ABSTRACT
The orientation of this book is developmental, a term used in many different ways by those of us interested in children. Most basically, the term applied has its origins in biology. Recall that Piaget was, first, a biologist. The construct development is also of interest to those of us interested in human development, psychology, and education. Even at the level of statewide educational policy, the notion of development is evoked: Some states have developmental kindergartens, classrooms for children not promoted to first grade from kindergarten.
