Though historically perceived as an ethnically homogenous country, rapid demographic changes in the Republic of Korea have resulted in increasing diversity. However, current multicultural education programs struggle to promote acceptance and appreciation of this diversity. This paper details one pedagogical activity, a racial discrimination simulation activity designed to allow learners to experience discrimination to critically reflect on more subtle forms of oppression in society and classroom contexts. The activity was implemented in a graduate school teacher education program in Korea with 55 learners over a 4-year period. Pre-participation surveys, classroom discussions, blog postings, and reflections were analyzed using grounded theory to investigate learner reactions. Learners reported a strong disconnect between race and Korea and classrooms in Korea. Based on findings, immediate attention is necessary in teacher education programs to prepare teachers to talk about race and diversity in classrooms and confront racism in current educational contexts.
