Answer:
Zone of Proximal Developmment.
Explanation:
Vygotsky refers to Zone of Proximal Development as the difference between skills or tasks that adolescents can accomplish alone and those they are capable of doing if guided by an adult or a more competent peer. This refers to the difference between what an adolescent can achieve independently and what can be achieved through a more competent peer's guidance. This guidance must allow the adolescent to develop his or her skills.
