This entry explores the emotional and motivational dimensions of digital game-based language learning and teaching. The analysis underscores the pivotal role of play in human learning and the significance of enjoyment in language acquisition. A review of studies examining various affective and motivational aspects in language learning and teaching revealed three key findings. First, digital game-based language learning enhances intrinsic and extrinsic motivation, enriching the learning experience. This heightened motivation improves engagement and outcomes within digital learning environments. Second, digital game-based language learning positively affects learners’ enjoyment, a critical factor in sustaining engagement and interest in language learning tasks. Third, digital game-based language learning fosters collaboration and cooperation among learners, thereby enhancing teamwork skills and promoting positive attitudes through completing in-game tasks. In conclusion, future research should investigate the interplay between positive and negative emotions and the features and mechanics of educational digital games. Such exploration will elucidate the affordances of these games in enhancing the efficacy of language learning and teaching.
