Picture your favorite college professor. Here are some adjectives that might come to mind: Wise. Funny. Caring. Prompt. Passionate. Organized. Tough but fair ( . . . ) Now, are you thinking of a man or a woman? A new study argues that student evaluations are systematically biased against women — so much so, in fact, that they're better mirrors of gender bias than of what they are supposed to be measuring: teaching quality.
Anne Boring, an economist and the lead author of the paper, was hired by her university in Paris, Sciences Po, to conduct quantitative analysis of gender bias. Through her conversations with instructors and students, she became suspicious of what she calls "double standards" applying to male and female instructors ( . . . ) (T)he team ran a series of statistical tests on two different data sets, of French and U.S. university students.
The French students were, in effect, randomly assigned to either male or female section leaders in a wide range of required courses. In this case, the study authors found, male French students rated male instructors more highly across the board. Is it bias? Or were the male instructors, maybe, actually, on average, better teachers? ( . . . ) Well, turns out that, at this university, all students across all sections of a course take the same, anonymously graded final exam, regardless of which instructor they have ( . . . ) (T)he students of male instructors on average did slightly worse on the final. Overall, there was no correlation between students rating their instructors more highly and those students actually learning more.
The American case was a little bit different. Here, the authors performed a new analysis of a clever experiment published in 2014. Students were taking a single online class with either a male or female instructor. In half the cases, the instructors agreed to dress in virtual drag: The men used the women's names and vice versa. Here, it was the female students, not the males, who rated the instructors they believed to be male more highly across the board. That's right: The same instructor, with all the same comments, all the same interactions with the class, received higher ratings if he was called Paul than if she was called Paula. And that higher rating even applied to a seemingly objective question: Did this teacher return assignments on time? (The online system made it possible to ensure that promptness was identical in every case.) ( . . .)
What to make of the fact that the bias was wielded primarily by men in France and by women in the U.S.? "That the situation is Really Complicated," Philip Stark writes in an email to NPR Ed ( . . . ) (T)he authors titled their paper "Student Evaluations of Teaching (Mostly) Do Not Measure Teaching Effectiveness."
These results seem pretty damning, but not everyone is convinced. Michael Grant is the vice provost and associate vice chancellor for undergraduate education at the University of Colorado, Boulder. He says there's a lot of research supporting the effectiveness and usefulness of student evaluations ( . . . )
