Using data from interviews, student work, and classroom observations in a “History of Race” course at a private predominantly White high school, this article examines the racialized tensions that led the teacher (first author) to create an unofficial affinity group for students of color that met outside of class. The authors argue that the teacher's attempt to implement a curriculum that was culturally affirming for students of color by de-centering Whiteness led to White students’ resistance that necessitated the creation of (...) an unofficial “safe space” outside of the classroom for the students of color. The need for such a group demonstrates the difficulties inherent in presenting a more honest account of the role of race and racism in the United States that challenges narratives of historical progress. The article concludes that while students of color ideally should have access to culturally affirming knowledge inside social studies classrooms, this experience demonstrates why that kind of knowledge can only be engaged effectively within learning spaces that challenge the norms of conventional social studies education.
