L.S. Vygotsky, the renowned Russian psychologist, argued that the true
test of any scientific theory is not the contribution it makes to our
understanding of the object of study but the extent to which it improves
the concrete practical activities of people, including those that take
place in educational settings. The fourteen original chapters included
in the present volume document innovations in second and foreign
language teaching that are rooted in Vygotsky's theory of cognitive
development. Researchers and language teaching practitioners will find
implementations at the classroom and programmatic levels of Vygotskian
principles and concepts, including cognitive mediation, the zone of
proximal development, activity theory, internalization, verbalization,
and materialization.
