In the last 10-15 years, many institutions of higher education have switched from paper-and-pencil methods to online methods of administering student evaluations of teaching (SETs). One consequence has been a significant reduction in the response rates to such instruments. The current study was conducted to identify whether offering in-class time to students to complete online SETs would increase response rates. A quasi-experiment (nonequivalent group design) was conducted in which one group of tenured faculty instructed students to bring electronic devices with internet capabilities on a specified day and offered in-class time to students to complete online SETs. A communication protocol for faculty members' use was developed and implemented. A comparison group of tenured faculty who did not offer in-class time for SET completion was identified and the difference-in-differences method was used to compare the previous year's response rates for the same instructor teaching the same course across the two groups. Response rates were substantially higher when faculty provided in-class time to students to complete SETs. These results indicate that high response rates can be obtained for online SETs submitted by students in face-to-face classes if faculty communicate the importance of SETs in both their words and actions.
