Now in its second edition, this volume provides an up to date, accessible, yet authoritative introduction to feedback on second language writing for upper undergraduate and postgraduate students, teachers and researchers in TESOL, applied linguistics, composition studies and English for academic purposes (EAP). Chapters written by leading experts emphasise the potential that feedback has for helping to create a supportive teaching environment, for conveying and modelling ideas about good writing, for developing the ways students talk about writing, and for mediating the relationship between students\’ wider cultural and social worlds and their growing familiarity with new literacy practices. In addition to updated chapters from the first edition, this edition includes new chapters which focus on new and developing areas of feedback research including student engagement and participation with feedback, the links between SLA and feedback research, automated computer feedback and the use by students of internet resources and social media as feedback resources.
