Which educational theorist is credited with the zone of proximal development concept?

• A. Piaget
• B. B.F. Skinner
• C. Lev Vygotsky
• D. Erik Erikson

Answer: (C)

The zone of proximal development is the idea that learning happens best when a learner tackles tasks just beyond what they can do alone, with support from someone more knowledgeable. This concept is credited to Lev Vygotsky. It highlights that social interaction and guidance shape learning: a teacher, peer, or more capable person provides scaffolding—models, prompts, hints, or step-by-step help—that enables the learner to perform and internalize new skills within that zone. As competence grows, the support is gradually removed, and the learner can do the task independently. This perspective contrasts with Piaget’s focus on independent discovery and stages, Skinner’s emphasis on reinforcement, and Erikson’s psychosocial development, which do not center on guided learning in the same way.
