Bruner's theory is a constructivist and cognitive theory of development. according to Bruner- child learns in three levels- Enactive, Iconic and symbolic. that means first the child learns through physical actions, then learn through pictures, which later he/she codifies into symbols in the brain. so the process of cognition is important here.
Bruner suggests that any age group child can be taught any level of learning, provided we organize it in the above said levels of learning. scaffolding and discovery learning are some of the concepts emphasised and formulated by Bruner.
Thus in education system we can frame the concepts at experiential, image and symbolic levels and the children according to their cognitive development, will learn any concept easily.
Bruner's theory supports for flexibility and creativity in desiging the teaching material, so that chiildren with all levels can benefit anf learn easily.
