Queso is a classroom management system built for educators who want to run a gameful course. A gameful classroom uses game design principles to create a more engaging experience for students. For example, an assignment could be revised infinitely because games practice the idea of failing often. The various options that exist (Blackboard, Moodle, Canvas, Edmodo, etc.) require a lot of workarounds to implement gameful principles. The more established software vendors also have so many obfuscated features that it becomes a chore just to figure out how to implement something.
Queso is designed to be simple and easy to use. It is also an open source project to encourage other people to contribute and learn from the code.
