The work of Jean Piaget has become the foundation of current developmental psychology and the basis for changes in educational practice. David Elkind, author of The Hurried Child and Miseducation, and a student of Jean Piaget, explores the roots of Piaget’s work and outlines important vocabulary and concepts that structure much of the study of child development. Using both archival film of Dr. Piaget and newly shot sequences of Dr. Elkind conducting interviews with children of varying ages, this film presents an overview of Piaget’s developmental theory, its scope and content.
