Which theorist is associated with the Zone of Proximal Development?

• A. Erik Erikson
• B. Jean Piaget
• C. Albert Bandura
• D. Lev Vygotsky

Answer: (D)

Zone of Proximal Development is the range between what a learner can do independently and what they can do with guidance and support from a more knowledgeable other. It shows how teaching, feedback, and collaborative interaction help bridge gaps that the learner can’t cross alone, with scaffolding that’s gradually removed as competence grows. This idea was developed by Lev Vygotsky, who viewed learning as a social process shaped by culture and language, and who introduced scaffolding as the temporary support that enables achievement beyond independent ability. Other theorists linked to development imagine different mechanisms—Piaget emphasized individual discovery through stages, Erikson focused on psychosocial crises across the lifespan, and Bandura on social learning and self-efficacy. The Zone of Proximal Development remains central to instructional design because tasks should be challenging yet achievable with appropriate guidance.
