Concept:Vygotsky’s socio-cultural theory stresses that learning happens through social interaction and guided support from more knowledgeable others.
Explanation:Vygotsky proposed scaffolding — temporary assistance like hints, leading questions, or demonstrations — to help a child solve problems within their Zone of Proximal Development (ZPD).
This support gradually fades as the child becomes more independent.
Option A is wrong because Vygotsky believed help is crucial for new tasks.
Option C is incorrect because he emphasized interaction with adults and peers.
Option D is not part of his theory; he did not focus on material rewards.
Only option B matches his idea of scaffolding, where hints and leading questions guide learning without giving direct answers.
Answer:B. children should be scaffolded while solving problems by giving them hints or asking leading questions.
