Which concept describes the difference between what a learner can do independently and what they can do with guidance?

• A. Scaffolding
• B. Equilibration
• C. Zone of proximal development
• D. Assimilation

Answer: (C)

The idea being tested is the range of tasks a learner can handle with help versus on their own. The zone of proximal development describes the gap between what a learner can do independently and what they can do with guidance or support. It’s this space that shows where learning is most effective because with prompts, hints, modeling, or collaboration, a student can reach higher levels of understanding than they could alone. Scaffolding is the kind of support provided within that zone and is gradually reduced as competence grows. The other terms describe different ideas—not the gap between independent and guided ability: equilibration is about balancing new and existing ideas, and assimilation involves fitting new information into existing mental schemas.
