This study compared end-of-semester student ratings from students who provided mid-semester feedback with those who did not, to measure how consistently students rated teaching effectiveness. Participants included 394 undergraduates in seven classes. Within each class, participants randomly formed the primed group, completing an online survey twice mid-semester, or the non-primed group, completing an alternate activity at the same times. Both groups completed the university's end-of-semester survey. The results in six classes did not show any significant differences between primed and non-primed students on the final survey; however, one class revealed that non-primed students actually responded more consistently than primed students.
