Constructivism in Education [PDF ebook] 

Unique in offering a multidisciplinary perspective on key issues of alternative epistemologies in education, this collection includes contributions from scholars in family therapy, epistemology, and mathematics, science, and language education. These respected researchers were brought together to develop the theme of constructivism as it applies to many diversified fields. This book examines key distinctions of various constructivist epistemologies, comparing and contrasting the various paradigms. Each section provides both keynote positions on a particular alternative paradigm as well as critical comments by respondents regarding that position. Several chapters also present a synthesis of the alternative epistemological perspectives.
