Catherine Lewis
Director
Catherine Lewis, Ph.D., comes from three generations of public school teachers. She has conducted research in Japanese and U.S. schools for more than three decades, publishing the first English-language accounts of Japanese lesson study. A research scientist at Mills College, Lewis has developed video and print materials that have introduced many educators to lesson study. She has directed seven multi-year research projects funded by U.S. federal agencies, and her randomized, controlled trial of lesson study with mathematical content resources (Rebecca Perry, Co-PI) was identified by a What Works Clearinghouse criteria review as one of only two studies of mathematics professional learning (of 643 reviewed) to meet scientific criteria and positively impact students’ mathematical proficiency
