Book excerpt: Recent developments in education, such as the increasing linguistic diversity in school populations and the digital revolution which has led to new ways of being, learning and socialising, have brought about fresh challenges and opportunities. In response, this book shows how technology enriches multilingual language learning, as well as how multilingual practices enrich computer assisted language learning (CALL) by bringing together two, thus far distinct, fields of research: CALL and multilingual approaches to language learning. The collection includes contributions from researchers and practitioners from three continents to illustrate how native languages, previously studied languages, heritage languages or dialects are activated through technology in formal and informal learning situations. The studies in this book showcase multilingual language use in chat rooms, computer games, digital stories, ebook apps, online texts and telecollaboration/virtual exchange via interactive whiteboards. This volume will be of interest to researchers interested in language learning and teaching and to practitioners looking for support in seizing the opportunities presented by the multilingual, digital classroom.
