This book explores the implications of technology-mediated project-based language learning for CALL teacher development, focusing on the role of video-based instruction in elucidating challenges and opportunities to promote learner creativity in the language classroom. The volume builds on existing literature on project-based language learning by extending the focus on the affordances of machinima, digital video created by teachers and learners to capture experience in 3D immersive games or virtual worlds. Drawing on data from a large-scale research project featuring case studies that examine different facets of CALL teacher education, the book calls attention to language learning and teaching strategies that encourage both learners and teachers to develop innovative approaches in the language classroom and how such approaches promote the integration of lifelong learning skills alongside traditional linguistic competencies. Offering a dynamic contribution to the growing literature on the interface of language learning and teaching and technology, this book will appeal to students and researchers in applied linguistics and language and education, as well as those interested in the latest developments in CALL.
