The correct answer is Zone of Proximal Development
Zone of Proximal Development is the distance between what the child can do independently and what he can do in an assisted way or with the help of the teacher, parents or another child at a more advanced level of development.
In order for the teacher to be able to identify the zone of proximal development of his students, he must also know the concepts of real development, which is the one already consolidated by the child, and potential development, which concerns what the child is able to accomplish in an assisted manner. The zone of proximal development is the gap between these two levels of development.
