This book focuses on the reciprocal benefits and challenges that arise from effective collaboration between the various actors in language education. Drawn from eight countries on three continents, the twelve chapters report on research carried out in a wide variety of educational contexts. For all their diversity of purpose, theme and focus, all chapters emphasize collaboration and reciprocity as central components of educational research, and they make a significant contribution to a debate that is of increasing importance to researchers, teachers, teacher educators, policymakers and funding agencies.
