This book highlights the ways in which insights from technology-mediated project-based language learning research can contribute to our understanding of both learner interaction in specific cultural contexts but also of the role of technology in language learning more generally. The volume situates the discussion within the context of the development of the field, from task-based to project-based language learning, and how these have been shaped over time by the evolution of new technologies. Using the case study of EFL learners in a Japanese classroom, the book adopts a multimodal approach to unpack this phenomena at work by examining learner collaboration in project-based work in a real-world setting. The volume provides a valuable contribution to the ongoing debate about the effective integration of digital technologies in the classroom and will be of particular interest to students and scholars in applied linguistics, computer-assisted language learning, task-based language teaching, and TESOL.
