MODERN INSTRUCTIONAL STRATEGIES - AN OVERVIEW
2.1 INTRODUCTION
Effective learning for tomorrow demands instructional strategies
that can accommodate the variety of contexts in which teachers will teach, the
variety of content that must be learnt and the variety of learners with d~fferent
backgrounds, needs and problems. We use strategies of instruction to
provide reliable effective instruction to each learner through the application of
scientific principles of human learning. Many of today's strategies of
instruction have roots in theories that are hundreds or even thousands of
years old. But the body of theory that influences most strongly, the
development of today's instructional strategies is of much more recent origin.
An overview of the modern instructional strategies is given below.
2.2 PSYCHOLOGICAL BASES OF INSTRUCTIONAL STRATEGIES
To explain what strategies of instruction are, why they are used
and how they are used, we have to take a closer look at the following
~nstructional perspectives:
1 behavioural
2 cognit~ve
3. social psychological.
2 1 Theoretical Overview
The Behavioural Perspective
The most prominent behaviourist theorist is Skinner (1954) who
assumed that intellectual growth involves the formation of associations
between stimuli and responses as a result of reinforcement.
The boy sees, hears and feels the dog, he responds by smiling
and patt~ng the dog. The behaviourist view is that children learn language,
social behaviour and their understanding of the physical world is through the
rapid, continuous and often unconscious accumulation of associations, which
are strengthened or weakened throughout the child's waking hours (Skinner,
1954).
Skinner particularly focused on the importance of the
consequences of responses, demonstrating that new behaviour patterns
could be shaped by rewarding desired responses. In other words, learning,
he maintained, depends on what happens after a new behaviour is exhiblted.
The procedure of providjng rewards or satisfying consequences after a
response is referred to as reinforcement. The basic principle of re~nforcement
theory is that behaviours that are followed by reinforcement are more likely to
recur in the future, implying that they are learned.
Also fundamental to reinforcement theory is the not~on that
complex skills can be broken down into clusters of simpier ones. Each sub-
sk~ll can be learnt one at a time, if the subject receives reinforcement after
each correct response
22 Theoretical Overview
Simple behaviourist theory however cannot explain common,
but complex behaviours such as imitation and demonstrations of empathy,
both of which involve representation and wh~ch occur without apparent
reinforcement.
The Cognitive Perspective
Cognitive theorists claim that it is possible and necessary to speculate
about mental processes. They maintain that we cannot design more effective
instruction for intellectual skills until we understand or at least have a theory
about mental processes. For Piaget (1 956), children's thin king develops
through the dynamic interaction of two processes - assimilation in which new
information IS taken into their existing concepts and accommodation in which
these concepts change to fit new information. These two features of Piaget's
theory have influenced a good deal of thinking in contemporary
developmental psychology. Piaget's work has been criticised on the grounds
that the rather artificial and socially awkward situations in wh~ch he observed
children led him to underestimate children's thinking. Recently, however,
newly translated work provides strong evidence of Piaget's recognition of the
role of social encounters on development (Smith, 1 995).
The ~deas of the American Psychologist Bruner (1966) are
similar to those of Piaget In many ways. He described three increasingly
powerful ways of representing the world (Bruner, 7 966).
Enactive representation, in which thought is based only on actions.
23 Theoretical 0 vervje w
Y Iconic representation, in which the child can form and use images of
objects without the actual objects themselves having to be present.
Y Symbolic representation in which the child can use and think in times of
symbols such as words, which do not necessarily have anything in
common with what they represent.
Lev Vygotsky (1 896-1 934) proposed that children develop
through social interactions particularly those involving language, wh~ch they
then rnternalise to form their own concepts. Teachers and other adults play a
major role in collaborating with children in learning relationships One of
Vygotsky's best known developmental concepts is what he called the Zone of
Proximal Development (ZPD) which refers to the difference between what children
can do alone and what they can do with help from an adult (Vygotsky, 1961).
One of the most popular and influential discussions of different
ways of thinking was proposed by Gardner in 1983. Gardner suggested that
there might be eight such intelligence - linguistic, mus~cal, special, logical-
mathematical, bodily-kinesthetic, interpersonal, intrapersonal and naturalistic.
However, he was careful to point out that "these intelligences are fjctions and
most useful f~ctions" - for discussing process and abilit~es that are cont~nuous
with one another (Gardner, 1983).
In constructivist teachrng, rather than receiving knowledge as in
tradit~onal approaches, students are expected to construct it through activity in
a stimulating env~ronment.
Theoretical Overview
More recently, Donaldson ( 7 992) characterised children's
thought as moving from 'point mode' to 'line mode', construct mode' and
finally to 'transcendent mode'. In 'point mode', the infant is restricted to
thinking in the here and now, whereas with 'line mode', the child's thought can
move backwards and forwards in time. With 'construct mode', there is
generalisation taking place, though still in concrete terms until finally with
transcendent mode, the limitations of space and time are overcome
Recent studies by Sylvester (I 995) suggest that human bra~n
consists of tens of b~llions of cortical neurons that regulate cognit~ve thinking
activities and even more glial cells that support and feel the neurons. As the
brain builds more branches and more connections can be made When
dendrites branch, abstract thinking increases. Thinking is a dynamic process.
If the brain is not used, the dendrites do not branch out. Conversely, more
dendrites or branches can grow on the brain, when it is stimulated.
The Socio - Psychotogical Perspective
Social psychology brings a third perspective to analysing
strategies of instruct~on. What is important from this perspect~ve is the social
organisation of instruction
Social learning theory was put forward by Bandura and Walters
(1963) and the~r colleagues. Social learning theory overcomes the problems
of s~mple Skinnerian behaviourism by incorporating cognitive constructs,
notably identification and imitation which enable it to deal with more complex
developmental phenomena such as sex typing. Social psychologists have
25 Theoretical 0 vervie w
found that achievement tends to be higher in a co-operative environment
(Johnson, 1981 ). The importance of emphasising collaboration among
students is also supported by the cognitive theorists; they claim that
knowledge and skills become useful and take on real personal meaning when
they are attained through a process of social negotiation.
2.3 TECHNOLOGICAL BASES OF INSTRUCTIONAL STRATEGIES
Traditional instructional strategies must be reassessed in the
light of the increasing influence of technology, especially information and
commun~cation technology (ICT). The effective use of ICT encourages a
more flexible and student-centred environment Advances in ICT have
contributed to a movement away from a behaviourist learning theory to a
construct~vist learning theory. ICT developments and new research on the
effectiveness of technology-enhanced learning require the continuous
planning of technology - enhanced learning strategies or adjustments to
existing strategies (Laurillard, 2000).
Modern Instructional strategies can be broadly classified under
the following heads.
2.4 STRATEGIES OF INSTRUCTION THAT EMPHASISE REINFORCEMENT
OR FEEDBACK AND INDlVfDUAL PACING
a. Proqrarnmed Instruction: It is teachingllearning pattern designed to
provide reliable effective ~nstruction to each learner through the
appl~cation of reinforcement theory (Heinich, 1993) The programme
consists of small units of information requiring practice, followed by
26 Theoretical Overview
feedback. It atlows individual pacing (Skinner, 1954). The main styles of
programming are linear or extrinsic programming, branching or intrinsic
programming and mathetics.
b. Proqrammed Tutoring: It is a one-to-one method of instruction in which
the decisions to be made by the tutor are programmed in advance in the
form of carefully structured printed instructions. It shares with
programmed instruction, the characteristics of individualised pacing,
active learner response and immediate feedback. The use of a live tutor
as a mediator adds immensely to the flexibility of the system.
c. Prosrammed Teachina The salient features of programmed teaching
are:
Scripted Presentations
Small-group instruction
Unison responding by learners
Cues given by teacher
Rapid pacing
Reinforcement and correction procedures
d. Instructional Modules: It is the term for any freestanding, self-
contained and self-instructional unit. Essential components of a module
include rationale, objectives, entry test, muitimed~a mater~als, learning
activities, self-test and a post test. To be utilised as a free stand~ng
lesson, a multimedia kit could be placed in a learning centre along with a
27 Theoretical Overview
statement of purpose and a pre-test and a post-test; that total package
could be considered a module.
e. Personalized System of Instruction (PSI): PSI could be described as a
technology for managing instruction. The organisational framework of
PSI emphasises individual pacing, the mastery of lessons and regular
person-to-person contact with a proctor (Keller, 1968). In PSI
classrooms, students work individually at their own pace using any one
of a variety of instructional materials - a chapter in a book, computer-
assisted instruction, a video cassette, a sound filmstrip, a programmed
booklet and so on.
f. Audio-Tutorial Systems: The most visible aspect of audio-tutorial
systems is the study carrel equipped with specially designed audiotapes
that direct students to various learning activities. The taped presentation
is not a lecture, but a tutorial conversation by the instructor des~gned to
facilitate effective co~nmunication. A live instructor is nearby to assist
students when needed. Learners proceed at their own pace; sessions
begin and end to sui t students' schedules, Individualisation and
personalisation are critical elements in this sort of system.
Strateqies of Instruction Based on Multimedia
(a) Multimedia Packaqes. The multimedia concept involves more than
using multiple media for a given instructional purpose (Heinich, 1985).
Multimedia packages arouse interest because they are multisensory
They give the concrete referents needed to build a strong format~on for
28 Theoretical Overview
more abstract mental abilities. The main purpose of a kit is to give
learners a chance at first hand learning - to touch, to observe, to
experiment, and to decide. They may contain flash cards, student
