The Anatomy of Achievement Gaps offers a critical analysis of underachievement problems in American education from interdisciplinary, international, and systems perspectives. The book has several aims: to build a new model of achievement gap research and policy; to provide evidence on the state and alterability of achievement gaps; to synthesize separate lines of domestic and international achievement gap research; and to evaluate and inform American P-16 (pre-school through college) education policies.In light of socioeconomic changes and educational paradigm shifts, Jaekyung Lee extends the scope of analysis from a K-12 to a P-16 education pipeline and from domestic racial/social groups to international groups, with focus on the case of South Korea. Through multilevel and longitudinal analyses of U.S. national and international datasets, The Anatomy of Achievement Gaps provides new evidence on the status and trends of achievement gaps, causes of these gaps, and the effects of policy interventions. In an effort to evaluate the nation’s strengths and weaknesses across the P-16 education pipeline, it draws upon a wide range of educational data sources and indicators. Featuring cross-cultural perspectives beyond the U.S., Lee reframes achievement gap and educational accountability issues.
