The effects of incentives, instructor motivation and feedback strategies on faculty evaluation response rates in large and small class sizes

Abstract

Four instructor-led strategies designed to increase faculty teaching response rates were assessed across both small (n < 50) and large (n ≥ 50) class sizes. The interventions included: (a) individual incentives, (b) group incentives, (c) instructor motivation and (d) instructor motivation plus feedback. A comparison group utilizing the standard university strategies was also included in the study. The percentage of answers to open-ended or qualitative questions was measured across groups. The results show that implementing a contingency – whether group or individual – significantly improves the rate at which students complete course evaluation ratings regardless of class size; however, these contingencies, while effective for increasing overall rating response rate, do not promote increased submission rates of qualitative comments. Furthermore, it was found that class GPA did not differ across intervention strategy nor did it influence response rates.
