Abstract
BACKGROUND: Debriefing is the essential element of simulation teaching. Peer-led structured debriefing simulations could be a suitable approach because of the peers' similarity in age and experience to the students. The purpose of this study was to compare the teaching effectiveness of peer-led debriefing versus instructor-led debriefing in high-fidelity simulation scenarios. METHODS: The study used a mixed-method approach, integrating quasi-experimental and qualitative components. A total of 88 third-year nursing students were randomly distributed into the instructor-led or peer-led group, with equal sample sizes in both cohorts. The study compared knowledge acquisition, simulation performance, student satisfaction and self-confidence in learning, and debriefing experience between the two groups. In addition, interviews were conducted with students in the peer-led group after the course. RESULTS: The scores of students' simulation performance scale were higher in the peer-led group than in the instructor-led group, and both groups made significant gains in knowledge. The peer-led group and instructor-led group demonstrated similar performance in terms of knowledge, simulated performance, reporting experience, student satisfaction, and learning confidence. The semi-structured interview results indicated that students in the peer-led group expressed approval of peer facilitators. CONCLUSIONS: Our study demonstrated that students in the peer-led group showed better performance in the simulation, and both groups demonstrated improved knowledge. Thus, with the premise of peers receiving training, the peer-led simulation teaching method can be regarded as a supplementary strategy for simulation teaching to enrich the form of simulation teaching and improve the effectiveness of simulation teaching.
