Bio

Catherine Lewis has pioneered use of Lesson Study (jugyou kenkyuu) in US schools. Lesson Study is a collaborative, practice-based form of professional learning that allows Japanese educators to continuously improve their instruction. With funding from the US Department of Education and NSF, she has developed and tested a series of resource kits to support lesson study in the US, including key resources translated from the Japanese elementary mathematics curriculum. Her randomized controlled trial of lesson study with mathematical content resources was identified by a What Works Clearinghouse-criteria review as one of only two professional learning programs (of 643 reviewed) to meet scientific criteria and positively impact students’ mathematical proficiency.  Lewis has served as an advisor to lesson study projects in the US and abroad, and has hosted national and international conferences that have attracted capacity groups of educators for public research lessons in California schools.
