均衡评分政策及其对女性STEM课程兴趣的影响

中文摘要

我们表明，STEM课程中更严格的评分政策会降低STEM课程的选课率，尤其是对女性而言。我们估计了一个学生课程需求模型，以及在教授评分政策给定条件下学生最优努力选择的模型。评分政策被视为均衡对象，部分取决于学生的课程需求。STEM课程与非STEM课程之间的需求差异，在很大程度上解释了为何STEM课程给出的成绩较低。对评分政策施加限制、使各课程平均成绩趋于相等，可以缩小STEM领域的性别差距，并提高STEM课程的总体选课率。

Abstract

We show that stricter grading policies in STEM courses reduce STEM enrollment, especially for women. We estimate a model of student demand for courses and optimal effort choices given professor grading policies. Grading policies are treated as equilibrium objects that in part depend on student demand for courses. Differences in demand for STEM and non‐STEM courses explain much of why STEM classes give lower grades. Restrictions on grading policies that equalize average grades across classes reduce the STEM gender gap and increase overall enrollment in STEM classes.
