"Treatment of Error in Second Language Student Writing "is the book many writing teachers have long been looking for: a highly accessible and principled approach to the theory and practice of error treatment that can guide pedagogical decision-making.Unlike a teachers' manual or a handbook that purports to give all the answers needed, Ferris's research-based volume offers a solid scholarly foundation for the practical ideas presented together with an abundance of illustrative sample texts. This book will be a rich resource in language teaching methodology courses, but experienced teachers too will no doubt benefit from the depth and breadth of Ferris's coverage of various error response techniques as well as of the research that motivates those techniques.Ferris offers a realistic, well-reasoned account of what second language (L2) writing teacher--or teachers with L2 students in their classes--need to know about error and how to put what they know to use. She persuasively addresses the fundamental error treatment questions that plague novice and expert writing specialists alike: What types of errors should teachers respond to? When should we respond to them? What are the most efficacious ways of responding to them? And ultimately, what role should error treatment play in the teaching of the process of writing?
