Among the latest trends in moral educational theory, several authors have suggested that a sociocultural approach to moral education is an improvement over the dominant cognitive-developmental and character educational paradigms. This approach draws its inspiration from the work of the Russian psychologist Lev Vygotsky. In the 1920s, Vygotsky attempted to reconstruct psychology to overcome the false dichotomy psychologists had posited between the individual and the environment. This genre of sociocultural theory has come to be known as activity theory. Despite its aims, however, activity theory never overcame the dualism of individual and environment. My contention is that Dewey's moral psychology is more adequate to that task, and thus is a more appropriate foundation for developing moral educational policy and practice.
