The achievement gaps in science and the under-representation of minorities in science-related fields have long been a concern of the nation. This book examines the roots of this problem by providing a comprehensive, 'state of the field' analysis and synthesis of current research on science education for minority students. Research from a range of theoretical and methodological perspectives is brought to bear on the question of how and why our nation's schools have failed to provide equitable learning opportunities with all students in science education. From this wealth of investigative data, the authors propose a research agenda for the field of science education - identifying strengths and weaknesses in the literature to date as well as the most urgent priorities for those committed to the goals of equity and excellence in science education.
