In this volume of the "Ways of Knowing in Science Series", Rodger Bybee presents 15 years of his essays on science education, that develop several major themes: the need for the curriculum to take into account the accelerating pace of scientific research and discovery; the increasing irrelevance of the traditional boundaries among the sciences; the significant changes to civilisation brought about by scientific advancement; the growing realisation that the competitive position of any country in today's global economy rests primarily on the production and use of scientific knowledge and technologic products; and the necessity of scientific and technologic literacy for all citizens. As Bybee points out, the American educational community has not yet successfully redefined its goal to conform to new realities, a prerequisite to any meaningful transformation of the science curriculum. The book is suitable for use in graduate courses in science education, undergraduate methods courses, in-service science education teachers' courses, and for use by professors and researchers of science education, curriculum planners and school leaders.
