Interteaching: Discussion group size and course performance

Jacob C. Truelove, Bryan K. Saville, Ryan Van Patten


Researchers have yet to examine whether discussion group size affects student performance in an interteaching-based course. In the current study, we addressed this question by manipulating discussion group size (smaller groups of 2 students vs. larger groups of 4 students) across 2 sections of an undergraduate psychology course. We found no significant differences between the sections on 6 unit exams, on a cumulative final exam, and in the total number of points earned across the semester.
