Reflecting on Peer Feedback in Problem-Based Learning: Implementing a Group Function Tool.

Introduction Self-directed peer feedback is integral to the problem-based learning (PBL) process, but poorly scaffolded feedback processes can be inefficient and ineffective and there is little guidance on how students should structure these processes. This study aims to identify implementation considerations for a group function reflection tool and explore group feedback behaviours around the operationalization of the tool. Methods We conducted a qualitative study informed by direct content analysis using the group function reflection tool and conducted semi-structured focus groups in 2024 with 24 medical students and two tutors participating in a PBL curriculum. Students conducted peer feedback using the tool over four weeks, submitted feedback through an online form, and reflected on their experiences in focus groups. We analyzed feedback responses and transcripts in a staged approach, sensitized by three frameworks: the Human Factors Framework, the Task-Gap-Action model of feedback, and Appreciation, Coaching, and Evaluation. Results We constructed five themes: 1) appreciative feedback is often under-valued, 2) there is tension between structure and flexibility in the feedback process, 3) the interplay between written and verbal feedback, 4) the density of feedback requires careful optimization, and 5) the tool as a threat to tutors. Discussion Operationalization of the tool exposed tensions around the peer feedback process. The tool reinforced the importance of a self-guided process for peer feedback which also requires prompting. It raised assumptions about the PBL feedback process which should be further studied to better understand peer feedback in broader contexts.
