Who introduced the Zone of Proximal Development?

• A. Jean Piaget
• B. Sigmund Freud
• C. Lev Vygotsky
• D. Albert Bandura

Answer: (C)

The Zone of Proximal Development describes the range of tasks a learner can perform with guidance and collaboration but not yet on their own. Lev Vygotsky introduced this idea, showing that learning is a social process where a more knowledgeable other provides scaffolding—support tailored to the learner’s current level—that helps them reach higher understanding. As guidance is gradually faded, the learner gains independence and mastery. This emphasis on social interaction and guided participation sets ZPD apart from other theories: Piaget focused on development through independent discovery and stages, Bandura emphasized learning through modeling and imitation, and Freud studied psychosexual development. By working within the ZPD, educators tailor support to just beyond what the learner can do alone, helping them progress more effectively.
