This book is the first substantive scholarly book on project-based and cross-curricular language learning using digital technologies. The book includes new empirical research on project-based language learning utilizing CALL technologies and conceptual and theoretical chapters that address new methodological approaches for researching project-based and cross-curricular language learning in digitally-mediated learning environments. This dual focus distinguishes the volume from previous books on project-based learning in which digital technologies have not been the main focus. CALL research involving a variety of languages is also offered. The book is timely in that, inspired by OECD reports and curriculum reforms in several countries, a repositioning and re-evaluation of foreign language education in school-based education has been taking place in which foreign language learning is taught in a multi-disciplinary approach involving an emphasis on collaborative literacies, including problem-solving, civic engagement, social justice and telecollaboration. In this mix, language learning, particularly driven by developments in CLIL (content and integrated language learning), is being taught as one of several disciplines in a way that firmly emphasizes communication and creativity rather than a traditional functional approach.
