This document discusses how educators can design games for learning. It begins by defining what makes something a game, noting they usually have goals, rules, feedback, and voluntary participation. It then discusses four categories of games and learning: games in education, repurposing non-educational games, gameful learning which takes inspiration from good games, and game-based learning which designs games for specific learning goals. The document emphasizes how games keep people engaged through constant feedback, challenges at an appropriate level, collaboration, and flow. It suggests educators can apply these principles when creating their own educational simulations.
