Social software is changing the ways students and instructors share information and is increasingly used a part of a collaborative learning process. Collaborative learning improves engagement and is particularly effective when introduced as part of project-based learning (PBL) for teams. However, PBL for teams also introduces social dilemmas where less motivated students engage in social loafing, allowing more motivated students to do most of the collaborative work. This paper presents an approach to collaborative learning using an experimental learning management system (LMS) designed specifically for team-based PBL. This LMS assists instructors to counteract the negative effects of social dilemmas. The novel approach presented has undergone testing with Masters and senior cycle Undergraduates who engaged in team projects in the field of innovation management and strategic planning. Results presented in this paper from three real use cases show high student engagement high satisfaction, and low social loafing.
