This book looks at aspects of L2 research that influence error correction, finding that second language acquisition takes time and that second language writers' texts differ from those written by native English speakers. Using this research, Dana R. Ferris dispels the myth that diligent teacher correction and student editing can lead to perfect, error-free texts. In clear and simple terms, Ferris makes six suggestions for things teachers can do in the classroom regarding error correction and provides samples. Other issues regarding the expectations of students and others—such as in timed (high-stakes) situations—as it relates to "perfect" papers are examined. The book closes by addressing the basic principles of developing students' language skills in second language/ESL writing classes.
