| Abstract Type: | Contributed Poster Presentation |
| Abstract: | This study examined how peer discussion affects student understanding in traditional calculus-based mechanics courses. A randomized controlled trial (RCT) was conducted with two parallel classes of approximately 40 students each, both taught by experienced instructors. During the 90-minute class, which met once a week, students alternated between small-group discussions (PD) and teacher-led blackboard explanations (BB) while working on exercise problems in a crossover structure. A post-test administered immediately after class showed no significant differences between PD and BB for most problems. For some problems, BB demonstrated a higher correct answer rate. This presentation will report on these results in detail, including the relationship between problem types and improved understanding. |
