How does a university rate the quality of a professor? In K-12 education, you have standardized tests, and those scores have never been more widely used in evaluating the value added by a teacher.
But there’s no equivalent at the college level. College administrators tend to rely on student evaluations. If students say a professor is doing a good job, perhaps that’s enough.
Or maybe not. A new study reaches the opposite conclusion: professors who rate highly among students tend to teach students less. Professors who teach students more tend to get bad ratings from their students — who, presumably, would just as soon get high grades for minimal effort.
The study finds that professor rank, experience and stature are far more predictive of how much their students will learn. But those professors generally get bad ratings from students, who are effectively punishing their professors for attempting to push them toward deeper learning.
The study is called “Does Professor Quality Matter? Evidence from Random Assignment of Students to Professors.” It was written by Scott E. Carrell of the University of California, Davis and National Bureau of Economic Research; and James E. West of the U.S. Air Force Academy
