Theories and Practices on the Reform of Science Education in U.S. A. --specially on the construction of science curriculum in elementary school--

Abstract

In the reform of science education in U.S.A., Phenix's key concepts theory and Bruner's structure theory play an important role. But in practices and studies of the new science program development there are a great diversity of contents and organizations. ESS, SCIS, and AAAS projects are discussed comparatively in light of the theories.
