"Smith and Lewis develop in-depth the single most effective approach to professional development—mentoring. Facilitative mentoring is flexible, experiential, and relational. This book goes beyond buzzwords to specific steps and contexts, richly illustrated with real-world examples. For those committed to mentoring as effective and deeply transformative, this interactively-designed book is an invaluable and indispensable guide." -- Bradley Baurain, Moody Theological Seminary and Graduate School, USA"This important and original book, drawing on research and practice as well as vignettes that reflect practitioners’ perspectives and experiences, fills a much needed gap in the TESOL professional development literature and will be an invaluable resource for teachers and teacher educators."--Jack C. Richards, University of Sydney and University of Auckland
