis and application of skill and knowledge in novel situations.
retention merely refers to calls for the later reproduction of learned materials in the same
manner in which it was originally learned. In transfer, there is creativity and originality
as the initial material may be altered to suit certain individual or local needs.
Gagne (1970) distinguishes between two types of transfer:
. 1. Lateral and
2. Vertical
1. Lateral - This is observed when the learner is better able to perform other
somewhat related/similar but novel/new tasks of the same level of complexity.
E.g. if a student learned pregame, he/she then learns without further instruction to
give the meaning of preview, preschool, preset, preamble.
2. Vertical transfer - This occurs when the products of earlier learning are used or
become pre-requisites for later advanced or complex learning. Short
division/multiplication leads to long division and multiplication respectively. A lot
of learning proceeds in hierarchies of concepts principles, and skills, always
beginning with the simplest.
There must be something in common between the two activities such as facts,
skills, methods or principles.
The learner must be able to perceive the similarities between the two subjects
or activities.
The learner must have a high ability to gain insight into the principle
underlying the subject he/she is learning.
The learners’ reactions to later situations are influenced by their previous ex-
perience.
Make sure that learners have thoroughly mastered the subject content area before
moving to the next.
Help learners develop the right mental set, i.e. looking for the connections be-
tween one subject topic with the others.
Help learners gain insight into the rules underlying the subject they are learning.
Project method should be used in teaching so that learners can see for themselves
the connections between different subjects.
Activity 1
From information processing perspective there are three main stages in the formation and
retrieval of memory:
Retrieval - Calling back the stored information in response to some cue for use in a
process or activity.
There are generally three types of memory: sensory memory, short term memory and
long-term memory as can be seen on the diagram below.
Multi-store Model
Rehearsal
What is the importance of the memory stores in information processing?
Sensory memory
This is a very short-lived memory that takes place when environmental stimuli-impinge
on the sensory organs. The ability to look at an item and remember what it looked like
within just, a second of observation or memorization is an example of sensory memory.
This memory degrades extremely quickly and hence not dependable.
The sensory memories act as buffers for stimuli received through the senses. A sensory
memory exists for each sensory channel: iconic memory for visual stimuli, echoic
memory for aural stimuli and haptic memory for touch.
This memory allows recall for a period of several seconds to a minute without deliberate
rehearsal. Its capacity is also very limited without rehearsal. Short-term memory is
believed to rely mostly on an acoustic code for storing information and to a lesser degree
a visual code.
The storage in sensory memory and short term memory generally has a strictly limited
capacity and duration, which means that the information is available for certain duration
of time, but is not retained indefinitely. By contrast, long term memory can store much
large quantities of information for potentially unlimited duration (sometimes a whole life
span). The capacity can also approach infinity (unlimited). While short term memory
encodes information acoustically, long term memory encodes memory semantically
under what Jean Piaget referred to as mental schema.
What is the relationship between memory and learning?
Sensory memory
Sensory memory corresponds approximately to the initial 200 - 500 milliseconds after an
item is perceived. The ability to look at an item, and remember what it looked like with
just a second of observation, or memorization, is an example of j sensory memory. With
very short presentations, participants often report that they | seem to “see” more than
they can actually report. The first experiments exploring this form of sensory memory
were conducted by Sperling (1960) using the “partial report paradigm.” Subjects were
presented with a grid of 12 letters, arranged into three rows of 4. After a brief
presentation, subjects were then played either a high, medium or low tone, cuing them
which of the rows to report. Based on these partial report experiments, Sperling was able
to show that the capacity of sensory memory was approximately 12 items, but that it
degraded very quickly (within a few hundred milliseconds). Because this form of
memory degrades so quickly, participants would see the display, but be unable to report
all of the items (12 in the “whole report” procedure) before they decayed. This type of
memory cannot be prolonged via rehearsal.
Short term memory allows recall for a period of several seconds to a minute without
rehearsal. Its capacity is also very limited: Miller (1956), when working at Bell
Laboratories, conducted experiments showing that the store of short-term memory was
7±2 items (the title of his famous paper, “The magical number 7±2”). Modern estimates
of the capacity of short-term memory are lower, typically on the order of 4-5 items, and
we know that memory capacity can be increased through a process called chunking. For
example, if presented with the string:
FBIPHDT WAIBM
People are able to remember only a few items. However, if the same information is
presented in the following way:
people can remember a great deal more letters. This is because they are able to chunk the
information into meaningful groups of letters. Beyond finding meaning in the
abbreviations above, Herbert Simon showed that the ideal size for chunking letters and
numbers, meaningful or not, was three. This may be reflected in some countries in the
tendency to remember phone numbers as several chunks of three numbers with the final
four-number groups generally broken down into two groups of two.
Short term memory is believed to rely mostly on an acoustic code for storing infor-
mation, and to a lesser extent a visual code. Conrad (1964) found that test subjects had
more difficulty recalling collections of words that were acoustically similar (e.g. dog,
hog, fog, bog, log) however, some individuals have been reported to be able to rein
ember large amounts of information, quickly, and be able to recall that information in
seconds.
The storage in sensory memory and short-term memory generally has a strictly limited
capacity and duration, which means that information is available for a certain period of
time, but is not retained indefinitely. By contrast, long-term memory can store much
larger quantities of information for potentially unlimited duration (sometimes a whole
life span). The capacity can also approach infinity (unlimited). For example, given a
random seven-digit number, we may remember it for only a few seconds before
forgetting, suggesting it was stored in our short-term memory. On the other hand, we can
remember telephone numbers for many years through repetition; this information is said
to be stored in long term memory. While short term memory encodes information
acoustically, long term memory encodes it semantically: Baddeley (1966) discovered that
after 20 minutes, test subjects had the least difficulty recalling a collection of words that
had similar meanings (e.g. big, large, great, huge).
There are two types of long-term memory: Declarative and Procedural. Declarative
memory deals with facts and is further divided into episodic and semantic memory.
Episodic memory represents our memory of events and experiences in a serial form. It is
from this memory that we can reconstruct the actual events that took place at a given
point in our lives. Semantic memory, on the other end, is a structured record of facts,
concepts and skills that we have acquired. The information in semantic memory is
derived from that in our own episodic memory, such that we can learn new facts or
concepts from our experiences. Procedural memory deals mainly with psychomotor
skills such as riding a bicycle or playing a guitar.
There are three main activities related to long term memory: storage, deletion and
retrieval.
Information from short term memory is stored in long term memory by rehearsal. The
repeated exposure to a stimulus or the rehearsal of a piece of information transfers it into
long term memory. Experiments also suggest that learning time is most effective if it is
distributed over time. Deletion is mainly caused by decay and interference. Emotional
factors also affect long term memory. However, it is debatable whether we actually ever
forget anything or whether it becomes increasingly difficult to access certain items from
memory. Having forgotten something may just be caused by not being able to retrieve it!
Information may not be recalled sometimes but may be recognized, or may be recalled
only with prompting. This leads us to the third process of memory: information retrieval.
There are two types of information retrieval: recall and recognition. In recall, the
information is reproduced from memory. In recognition the presentation of the in-
formation provides the knowledge that the information has been seen before. Rec-
ognition is of lesser complexity, as the information is provided as a cue. However, the
recall can be assisted by the provision of retrieval cues, which enable the subject to
quickly access the information in memory.
Written Exercise 8
2. Discuss the three main memory storage showing how each one of
them affects learning. (12 marks)
Disorders of memory
Much of the current knowledge of memory has come from studying memory disorders.
Loss of memory is known as amnesia. There are many sorts of amnesia, and by studying
their different forms, it has become possible to observe apparent defects in individual
sub-systems of the brain’s memory systems, and thus hypothesize their function in the
normally working brain. Other neurological disorders such as Alzheimer’s disease can
also affect memory and cognition. Hyperthymesia is a disorder which affects an
individual’s autobiographical memory, essentially meaning that they cannot forget small
details that otherwise would not be stored. Korsakoff s psychosis, is an organic brain
disease that adversely affects memory.
Memorization
At the Center for Cognitive Science at Ohio State University, researchers have found that
memory accuracy of adults is hurt by the fact that they know more than children and tend
to apply this knowledge when learning new information. The findings appeared in the
August 2004 edition of the journal Psychological Science.
Emotion can have a powerful impact on memory. Numerous studies have shown that
the most vivid autobiographical memories tend to be of emotional events, which are
likely to be recalled more often and with more clarity and detail than neutral events.
What are some of the disorders of memory and how can they be prevented?
Improving memory
It is inconclusive that memory may be improved via simple lifestyle changes such as
undertaking memory exercises, eating healthily, engaging in moderate physical activity,
and reducing stress.
The International Longevity Center released in 2001 a report which includes in pages 14-
16 recommendations for keeping the mind in good functionality until advanced age.
Some of the recommendations are to stay intellectually active through learning, training
or reading, to keep physically active to promote blood circulation to the brain, to
socialize, to reduce stress, to keep sleep time regular, to avoid depression or emotional
instability and to observe good nutrition.
Memory tasks
• Paired associate learning - when one learns to associate one specific word with
another. For example when given a word such as “safe” one must learn to say
another specific word, such as “green”. This is stimulus and response.
• Free recall - during this task a subject would be asked to study a list of words
and then sometime later they will be asked to recall or write down as many words
that they can remember.
Levels of processing
Craik and Lockhart (1972) proposed that it is the method and depth of processing that
affects how an experience is stored in memory, rather than rehearsal.
Organization - Mandler (1967) gave participants a pack of word cards and asked them to
sort them into any number of piles using any system of categorization they liked. When
they were later asked to recall as many of the words as they could, those who used more
categories remembered more words. This study suggested that the act of organizing
information makes it more memorable.
Effort - Tyler et al. (1979) had participants solve a series of anagrams, some easy
(FAHTER) and some difficult (HREFAT). The participants recalled the difficult
anagrams better, presumably because they put more effort into them.
Think of your brain as one of the most powerful muscles in your body, because in a
sense it is. It may be an organ however, without it, where would one be? People spend a
lot of money yearly to workout in gyms, go to spas for relaxing massages, and do
everything in their power to stay physically appearing young, however they fail to take
the same care and consideration to the most powerful part of their body, their brain.
Without exercising your brain, you will lose its powerful functioning that was the reason
behind your success to maintain the job that enabled you to hit the gyms, spas, and other
forms of treatments to stay looking young. That is your first tip in improving your
memory, work the brain, or lose it.
You can exercise your brain by stimulating it to new information, hobbies, and
knowledge. Other ways you can exercise your brain is by moving away from mindless
television and picking up a book, playing board games, memory games, doing crossword
puzzles and other types of puzzles that force you to think. Break away from normal
routines that become monotonous. How many times have you felt your car could drive
you home from work because you have never strayed from a beaten path? It is the same
way with your brain; if you do not give it new surroundings from time to time, it
becomes stale or stagnant. Do anything you can do to throw a little spice up into your
brain’s life.
That is just one tip that will help improve your memory, recall ability, and knowledge
base. Here are some other essential tips to help one improve their memory.
Pay close attention to details in print or when someone is speaking to you. Many
times we assume we know where the conversation is leading so we tone out parts,
if not the majority of it. Learn to focus closer on conversations and details even if
you do not think they are pertinent. It takes eight seconds for your brain to
process a piece of information. Practicing focusing even with the most boring
conversation will help you drastically in improve your memory and recall skills.
Know your learning style and try to take in new information in that style. It will
help your brain process the information quicker and even help cut down on study
time.
Use as many styles of learning that are best suited for you. Try to utilize as many
senses in your learning styles as possible. The more styles utilized the more your
brain will absorb as well as you are giving your brain an excellent workout.
When taking in new complex material, learn to repeat it back aloud in your own
words then write the information in your own words.
Remember the days of spelling words and writing them repeatedly to memorize
them. It worked then and it will work still at the age of 30, 40 and 50 and up.
Remind yourself frequently that you want to improve your memory. This alone
will help improve your memory up to 30% if done actively.
Forgetting
Forgetting (retention loss) refers to apparent loss of information already encoded and
stored in an individual’s long-term memory. It is a spontaneous or gradual process in
which old memories are unable to be recalled from memory storage. It is subject to
delicately balanced optimization that ensures that relevant memories are recalled.
Forgetting can be reduced by repetition and/or more elaborate cognitive processing of
information. Reviewing information in ways that involve active retrieval seems to slow
the rate of forgetting.
Forgetting functions (amount remembered as a function of time since an event was first
experienced) have been extensively analyzed. The most recent evidence suggests that a
power function provides the closest mathematical fit to the forgetting function.
History
Theories of forgetting
The four main theories of forgetting apparent in the study of psychology are as follows:
1. Cue-dependent forgetting
2. Trace decay
Trace decay focuses on the problem of availability caused when memories decay. Hebb
said that incoming information creates a pattern of neurons to create a neurological
memory trace in the brain which would fade with time. Repeated firing causes a
structural change in the synapses. Rehearsal of repeated firing maintains the memory in
STM until a structural change is made.
3. Organic causes
Forgetting that occurs through physiological damage or dilapidation to the brain are
referred to as organic causes of forgetting. These theories encompass the loss of
information already retained in long term memory or the inability to encode new
information again. Examples include Alzheimer’s, Amnesia, Dementia, consolidation
theory and the gradual slowing down of the central nervous system due to aging.
4. Interference theories
Interference theory refers to the idea that forgetting occurs because the recall of certain
items interferes with the’ recall of other items. In nature, the interfering items are said to
originate from an over stimulating environment. Interference theory exists in two
branches, Retroactive and Proactive inhibition each referring in contrast to the other.
Retroactive interference is when new information (memories) interferes with older
information. On the other hand, proactive interference is when old information interferes
with the retrieval of new information.
5. Decay theory
Decay theory states that when something new is learned, a neurochemical, physical
“memory trace” is formed in the brain and over time this trace tends to disintegrate,
unless it is occasionally used.
Forgetting can have very different causes than simply removal of stored content.
Forgetting can mean access problems, availability problems, or can have other reasons
such as amnesia by an accident.
A debatable yet popular concept is “trace decay”, which can occur in both short- and
long-term memory. This theory, applicable mostly to short term memory, is supposedly
contradicted by the fact that one is able to ride a bike even after not having done so of the
decades. “Flashbulb memories” are another piece of seemingly contradicting evidence.
It is believed that certain memories “trace decay” while others don’t Sleep is believed to
play a key role in halting trace decay although the exact mechanism of this is unknown.
Causes of forgetting
Poor encoding
Use of drugs
Activity 2
2. Previous experiences
3. Maturation – certain behaviour and abilities are attained at a particular age e.g.
speaking, walking
7. Social and physical environment of the learners’ factors in the family e.g.
poverty, dysfunctional families, nutrition, learning environment in school.
Introduction
This unit deals with selected theories and approaches to learning. It defines the term
theory and explains its importance to teachers. Behaviourist and cognitivist theories and
approaches to human learning are also discussed. Conditioning and social learning are
explained.
Specific Objectives
A theory of learning is an attempt to explain and simplify the occurrence of events within
the learner’s environment and how such events influence his/her reaction to them. It is a
systematic interpretation of the observation made on the process of learning which tries
to explain the how and why of learning.
1. It makes clear to him/her the conditions, which are necessary for the prediction and
control of the learning process and for the successful achievement of set educational
objectives.
3. It makes the teacher’s decision and actions sounder as they are based on proven
evidences rather than relying totally on his/her own whims. This contributes to the
teacher’s professional growth and also helps him/her in the choice and evaluation of
professional literature and the whole curriculum in general.
The following major theories will be discussed to elucidate on the process of learning:
Behaviorist learning theories
Behaviourist Theories
Because no learning is required to make dogs salivate when they are given
meat powder, meat powder is referred to as an unconditioned stimulus (US)
and the reflex response of salivating is referred to as an unconditioned
response (UR).
Pavlov took the stimulus that did not cause salivation in dogs (bell) and
began to pair it systematically with the presentation of food. He would ring the bell,
immediately present the food (US) and observe the dog’s salivation (UR). After bell and
the meat powder had been paired or continuously associated, Pavlov was able to cause
salivation without giving the meat powder; ringing the bell was enough to elicit
salivation. The dog associated meat powder with the bell and would salivate.
The ringing bell had become a stimulus to which the dog responded in a predictable way.
For this reason, the bell is referred to as a conditioned stimulus (CS) and the response it
elicits is called a conditioned response (CR). See illustrations below.
Before conditioning
During conditioning
Neutral stimulus (bell) is paired with the unconditioned stimulus (meat powder), i.e. the
bell is rung followed closely by the presentation of meat powder. This elicits
unconditioned response (salivation). This process is repeated several times to condition
the dog to the ringing of the bell.
After conditioning
However, when "extinction has taken place (learning is at the zero level) the conditioned
stimulus could still elicit the conditioned response. This is referred to as spontaneous
recovery.
Reinforcement
Reinforcement is any procedure that strengthens learning and makes the recurrence of a
response more probable.
If a teacher wants learners to learn a concept well, then the teacher should reinforce
positive efforts made by the learners towards learning the particular concept. This could
be done by:
Using encouraging remarks such as: good, very good, excellent, correct, pre-
cisely, yes, good trial, etc.
Drawing other learners’ attention to a correct answer given by the one of the
learners.
Behaviour
(Learning)
Extinction point
Motivation
In the Pavlovian experiment, the dog was kept hungry for some time. Therefore, the dog
had the hunger drive which highly motivated its behaviours and responses. For effective
learning to take place, the learners must be driven by the desire to learn and be
interested, in the content. Objectives of the learning process and the expected outcomes
should be stated at the onset. The learning environment should be devoid of distracters.
Stimulus generalization
It is the process by which, once a stimulus has come to elicit a response, similar stimuli
may also elicit the response. The more alike the new stimuli are to the original, the more
likely they are to produce/evoke the conditioned response. E.g. a dog that learns to
salivate to the sound of a bell of a given sound or pitch associated with food will also
salivate to higher/or lower sounds or tunes without further conditioning. In school, you
teach the principles of simple equations in algebra. The teacher’s expectation in giving
more complex algebra is for them to generalize. Learning of grammar or mathematical
formulas best lend themselves to the concept of stimulus generalisation. For example:
1. Singular Plural
Desk Desks
Cat Cats
Dog Dogs
There is the generalisation that plurality of words is derived by adding an ‘s’ at the
end of the word.
2. If the formula for the area of a triangle is half base times height, the formula can be
applied in the finding of areas of other triangles and even in deriving bases and
heights of triangles given the area.
3. The teacher creating good teacher-learner relationship, which will make the learners
like the teacher as a person and eventually like the subject, can make , stimulus
generalisation in the learning situation.
Stimulus discrimination
In the Pavlovian experiment, when the bell sound (CS) is numerously not
followed with the meat powder (UC), the dog‘s salivation (CR) gradually
wanes and finally disappears. This is called extinction. It clearly explains why learners
forget a concept they have been taught especially when the teacher makes no effort to
encourage (reinforce) the learners’ efforts.
However, when Pavlov, after some period of time rang the bell, the dog whose sali vation
had suffered extinction, salivated. This is referred to as spontaneous recovery. This
means that the dog had not completely forgotten the previous association between the
bell and the meat powder. The concept of spontaneous recovery explains the principles
underlying the processes of remembering/ recall of a forgotten concept by learners.
Skinner developed the operant conditioning theory by designing a box having the
following features:
A hungry rat.
Food pellets attached to the lever mechanism but out of reach to the rat.
A food tray on which food pellets could drop when the lever is pressed.
The box had no exit point for the rat but was well ventilated.
Naturally, the rat started wandering around in the box in search of food or exit because it
was hungry. The rat moved from one comer of the box to another but it found neither
food nor exit. Accidentally, the rat pressed the lever bar and food pellets dropped on the
food tray placed on the floor of the cage box and the rat had food to eat. Further
wandering around did not lead to food dropping on the food tray. Food only dropped
when the rat pressed on the lever bar.
The rat started concentrating/focusing all its efforts on pressing the lever bar, which led
to the food pellets dropping. The rat had thus learned that it is only when pressing the
lever bar that food drops for its consumption. It stopped wandering carelessly. The rat
had learned to discriminate between its responses, which led to reinforcement/ reward,
and those, which did not.
What is the difference between reinforcement and punishment?
Skinner’s experiment involved a rat, which had been kept hungry for some time. The rat
was thus motivated by the hunger drive to move around in search of food. The rat would
not have moved around if it were satisfied. It therefore would not have learned about
pressing of the lever bar, which resulted to food droplets.
For the learning process to be effective, the learners involved must be highly motivated
to learn. This could be achieved by:
Making the learners aware of the lesson objective! at the beginning so that they
focus towards the objectives.
Make the learners expectant of positive outcomes of the learning process. No one
would put efforts in learning tasks whose outcomes are not useful.
During assessment, the teacher should formulate questions in such a way that the
correct response is likely to occur.
Stimulus discrimination
The rat in the Skinnerian experiment learned that it was only by pressing the lever bar
that food pellets dropped on the food tray. The rat thus learned to concentrate on the
lever and minimized other fruitless movements within the box.
Meaningful learning takes place only when learners focus their efforts to those responses
leading to outcomes in tandem with the set objectives. Teachers should ensure that the
content is clear and in consonant with the objectives. Questions and exams given to the
students should test the achievement of the set objectives.
Shaping behaviour
Skinner found out that even if the rat could not be able to learn to press the bar on its
own in order to get the food droplets, it (rat) could gradually be made to learn by
breaking the task into smaller but achievable tasks.
The teacher should, therefore, analyze thoroughly the subject matter*and subdivide the
content into meaningful segments of information. This information should then be
presented to the learners in an ascending order from the simple to the complex.
Operant extinction
Activity 1
1. Visit a local primary and secondary school find out and compare the
methods used by teachers to motivate students to learn.
Both involve some kind of learning and association i.e. two things are related
together.
In both such concepts as stimulus generalization and discrimination
are similar.
Most of these factors exist for biological reasons. The biological purpose of the Principle
of Satiation is to maintain the organism’s homeostasis. When an organism has been
deprived of sugar, for example, the effectiveness of the taste of sugar as a reinforcer is
high. However, as the organism reaches or exceeds their optimum blood-sugar levels, the
taste of sugar becomes less effective, perhaps even aversive.
This theory states that people learn through observation of others’ behaviours. Simply
put:
Bandura asked nursery-school children to observe an adult model striking a large inflated
Bobo doll with a mallet. The model also hit, kicked and sat on the doll. During the
assault, the model said a number of unusual sentences unlike any of the children had
heard before. Neither the model nor the observing children was directly involved at any
time during the session.
Later after the model had gone, the children were secretly observed as they played in a
toy-filled room with the Bobo doll. For comparison, other children who had not seen the
model’s behaviour were also allowed to interact with the doll.
The results of the experiment clearly demonstrated that the children who had observed
the model were far more likely to be aggressive in imitation of the model’s behaviour
than other children who did not observe the model. Another experiment performed by
Bandura indicated that social learning could be reinforced.
Behaviour patterns are learned in context. For instance, an adult, (male or female)
reacts one way with men and another with women
Behaviour can be modified via symbols. Social learning theory places special
emphasis on the symbolic environment. Most of our actions are based on our
images of reality, which are largely derived from symbolic media.
Written Exercise 9
Concepts of cognitive psychology as discussed below draw a lot from the contributions
of Jerome Bruner, David Ausubel and Robert Gagne.
Discovery learning
Instead of revealing to the pupils the major concepts and principles they are ex-
pected to learn from a lesson, a teacher should give pupils the opportunity of
discovering them for themselves.
Discovery learning calls for active participation on the part of the pupils. It is a
beneficial approach because pupils are able to retain information longer.
Intuitive thinking
• Bruner also advocates the importance of intuitive thinking to the education of the
children.
• That scientific reasoning which starts with speculation is similar to intuitive thinking.
• Bruner emphasises that the teacher must match the curriculum to the pupils needs
rather than vice-versa. Pupils’ readiness for a curriculum is essential.
• It increases the learner’s interest in the task in which he/she is involved in.
Theory of instruction
The child must be predisposed to learn for any effective learning to take
place.
Teachers should foster the child’s intellectual growth and should exploit the
child’s curiosity and strong desire to explore and learn.
Structure
• What is taught should be in keeping with the learner’s cognitive structure and
understanding. .
• As far as possible, new material should have a bearing on what the learner already
knows.
Sequence
• If the content of a given subject is arranged sequentially, it will be easier for the
learner to comprehend what is being taught.
Relatively difficult subjects requiring more concentration and a high level of arousal
should be scheduled during the early hours of the day.
Reinforcement
The use of reinforcement encourages and sustains desirable and academic and social;
behaviour. This includes feedback, smiles, compliments and high marks.
Ausubel refers to this theory as verbal learning because most of what is learned in
the classroom is based on the use of language as a means of communication.
Learning is called meaningful because what is being learned is based on what the
students already know.
By assumption, it is meant that new materials are incorporated into the existing
information structure of the learner. This theory is summed up as follows:
‘That learning which occurs as a result of whatever a student learns being in
some way related to what he already knows,’ Ausubel (1978).
For meaningful learning to occur, the learners attention can be drawn to the
related information and relating it to new information.
Teachers would therefore have to begin with the most broad and general concepts
before proceeding to specific and differentiated topics. The advantages of
pursuing this approach are the following:
Assessing readiness- all that can be known about pupils with regard to their age,
level of capability, previous performance should be investigated to establish the
entrance behaviour.
Selecting material - when preparing a lesson on what he/she knows about the
class, the teacher should concentrate on major points and outlines them as clearly
as possible.
Stressing principles and concepts - it is important that the teacher stresses prin-
ciples and concepts, otherwise pupils will be tempted to resort to rote learning.
Robert Gagne (1985) is responsible for developing this theory which has the fob lowing-
features:
Types of learning
Gagne identified five forms of learning, which may be influenced by conditions existing
within the learner or outside his/her environment or both. The different types of learning
are arranged in a hierarchical order so that lower types have to be acquired before .the
higher ones can be.
• Signal learning - This is automatic learning and may be based on reflex actions e.g.
eye blink.
• S-R learning - This may be a voluntary or specific skills response e.g. a smile being
reciprocated with a smile, a red traffic signal causing one to stop one’s vehicle.
• Simple chaining - This learning may involve motor skills such as touching, a stick
holds it and then tick, learning how to use it.
• Verbal association - This involves linking one word with another e.g. hot- cold, son-
father, or simply naming, memorising passages or acquiring vocabulary.
• Learning discrimination - This means learning how to discriminate or distinguish
one object from another even though they could be similar in nature.
• Concept learning - This involves learning how to sort objects on the basis of their
similarity or commonality and distinguishing between part and whole.
• Rule learning - This entails using different concepts to arrive at a conclusion and
being able to make a hypothesis regarding certain problems. E.g. when an object is
thrown up it will fall down, when a seed is planted, it will germinate.
• Problem-solving - This calls for the use of one’s acquired knowledge of rules. The
rules can be used for solving many problems.
Outcomes of learning
According to Gagne, there are five learning outcomes or objectives the acquisition of
which places a learner in a position of strength. The major objectives of learning are:
Verbal information.
Intellectual skills.
Cognitive strategies
Attitudes.
Motor skills.
Processes of learning
A person is exposed to a given stimulus, which triggers the sensory receptors. The
receptors store the information briefly then passes it to the short term memory and finally
to the long term memory for future retrieval.
These may be internal or external. Internal conditions involve the learner’s personality as
well as past experiences and personal cues for processing of new information. External
conditions include other factors that motivate the learner to remember earlier
information.
Educational implications
• Lessons should be prepared such that pupils are only introduced to concepts they are
able to comprehend at a particular stage.
• Verbal learning can be encouraged through reading, teaching, observation and group
discussion.
Written Exercise 10
Gestalt theory was developed by Max Wertheimer, Wolfgang Kohler and Kurt Kofka.
They argue that before an organism arrives at an insight regarding a particular problem;
it cognitively formulates a number of hypotheses as to how the problem may be solved
before acting.
Gestalt laws
1. The law of proximity - according to this law parts that are close in time or in a
space or both tend to be perceived together. E.g. the circles below are seen as
being three rows rather than columns.
00000
00000
2. The law of similarity - This law states that similar parts are seen together as
forming a group e.g. in the figure below, the symbols @ and # appear to belong
together and for this reason, they are perceived as columns instead of rows.
@#@#@#@#
@#@#@#@#
@#@#@#@#
…………………………………
…………………………………
…………………………………
3. The law of continuity - This law states that figures and drawings will be completed in
the same manner in which they are presented. In the figure below, the brackets, dots
and letter ‘o’ tend to be seen as a shape and not as separate unrelated entities.

Educational implications
Pupils should be encouraged to learn through insight and not through mechanical
drill and rote learning.
The behavior of a person is determined by his/her life space, which is a com-
posite of many interacting variables.
