 However, similar to the economic literature other researchers outside of educational psychology have offered negative findings on course evaluations.For example, some papers have examined online course evaluations and found them to be heavily influenced by the instructor’s attractiveness and willingness to give high grades in return for very little work.Another criticism of these assessment instruments is that largely the data they produce are difficult to interpret for purposes of self- or course-improvement, given the number of variables that can affect evaluation scores.
