The zone of proximal development refers to the gap between a child's ability to solve a problem: on his own versus after being taught.

True.

Explanation:

The Zone of Proximal Development (ZPD) is a part of development of children which include a wide range of processes including - psychological, emotional and volitional. It was first introduced by a psychologist Lev Vygotsky (1896-1934), and afterwards fully developed by Jean Piaget (1896-1980).

It is interpreted as a distance between what a learner can do without help and what can do with a support from a knowledgeable adult. It is believed by some that the role of education is to give children valuable experiences that are within their zone of proximal development, therefore encouraging and advancing their individual learning such as skills and strategies.
