Introduction: Group concept mapping may be used as a learning strategy that can potentially foster collaborative learning and assist instructors to assess the development of knowledge organization in medical students. Methods: Group concept maps were created by 39 medical students rotating through a fourth year medicine rotation. The group maps were developed based on a clinical vignette. Descriptive statistics and thematic analysis of students’ evaluations were performed. Results: Evaluations indicated that students enjoyed the collaborative nature of the exercise and the knowledge sharing activities associated with it. Group maps can demonstrate different knowledge organization Discussion: Group concept mapping can be used to explore students’ organization and integration of knowledge structures in a collaborative setting. Additional research should focus on how group mapping and learning progresses over time and, whether group mapping can help identify curricular strengths and needs.
