Teaching format and student style: Their interactive effects on learning

This research compared the effectiveness of Peer-Centered (PC) and Instructor-Centered (IC) formats for Teaching-Assistant-led discussion sections in chemistry. In addition, an Aptitude-Treatment Interaction (ATI) was hypothesized, such that self-described “collaborative” students would report more learning from the PC format and “competitive” students would benefit more from the IC format. The PC format utilized small subgroups and student presentations, while in the IC format the Teaching Assistant lectured, solved problems, and answered questions. The two sections were approximately equal in overall learning, except that more learning from fellow students occurred in the PC sections. The expected ATI effect was found. In addition, students with interpersonally oriented learning styles benefited more from interactive learning opportunities (such as sections), while those with other learning styles gained more from impersonal media (such as textbooks).
