This edited book has been compiled in honor of Thomas S.C.Farrell, one of the most distinguished scholars in theorizing and researching language teacher reflection.It examines teacher reflection in three main areas: policies, practices and the impact of teacher reflection on teachers’ practices and professional development.The data-driven chapters shed light on concerns and challenges experienced by teachers in diverse international contexts and institutions, and discuss the practical implications of their findings across a variety of policy settings.The book addresses aspects of reflective practice including macro and micro policies and constraints, as well as opportunities in the engagement of reflective practice.In addition, it explores teachers’ identity, cognition, emotion and motivation, areas which are relevant but often not discussed in the literature on reflective practice.
