Collaborative learning is a pedagogical approach that emphasizes group work and project-based learning to promote problem-solving skills and deeper understanding. However, collaborative learning also presents challenges. One common issue is social loafing, whereby people contribute less to a group effort than they would if they were working alone. In more serious cases, this leads to free-riding, where some students do little or no work but still receive credit for the group’s efforts. At the Faculty of Engineering at Lund University, group-based projects are a central part of most courses, especially in the later stages of study. This article examines strategies to minimize social loafing and prevent free riding in collaborative learning environments.
