Concept:Vygotsky's sociocultural theory says learning is both constructive (children build their own knowledge) and collaborative (they learn through social interaction).Explanation:Vygotsky emphasized that society and culture are essential for cognitive development. Children do not learn alone; they learn by interacting with more knowledgeable others (MKO), like teachers or peers. This interaction happens in the Zone of Proximal Development (ZPD) where a child can achieve more with guidance. Language plays a central role, and knowledge is actively constructed, not passively received. Thus, learning is a constructive and collaborative process, not just memorization, independent discovery, or stimulus-response association.Answer:C. learning is constructive as well as a collaborative process.
