註釋Previous research suggests that student evaluations of teacher performance are biased against women. We test this hypothesis on economics students in a randomized, double-blind experiment, set up in a natural educational setting. During the Covid-19 pandemic, teaching assistants moved online and answered questions through email instead of on-campus group sessions. We randomly assigned a male or female name to the instructions given by the online teachers. Importantly, the teachers actually responding to the questions did not know whether they interacted with the students as male or female, which is a novel contribution to the literature. The course evaluation asked students to rate the mentors' helpfulness, knowledge, and response time. The results show no bias against the female mentor in any single dimension. Our confidence interval around the zero effect does not overlap the effect sizes reported in highly influential previous studies.
