Compare and contrast Jean Piaget's theory with that of Lev Vygotsky.

In comparing Vygotsky's theory to Piaget's theory,it is clear that Vygotsky places a strong emphasis on sociocultural context while Piaget does not.Piaget is a cognitive constructivist while Vygotsky is a social constructivist.Piaget places a strong emphasis on stages: whereas,there are no stages in Vygotsky's theory.The key processes for Vygotsky's theory are the zone of proximal development,language and thought,and the tools of culture.Piaget,on the other hand,emphasizes schemas,assimilation,accommodation,hypothetical-deductive reasoning,and classification.Piaget believed that language had a minimal role in cognition while Vygotsky believed it was very powerful in shaping thoughts.
