This document summarizes a study that examined how game mechanics and extrinsic motivation can be used in group awareness tools for collaborative learning. It describes how group awareness tools provide social, behavioral, and cognitive indicators about a group's contributions and goals. The study used the Learning Mechanics-Game Mechanics framework and Self-Determination Theory to analyze a specific group awareness tool called PyramidApp. The tool used feedback and behavioral momentum game mechanics to motivate participation. Students using the tool had higher participation rates and found the awareness features useful. The document proposes additional game mechanics like avatars, progression, and cooperation/competition that could further improve engagement.
