About Me
I'm a doctoral candidate in Education in Mathematics, Science, and Technology program in UC Berkeley. I taught secondary mathematics at a public middle school and a public high school in Korea for 5.5 years before coming to UC Berkeley. As a teacher, I participated in several action research projects including lesson study in Korea. The experience both in Korea and in UC Berkeley have made me come to my current research which focuses on how mathematics teachers change their classroom practices toward developing students' mathematical reasoning while they support each other in two contexts: learning communities and classroom context.
Current ATS Projects
I'm working with a small group of scheme and participating classroom observation.
