The Persistence of Gender Bias in Student Evaluations of Teaching: The Role of Gender Stereotypes

Student evaluations of teaching (SET) are typically highly biased. In this paper, three experiments are reported, examining gender bias in SET by manipulating lecturer gender and counterstereotypes. Each experiment involved a vignette about a lecture, with a different context: Study 1 - noisy students disrupting the lesson; Study 2 - students asking for consideration; Study 3 - neutral context of a routine lecture. Structural equation modeling (SEM) revealed that the effect of lecturer gender on SET depended on the context and was both directly (Study 1) and indirectly (Studies 2 and 3) mediated by gender stereotypes. The effect of student's gender was indirect and mediated by gender stereotypes in all studies. Counterstereotypical descriptions did not affect stereotypical perceptions in any of the experiments. The findings are discussed in terms of social dominance theory (SDT) and social role theory (SRT). They offer novel insights into the mechanism that explains gender and context bias in SET. In terms of practical implications, SET should be considered with caution, particularly when used for critical decisions such as tenure status. Finally, applying additional assessments and statistical methods to control for gender bias is important.
