A Professor Like Me: The Influence of Instructor Gender on College Achievement
利用学生随机分配教师的数据，发现教师性别对大学生成绩影响很小，但同性教师最多能提高成绩标准差的5%，并降低1.2个百分点的退课率，表明性别榜样对部分学生有作用。
Many wonder whether teacher gender plays an important role in higher education by influencing student achievement and subject interest. The data used in this paper help identify average effects from male and female college students assigned to male or female teachers. We find instructor gender plays only a minor role in determining college student achievement. Nevertheless, the small effects provide evidence that gender role models matter to some college students. A same-sex instructor increases average grade performance by at most 5 percent of its standard deviation and decreases the likelihood of dropping a class by 1.2 percentage points.
