This book is in favor of the inclusion of co-authoring in writing instruction and provides theoretical and research background to support the value of this strategy, which involves more than just peer editing and small-group revision. According to the book, co-authoring builds naturally on the social emphasis of the writing process and collaborative learning, both current practice in English classrooms. The book offers insights into successful collaborative writing interactions and provides practical suggestions on establishing groups, familiarizing students with the co-authoring process, and handling dissent and difference positively. To help teachers put co-authoring strategies into practice in their classrooms, the book also contains reproducible handouts of sample assignments and evaluation forms. (NKA)
