Many people are familiar with the saying “anything worth doing is worth doing well.” Writing and composition teachers could argue the same could be said of handling errors in students’ writing. In the second edition of Treatment of Error in Second Language Student Writing (2011), Dana R. Ferris provides a valuable handbook for teachers of second language (L2) writers on how to effectively treat errors in L2 student compositions and develop their accuracy and independence as writers. Throughout the book, Ferris delivers a clear and evidence-based argument that providing corrective feedback united with instruction and self-editing strategies improves student writing. Her case first unfolds from an accessible and current review of the literature and then evolves through practical, research-based tips for teachers to appropriately and successfully offer meaningful feedback to L2 writers.
