 VYGOTSKY THEORY OF COGNITIVE DEVELOPMENT

                                     

 this theory is also known as the socio-cultural theory of development.

 vygotsky said that development and learning take place because of cooperative process between  the child and  society.

first comes language then comes thought .

Knowledge is internalization of social activity.

learning is based on interaction between child and adult or peer.

He supported collaborative problem solving  between students.

Zone of Proximal Development (ZPD)

This is the Vygotskian concept that explains the mechanism of cognitive development. 

ZDP is actually the gap between actual competence level (what problem level a student is able to  solve on his own) and the potential development level (what problem level could she solve in  guidance of a  more knowledgeable person ).

ZDP can be simply understood as what a child can do on his own and what he can do with the help of more knowledgeable other. 

Scaffloding -

this is known as the help or temporary help provided by the teacher to the child in the process of learning. 

the teacher becomes helpful tool for the child in the process of zone of proximal development.

Self talk /Private speech/Internalization -
