The work of Lev Vygotsky is increasingly cited as we reconsider the theory and practice of constructivist education. This program introduces the life, vocabulary and concepts of Lev Vygotsky. The program illustrates four basic concepts integral to his work: Children construct knowledge, learning can lead development, development cannot be separated from its social context, and language plays a central role in cognitive development. Elena Bodrova brings an easy familiarity to these concepts. Deborah Leong's commentary and the lively classroom examples enable students, teachers in training, and classroom teachers to incorporate these concepts into their understanding of child development.
