Constructivism is a set of assumptions about the nature of human learning that guide constructivist learning theories and teaching methods of education. Constructivism values developmentally appropriate teacher-supported learning that is initiated and directed by the student.

It is easy enough to formulate simple catchy versions of the idea of constructionism; for example, thinking of it as "learning-by-making." One purpose of this introductory chapter is to orient the reader toward using the diversity in the volume to elaborate--to construct--a sense of constructionism much richer and more multifaceted, and very much deeper in its implications, than could be conveyed by any such formula.
