Written Corrective Feedback for L2 Development [PDF ebook] 

Written corrective feedback (CF) is a written response to a linguistic error that has been made in the writing of a text by a second language (L2) learner. This book aims to further our understanding of whether or not written CF has the potential to facilitate L2 development over time. Chapters draw on cognitive and sociocultural theoretical perspectives and review empirical research to determine whether or not, and the extent to which, written CF has been found to assist L2 development. Cognitive processing conditions are considered in the examination of its effectiveness, as well as context-related and individual learner factors or variables that have been hypothesised and shown to facilitate or impede the effectiveness of written CF for L2 development.
