We surveyed students (N = 152) in several sections of an undergraduate educational psychology course to determine what course factors would most motivate them to submit course evaluations. The survey directed students to choose among several pairs of course characteristics as to their relative impact on their decision to submit a course evaluation. After tabulating their choices, we ranked the course characteristics for the total sample and then for various demographic and performance subgroups. In general, students indicated that positive aspects of a course would motivate them to submit course evaluations more than would negative aspects.
