The Effect of Teacher Gender on Student Achievement in Primary School
基于随机实验数据，发现女教师会降低贫困社区女生的数学成绩，但对男生成绩或女生阅读成绩无影响，且该负面效应仅持续于数学背景有限的女教师所教女生。
Using data from a randomized experiment, we find that having a female teacher lowers the math test scores of female primary school students in disadvantaged neighborhoods. Moreover, we do not find any effect of having a female teacher on male students' test scores (math or reading) or female students' reading test scores, which seems to rule out explanations pertaining to the unobserved quality differences between male and female teachers. Finally, this negative effect seems to persist only for female students who were assigned to a female teacher with a limited math background.
