Explanation:
Zone of proximal development is the concept developed by the Soviet psychologist, Lev Vygotsky.
It is described as the cognitive, emotional, and volitional psychological development of children. Therefore, this zone is defined as the distance between the ability of the children to perform certain activities without help and perform other tasks with the help and support of a knowledgeable adult.
