This timely volume provides a constructivist interpretation of developmentally appropriate curriculum in early childhood education. Rheta DeVries, one of the founders of constructivist early education, and her colleagues provide the theoretical rationale and practical advice for conducting specific activities in the classroom. Descriptive vignettes are used to show how children's reasoning and teacher interventions are transformed in the course of extended experience with a physical phenomenon or group game. Throughout the book, constructivist teaching is illustrated and contrasted with the approaches found in three other classroom types.
