Explanation:

Zone of proximal development: In psychology, the term "zone of proximal development" is also denoted as ZPD, and was proposed by one of the most influential psychologist named Lev Vygotsky.

According to Lev Vygotsky, ZPD is described as the phenomenon in which the difference between a particular listener's or student's capability to carry out a specific task independently vs. to carry out the task with an elder's or teacher's guidance is being governed.
