Research Biography

Dr. Li’s research interests include the development and application of experimental and quasi-experimental methods to issues in education and policy studies. Currently, his methodological work focuses on statistical power analysis for longitudinal experimental designs and multilevel randomized cost-effectiveness trials. His substantive work encompasses research on class size effects, teacher effects, school effectiveness and school improvement, effectiveness of online learning and teaching, and effects of interim assessment on student achievement.
