Catherine Lewis, Senior Research Scientist at Mills College, directs instructional improvement projects funded by NSF, IES and private foundations. Fluent in Japanese, she wrote the first English-language articles about Lesson Study and has introduced many educators to Lesson Study through her writings and videos, including Lesson Study Step-By-Step: How Teacher Learning Communities Improve Instruction and Can You Lift 100 Kilograms?  The randomized controlled trial of fractions Lesson Study she conducted with Rebecca Perry significantly improved students’ fractions proficiency.
