Social Construction of Knowledge
Vygotsky's central claim is that higher mental functions originate in social interaction and are then internalised. His 'general genetic law of cultural development' states that every function appears twice: first on the social (inter-personal) plane, between people, and later on the individual (intra-personal) plane, inside the child. A child first counts aloud with a parent's help, then later counts silently in their own head. Knowledge is therefore co-constructed — built together with others — not discovered alone. Culture supplies the 'tools' (language, number systems, symbols, ways of remembering) that shape how a child thinks, which is why children in different cultures develop somewhat different cognitive skills. This is the heart of social constructivism and the basis of collaborative, dialogue-rich classrooms.
