In Diversity and Equity in Science Education: Research, Policy, and Practice (Teachers College Press, 2010) Okhee Lee and Cory Buxton provide a comprehensive, state-of-the-field analysis of current trends in the research and practice of science education.  This book offers valuable insights into why gaps in science education achievement among racial, ethnic, cultural, linguistic, and socioeconomic groups persist, and points toward practical means of narrowing or eliminating these gaps.  The authors examine instructional practices, science curriculum materials, assessment, teacher education, school organization, state and district policies, and home-school partnerships.  For each topic, they provide detailed descriptions of relevant research projects and the effective teaching and learning practices that have emerged from that work.  Special focus is placed on the unique learning needs of English language learners.
