Findings indicate that writing is a dynamic, recursive interplay of three major processes: planning, drafting, and revising. Experiencing this writing process, L2 learners have more to write and write it well. Therefore, this article suggests incorporating literature into L2 writing process as an effective way to improve traditional writing instruction.展开更多
