This study proves there is tangible room for improvement on the bias problem with student evaluations of teachers. Changing the language of the evaluations themselves can help mitigate this issue, though of course, this is only a piece of the puzzle.
This article explores anecdotal evidence from the diverse instructors who suffer from the biased, discriminatory nature of student evaluations of teaching.
This study demonstrates that the amount of uncontrollable bias in student evaluations of teaching are so extreme that more effective instructors will obtain lower student evaluations than less effective instructors due to discriminatory bias from students. Student evaluations of teaching actually do not primarily measure teaching effectiveness, but are much more demonstrative of student perceptions of instructor identity.
While not nearly the entire equation when it comes to bias in student evaluations of teaching, gender bias plays a significant role. This article examines students at a French university who evaluate their teachers. The results showed male students have a clear bias in favor of male professors, and that all students, regardless of gender, give more favorable reviews to male professors.
