A common pitfall of gamification is to rely too much on extrinsic motivation and incentives. Extrinsic motivation refers to the external factors that influence your students' behavior, such as points, badges, leaderboards, prizes, or rewards. Extrinsic incentives can be effective in attracting and retaining your students' attention and interest, but they can also have some negative consequences. For example, they can undermine your students' intrinsic motivation, which is the internal drive that comes from their curiosity, interest, or enjoyment of learning. They can also create competition, comparison, or cheating among your students, which can harm their collaboration, cooperation, or trust. They can also distract your students from the actual learning content or goals, which can reduce their learning outcomes or transferability. You need to avoid or reduce the over-reliance on extrinsic motivation and incentives by focusing more on intrinsic motivation and incentives, such as autonomy, mastery, purpose, or feedback.
