Contextualizing gender disparities in online teaching evaluations for professors.

Student evaluation of teaching (SET) is widely used to assess teaching effectiveness in higher education and can significantly influence professors' career outcomes. Although earlier evidence suggests SET may suffer from biases due to the gender of professors, there is a lack of large-scale examination to understand how and why gender disparities occur in SET. This study aims to address this gap in SET by analyzing approximately 9 million SET reviews from RateMyProfessors.
