Undergraduate students rated online lecture quality, suggesting exposure influences preferences.
We examined undergraduate students' quality ratings of and preferences for different types of online lecture formats. Students preferred richer online lecture formats that included both audio and visual components; however, there were no significant differences between students' ratings of PowerPoint lectures with audio of the instructor and PowerPoint lectures with video of the instructor. Notably, students rated the quality of online lecture format higher if they had been previously or concurrently exposed to it. Thus, we suggest that mere exposure may account for much of the difference in preferences for online lectures, rather than any inherent differences in quality.
