I learned a lot from its papers, several of which are already on the reading list for my...courses.

In fact, read it from cover to cover."—British Journal of Educational Psychology"...an admirable job of presenting the diversity and scope of research on coneptual development....With this collection, the editors have provided both an impetus to revisit basic questions in the field as well as an excellent resource for addressing them."—Human Development
