Concept:Vygotsky’s sociocultural theory emphasizes that learning happens through social interaction and that a teacher should act as a scaffold—giving temporary, individualized support to help students correct their own mistakes.Explanation:Scaffolding means providing the right kind of help at the right time to increase a student’s competence. It is a temporary support that allows the child to learn from errors under guidance. The teacher does not simply give answers or ignore misconceptions. Instead, the teacher creates opportunities for students to identify and fix their mistakes themselves. This builds independence and deeper understanding. Vygotsky’s Zone of Proximal Development also supports this idea, where a more knowledgeable person helps the learner reach a higher level. Therefore, a teacher’s role is to scaffold students so they can correct their errors on their own.Answer:D. scaffold students to correct their errors themselves.
