Book excerpt: Through the application of self-determination theory (SDT) to research and practice, this book deepens our understanding of how autonomous language learning can be supported and understood within environments outside of the classroom. Theoretical, empirical and practice-focused chapters examine autonomy support in a range of contexts and settings, dealing with learning environments and open spaces, communities and relationships, and advising and self-access language learning. They reveal what occurs beyond the classroom, how socializing agents support autonomous motivation and wellness, and how SDT can enhance our understanding of supporting language learner autonomy. It will be of interest to language teachers, university lecturers and learning advisors who are providing support outside the classroom, as well as to graduate students and researchers who are working in the fields of applied linguistics and TESOL.
