It is also known as genetic epistemology .Learner individually construct meanings and knowledge for themselves as they learn building of meaning and knowledge that occurs in people’s mind when they are learn, how knowledge develop in human organism.

STAGES OF DEVELOPMENT   

1)      Sensory motor stage

2)      Pre- operational stage

3)      Concrete operational stage

4)      Formal operational stage

SENSORY MOTOR STAGE(0-2 Years)      

Schema, assimilation, accommodation and equilibration, adaptation

Squeeze a rubber duck to hear it quacks

Find other ways to make it quack again.

Searching the thing when we hide it.

PRE OPERATIONAL STAGE(2-7 Years)

Operations takes places.

Mental manipulations and transformations.

Language development. Eg : Bottle is considered as a source of milk.

CONCRETE OPERATIONAL STAGE (7 -11 Years)    

Inductive and deductive reasoning.

Flexibility in thinking.

Understanding of the principle of conservation

Classification

Transitivity – recognizes  Recognizing ability. Eg:- Neethu is taller than Divya and Divya is taller than Asha.who is taller?

Reversibility of thoughts .Eg;- Agirl who has a sister now clearly realize that her sister is  also has a sister.

Piaget explains the concept of reversibility which is an intellectual ability that develop only at later stage.

                   FORMAL OPERATIONAL CHANGE(12-15 Years)

Ability to deal with abstraction.

Hypothetic deductive reasoning

Systematic approach to solve problems.

Use of abstract rules

Ability to transfer knowledge.

EDUCATIONAL IMPLICATIONS

For construct ability based curriculum

Providing learning experience in tune with the mental ability of the child

Providing leraning task

Provide importance to child centered education.
