A Community College Instructor Like Me: Race and Ethnicity Interactions in the Classroom
利用一所大型多元化社区大学的行政数据，研究发现少数族裔学生由同族裔教师授课时，辍学率降低20%-50%，成绩差距缩小，并影响后续课程选择和学位完成。
Administrative data from a large and diverse community college are used to examine if underrepresented minority students benefit from taking courses with underrepresented minority instructors. To identify racial interactions, we estimate models that include both student and classroom fixed effects and focus on students with limited choice in courses. We find that the performance gap in terms of class dropout rates and grade performance between white and underrepresented minority students falls by 20 to 50 percent when taught by an underrepresented minority instructor. We also find these interactions affect longer-term outcomes such as subsequent course selection, retention, and degree completion.
