This chapter looks at the types, functions, and affordances of digital media for language learning. It focuses on the particular value of these media for enhancing the engagement of adolescent language learners. It discusses concepts for digital competencies (e.g. as outlined in the Common European Framework of Reference for Languages) and their connection to the everyday digital communication practices of adolescent language learners. The potential of the language classroom as a place to further develop competencies for digital communication in foreign languages is highlighted. The chapter discusses some of the recent thinking about the benefits of digital media for individualising language learning, on the one hand, and providing opportunities for social learning on the other hand, illustrated with classroom examples. Drawing on current research the chapters show how digital media, especially mobile devices, can bridge learning inside and outside the classroom and thereby provide opportunities for authentic interaction, creativity, and game-based learning. This is illustrated through examples from classrooms and the voices of students and teachers.
