3.1 INTRODUCTION
In Unit two, we have discussed about various approaches to learning. After going
through the comparative perspective of various approaches, you must have
realized that constructivism has its distinguished relevance in learning. In last
one decade, Indian school education has transformed a lot and there is major
emphasis on constructivist teaching learning or we can say, promoting learning
for construction of knowledge by learners themselves. In present unit, we will
discuss various constructivist approaches and identify the essential elements for
creating a conducive learning environment. We will also discuss characteristics
of a constructivist classroom, which will help you to transform your class into a
constructivist class. The unit will end with reflections on how learning takes
place in a constructivist classroom.
3.2 OBJECTIVES
After going through this unit, you will be able to:
• understand various constructivist ideas towards learning;
• identify the essential elements from various constructivist’s ideas,
• create a constructive learning environment in your class, and
• practice teaching-learning in constructivist discourse.

3.3 CONSTRUCTIVISM: AN INTRODUCTION of Knowledge
Activity 1
Define constructivism in your own words, keeping the basic assumptions
in your mind.

From above discussion, you must have understood that constructivism emphasizes
on the active role of the learner in developing understanding and making their
own meaning based on their previous knowledge and experiences in a new
situation.
Thus, Piaget emphasized on an active learner who can observe, act, modify,
manipulate, transform and construct own meaning of an object or event. But it is
possible when learner is in appropriate developmental stage. You must have got
an idea of all the four developmental stages of children as proposed by Piaget,
i.e. sensorimotor, preoperational, concrete operational and formal operational
in Unit 2.
Piaget proposed that learning takes place through some basic tendencies. He
named these tendencies as Organization, Adaptation and Equilibrium. He
proposed that some mental structures ‘schema’ develops based on perception
and experience, these ‘schema’ are organized through the processes of
assimilation and accommodation and equilibrium emerges.

Learning: Perspectives and
Approaches Ms. Neha is a science teacher in a secondary school of Uttarakhand. In
her class of classification and characteristics of leaves, following has
happened.
The moment Ms. Neha entered in the class, children were playing and they
saw their teacher with various types of branches and twigs with leaves in
her hand. She handed over all branches and twigs to children and asked
them to do something interesting.
Children distributed those amongst them by making six groups and tried
many things like placing them in form of a garden, few tried to collect
leaves from branches and arranged according to size, shapes, etc. One
group decides to identify the name on plants, which have those different
leaves.
After 15 minutes, she asked children to tell, what they have done and why.
Following were the responses:
Group 1 : Ma’am, we made a garden where plants of short height and
small leaves are on sides while plants with long leaves and
higher are in middle. We do so because all leaves need proper
light and if we place big plants/tress on side, it will difficult to
smaller plants to get proper light.
Group 2 : Ma’am, we tried to identify plants and from where these leaves
have been taken, because different kind of plants has different
types of leaves.
Group 3 : Ma’am, we made different groups of leaves based on their
size and shapes.
Group 4 : We arranged leaves in the way these are attached to the branch.
We found few leaves are directly linked to main branch while
few leaves are in a group of three or five or more on a single
strand and this strand is attached to the branch. We also noted
that few have a base while few directly emerge from branches.
Group 5 : Ma’am, we tried to identify the leaves and linked it with the
knowledge givenby our grandparents and parents about the
uses of these leaves. We found few are used as vegetables; few
as medicine while few as decorative.
Group 6 : We arranged the leaves based on the distribution of veins in
leaves. In few leaves it is like a matrix while in some it is like
parallel lines.
She was very impressed with the variety of thoughts presented by children.
Though she was aware that they don’t know the technicalities of
classification of leaves based on various parameters but they knew many
things which she wanted to explain.
She put few cards in front of class having some terms like: usage, shape,
venation, size, adaptation, etc. and asked groups to choose one card which
suits their work. She was amazed to note that most of groups have chosen
the appropriate card. It has helped her to introduce the concept of
classification of leaves.

Let us try to analyze and find out how the terms proposed by Piaget are fit in this Learning for Construction
of Knowledge
context.
Schema: Colour, size, use, shape, place in garden are certain schemas, which
different children have in their mind based on their observation, perception and
experience.
They tried to organize their knowledge and used their existing schema to fit in
the situation given to them; this is called assimilation, i.e. the process of
explaining and understanding new information with the help of already existing
schemas.
When few of them found the leaves they were not aware of and they used their
knowledge to understand and fit in new leaves in an articulate group i.e. they
adopted, modified or adjust their already existing schema to understand new
things/information/situation, this is called accommodation.
When Ms. Neha gave them some cards and they chose one, which was most
appropriate to their way of classifying the leaves, they were satisfied. Getting
satisfactory understanding of information by using process of assimilation
and/or accommodation is equilibrium.
Piaget also proposed that if satisfaction does not occur by applying schema through
process of assimilation or accommodation, it results in disequilibrium, which
motivates the learner to search and find the solution which can give satisfaction.
Activity 2
Identify a real classroom situation in your class. Analyze it in relation to
following terms:
Schema(s) ........................................................................................................
.......................................................................................................................
Assimilation ..................................................................................................
.......................................................................................................................
Accommodation ...........................................................................................
.......................................................................................................................
Situation of equilibrium: ..............................................................................
.......................................................................................................................
.......................................................................................................................
Situation of disequilibrium:
.......................................................................................................................
.......................................................................................................................
In above example, you can see how the child move from lower limit to upper
limit in ZPD and enjoy successful learning with the help of more experienced
person.
To use the concept of zone of proximal development, you can follow a step by
step process, which will help learners to construct their knowledge:
• You should identify the already known to the learners. After knowing about
it, you should plan the situation where a new concept can be developed by
linking it with learners’ prior knowledge.
• While planning the less, you should design such situation and activities,
where most of learners can reach success. You should also identify few points,
where the learners need your support or peer interaction.
• Design variety of situations based on various realistic contexts, because all
learners will not learn in same way as well as their prior knowledge is not
similar.
• Ask learners to compare what they learnt and what was already known before
the task. Encourage them to enjoy their new learning and express their
56 feelings.
Tharpe & Gallimore (1988) also expressed that ZPD is a four-stage process: Learning for Construction
of Knowledge
Stage 1 : Assistance provided by More Knowledgeable Others (MKO’s) or
capable peers
Stage2 : Assistance provided by self
Stage 3 : Automatization through practice
Stage 4 : De-automatization; recursiveness through the previous three stages
Vygotsky is of the view that it is possible through any social interaction i.e.
interaction with teacher, interaction with peer, interaction with parents, friends
or people in community. He called these the ‘buds’ or ‘flowers’ of development,
to distinguish them from ‘fruits’ of development, which the child already can
accomplish independently. (Vygotsky, 1978). One more concept linked with ZPD
is of Scaffolding, i.e. a technique to provide right kind of support in right
amount at right time to increase child’s competence. It will be discussed in
details in section 3.5.1.
Vygotsky argued that there is a need to assess child’s ZPD in place of IQ. Before
beginning instruction, more experienced person should assess a child’s ZPD
through giving tasks with varying difficulties to assess, from where teaching-
learning should begin.

He said that a teacher should create an environment and help learners in sharing
the materials. Learners should develop their own meaning from material. A teacher
should appreciate what a learner is learning and tell them that their understanding
is never complete. Learning should be an interactive process. He defined learning
as:

3.6.1 Scaffolding
We have already discussed a little about scaffolding while discussing about ZPD
in section 3.4.3 as well as in 3.4.4 while discussing ideas of Bruner. Idea of
scaffolding is a key concept in social constructivism.
When a teacher starts supporting learner initially for learning, and gradually
reduce the support till the learner reachesa situation, where s/he can develop his/
her own meaning and understanding independently. Teacher is scaffolding the
learner.
Let us read the following case, and try to develop a clear understanding about
scaffolding.
Read and analyze the following case and try to answer the questions.
John, a Geography teacher in a rural school of Kerala, was in a class of
mapping. Learners were expected to read maps as well as draw a
geographical map and indicate important places, rivers, etc., in the map. It
is a class with learners from diverse backgrounds, so he tried following
strategies:
62
Learning for Construction
1) For one group of learners coming from same village, he asked to draw of Knowledge
the path from their home to school on a sheet and mark important
places, or something can be used to describe right path.
2) For second group, he gave the map of Kerala state and asked to identify,
which they felt was interesting in the map and should be the part of
their map.
3) In third group, he asked to discuss about various important places,
rivers, etc. known to them and use their knowledge to develop a map.
Can you reflect on following questions?
• Why John gave three different tasks in same class?
• Why to one group John gave map of Kerala but not to the other group?
• Do you think all groups need similar support from John?
• Which group needs more scaffolding then others?
From above case, you can draw a conclusion that scaffolding is not only a
technique to support learner to achieve their goals but it also helps in filling the
‘learning gaps’ i.e. what a learner has learnt and what was expected to learn.
Here are few common examples of scaffolding, which various teachers practiced
in their classrooms:
Activity 5
Identify few situations from your classroom, where you think scaffolding
is required. Write down these situations and plan a scaffolding strategy,
which is best suited to the situation. Apply it and see the results. Prepare a
report on this activity.
