Drawing on the literature and research findings from relevant research fields, including educational technology, educational psychology, adult and workplace learning, and language education, this book gives an overview of the relationship of learner and teacher autonomy and technology in language teaching. It discusses how technology both benefits and constrains autonomy, and how a positive interaction between the two could be fostered. It underscores a critical perspective in understanding their relationships and a holistic approach to boosting a positive reciprocal relationship between the two.
