Here a Game, There a Game: classification, gamification, and retrieval learning

A multi-user classification system is used in a classroom setting. Groups of students take samples, then collaborate on conducting experiments and building classification trees. Students are motivated by a point scoring system as they build the trees: formative gamification. Once the trees are completed they are exchanged between groups. The trees are constructed with structural commonality enabling them to act as content for template-based identification games: summative gamification.
