Attraktivität, Reziprozität und Lehrveranstaltungsevaluation

In this article we investigate the relationship between academic teachers’ attractiveness and their students’ evaluations of teaching. Furthermore it is examined, whether teachers’ grading influences students’ evaluations of teaching. Using data from an experimental design, hypotheses about attractiveness effects, frog-pond-effects, moderating gender effects and influences of grading are empirically tested. Controlling for confounding factors we find a very weak attractiveness effect, which can partly, but not only be ascribed to beauty’s productivity enhancing influence. Thereby, independently from the raters’ sex, female teachers profit from their looks. In contrast to that attractive male teachers are even sanctioned more strongly by their students for difficult tests than unattractive teachers. The frog-pond-hypothesis cannot empirically be supported: the attractiveness of teachers’ colleagues has no influence on the attractiveness effect. However, reciprocal evaluation behavior can consistently be found in the theoretical expected manner. It is substantially more relevant for students’ evaluations of teaching than attractiveness effects are. Alternative explanations for this grading effect can be excluded.
