Social constructivism is a theory developed by Lev Vygotsky that asserts social learning precedes development. Vygotsky believed that social interaction and communication with more knowledgeable others helps children develop new cognitive structures called the Zone of Proximal Development. According to Vygotsky, learning occurs through social interaction and communication first on an interpersonal level then on an intrapersonal level. Vygotsky's theory emphasizes that social learning should involve collaboration between students and teachers to actively construct meaning.
