Group work (GW) in undergraduate education facilitates the development of communication and collaborative skills. However, dysfunctional and inequitable group dynamics can have adverse effects, leading to increased anxiety. This research sought to determine the effectiveness of a Group Work Contract to facilitate the GW process in the face-to-face (n=168) and online (n=105) formats of a third year nutritional science course. Changes in students' attitudes and approaches to GW were assessed before (semester week 4) and after (semester week 12) completion of the contract and assignment via online surveys. The results in both course formats were similar, wherein the Group Work Contract reduced student anxiety and improved group dynamics and communication between group members, resulting in an improved learning experience overall. Further, the preferred methods of GW online communication utilized social networking platforms. This data demonstrates the benefits of formally structuring the GW process to optimize the student learning experience.
