What are Learner and Instructor Preferences for Group Size and Composition for a Series of Synchronous Online Case Discussions for Upper Extremity Trauma Surgeons?

Small group discussion (SGD) is a well-known educational method to promote active learning. Best practices for running SGDs in face-to-face events are described in the literature; however, little has been reported regarding synchronous online delivery. The aim of this study was to determine learner and instructor preferences for online SGDs in terms of group size and composition and to formulate best practices based on participant and faculty feedback. We designed an 8-module online course for surgeons managing upper extremity trauma. Participants were pre-assigned into 2 types of group: 1 faculty with 5 participants or 2 faculty with 8 participants. We collected feedback from 91 participants and 34 faculty over the 8 weeks in multiple ways. Participants preferred way to run an online SGD is to have 2 faculty with 4–5 participants (80%), rotating to different faculty every week (67%), and interacting with peers from different countries (95%). Pre-course assessment questions and pre-recorded presentations enhanced the online discussions for 82%. From open text comments, we identified that cases/content, faculty, participant engagement, and technical support worked well. The course could be improved by adding more extensive technical and connectivity checks, having a different time scheduling, and integrating more supporting materials.
