From: In-lecture quizzes improve online learning for university and community college students
Error bars are 95% confidence intervals. Participants in the control condition did not have any onscreen distractors (N = 235). Participants in the medium distractor condition had three memes on the right side of the screen during the lecture (N = 235). Participants in the strong distractor condition had three TikTok videos playing on the right side of the screen throughout the lecture (N = 233). Each dot represents the data of an individual participant. The dots were displaced horizontally to improve visibility.
