This book explores teachers' understanding of the personal and professional experiences that have informed their language teaching. The intent of the paperback edition is to bring into our professional conversations teachers' “ways of knowing” – that is, teachers' understanding of the experiences that have informed their language teaching. By making teachers' ways of knowing public, open to review, and accessible to others in this profession, this text hopes to validate, in ways afforded to other forms of scholarly work, teachers' own understanding of the activity of language teaching.
