Answer:
Zone of Proximal Development is the level at which child cannot fully perform a task independently, but can do so with assistance of someone more competent.
Step-by-step explanation:
The 'zone of proximal development' (ZPD) is the range of tasks that a person can do with assistance but is not pro in doing it independently. It is basically the difference between what an individual can do without help and what he can do with guidance.
These skills or tasks are called "proximal" because the person is close to mastering them. If a support is provided to complete tasks, then the person is encouraged to become independent and this leads to his growth.
