Which concept defines the difference between what a child can do alone and what they can do with help?

• A. Scaffolding
• B. Zone of proximal development
• C. Guided participation
• D. Intersubjectivity

Answer: (B)

Zone of proximal development is the difference between what a child can do alone and what they can do with help. This idea, from Vygotsky, emphasizes learning that occurs through social interaction with a more capable partner who provides guidance and support. The support, or scaffolding, is intentionally adjusted and removed as the child grows more competent. That makes the ZPD the best fit because it specifically defines the learner’s current independent ability versus the potential they can reach with assistance. Related ideas like scaffolding describe the help itself, while guided participation and intersubjectivity are broader social-learning concepts, but they don’t pinpoint the gap between independent and assisted performance as clearly.
