This study examines whether exposure to mathematics content differentially contributes to mathematics achievement in fifth grade depending on the racial composition of the students in the classroom. The study found that as exposure to more diverse content increases, the racial mathematics achievement gap in the classroom narrows, suggesting that increasing opportunities to learn broad mathematics content for students in racially diverse classrooms may be beneficial.
