Two leading science educators provide a comprehensive, state-of-the-field analysis of current trends in the research, policy, and practice of science education. This book offers valuable insights into why gaps in science achievement among racial, ethnic, cultural, linguistic, and socioeconomic groups persist, and points toward practical means of narrowing or eliminating these gaps. Lee and Buxton examine instructional practices, science curriculum materials (including computer technology), assessment, teacher education, school organization, federal and state policies, and home-school connections. The book synthesized the emerging body of research in the field of science education and its application to practice and policy and features an analysis of major science education initiatives, interventions, and programs that have been successful with non-mainstream students.
