Vygotskyâs Social Development Theory. Vygotskyâs Social Development Theory is the work of Russian psychologist Lev Vygotsky (1896-1934), who lived during Russian Revolution. Vygotskyâs work was largely unkown to the West until it was published in 1962.Vygotskyâs theory is one of the foundations of constructivism.It asserts three major themes:ummary: Social Development Theory argues that social interaction precedes development; consciousness and cognition are the end product of socialization and social behavior. Originator: Lev Vygotsky (1896-1934).
(p57). A second aspect of Vygotsky's theory is the idea that the potential for cognitive development depends upon the zone of proximal development (ZPD): a level of development attained when children engage in social behavior.Full development of the ZPD depends upon full social interaction.ygotsky's theory is complementary to Bandura's work on social learning and a key component of situated learning theory as well. Because Vygotsky's focus was on cognitive development, it is interesting to compare his views with those a constructivist (Bruner) and a genetic epistemologist (Piaget).
