CALL and language learning have become complex and are accelerated with the arrival of Generative Artificial Intelligence (GenAI) tools. Bringing together experienced researchers and teacher educators from a range of contexts, this book addresses critical aspects of CALL and explores its evolution and intersection with emerging technologies. Whether a novice teacher, postgraduate student, researcher or teacher educator, this book provides inspiration and sound pedagogical examples on CALL integration. The book traces the history of CALL from its earliest behavioural iterations through to contemporary GenAI applications and covers technologies such as MOOCs, Augmented Realities and Digital Games Based Language Learning. Challenges such as technological access, pedagogical design maturity, and teacher training are critically addressed, alongside emerging intersections with GenAI. The intersection of language learning, (inter)cultural competence, and technology, and teacher education and CALL evaluation are also examined. Drawing on the concept of Festina lente , from the Latin meaning "make haste slowly", this book advocates for the idea of balancing speed with caution, highlighting that the fastest route to success often involves thoughtful action.
