A fourth way that technology can enhance game-based learning is by providing systems for giving and receiving feedback. Feedback is an essential component of game-based learning, as it can help learners improve their skills and knowledge, as well as motivate them and enhance their engagement. Technology can enable various types of feedback in game-based learning, such as intrinsic, extrinsic, immediate, delayed, positive, negative, verbal, non-verbal, human, and artificial. For example, technology can enable intrinsic feedback through game mechanics, such as points, levels, and rewards, extrinsic feedback through external sources, such as peers, mentors, and experts, immediate feedback through real-time responses, such as sounds and animations, delayed feedback through post-game reports, such as scores and graphs, positive feedback through praise and encouragement, such as compliments and emojis, negative feedback through criticism and correction, such as errors and hints, verbal feedback through words and sentences, such as text and voice, non-verbal feedback through gestures and expressions, such as icons and faces, human feedback through social interactions, such as chat and video, and artificial feedback through automated systems, such as bots and AI.
