In this study, the researcher examined student conceptions of "Whiteness" as it relates to past and present U.S. history. Using Critical Race Theory as the lens, this study employed mixed methods, analyzing teacher observations, classroom artifacts/student work, survey, and interview data from White students and students of color at an ethnically and economically diverse urban high school. The results showed most students could explain that race had an important role in U.S. history and could supply examples of race playing a role in specific historical events. However, students of color were more likely to express that racism is still common in the current day, while White students were more likely to express that racism is uncommon.
