Answer:
In sociocultural theory, a metaphorical area or "zone," surrounding a learner that includes all of the skills, knowledge, and concepts that a person is close ("proximal") to acquiring but cannot yet master without help is the zone of proximal development.
Step-by-step explanation:
The zone of proximal development (ZPD) represents the scope of skills that a person can carry out with the help of external people, but he/she is unable to do by himself/herself. These skills are known as "proximal" because the person is proximal to completely dominate them but still depends on somebody else for guidance. The individual also has to practice more to become independent.
