Professional Encounters in TESOL investigates the developing discourses of English Language teachers in a variety of international contexts. By analysing how professional development takes place through participation in professional discourse, the chapters shed light on what teachers do and why they do it. The book is organised in four sections, reflecting the stages in an English language teacher's career: 'Starting Out' focuses on initial teacher training, 'Becoming Experienced' looks inside their classroom, 'New Horizons' shifts the perspective to the professional development of experienced teachers, and 'Passing on Knowledge' investigates the discourses of experienced teachers as they contribute to the professional development of their peers. Each section is followed by reflections on the chapters written by a teacher from an international context at the particular stage in their professional development reflected in the section. The book should have particular appeal to all those working in the area of teacher development and will also be of interest to practising teachers.
