Which theorist introduced the Zone of Proximal Development (ZPD)?

• A. Sigmund Freud
• B. Lev Vygotsky
• C. Jean Piaget
• D. B. F. Skinner

Answer: (B)

The Zone of Proximal Development captures how learning happens best with supportive social guidance. It describes the range between what a learner can do on their own and what they can do with help from someone more knowledgeable, such as a teacher, parent, or more capable peer. With that targeted support, the learner can handle tasks just beyond their independent ability, and over time the guidance is gradually removed as competence grows. This idea sits at the heart of Lev Vygotsky’s sociocultural theory, which emphasizes that cognitive development is shaped by social interaction and cultural tools. The practice of scaffolding—providing just enough help and then fading it as the learner improves—illustrates how instruction can be tuned to this zone. The other theorists—Freud with psychosexual development, Piaget with stages of individual cognitive development, and Skinner with behaviorist reinforcement—offer important perspectives, but none introduced the concept of a learning zone that hinges on guided social interaction.
