As current computer-mediated communication (CMC) research is omnipresent in the foreign/second language (L2) writing process, a synthesis of the research in this realm is needed to better understand and inform the current pedagogical practices with technology in language classrooms. This article presents a review of 38 studies identifying the major characteristics of CMC use in L2 writing process and aspects of L2 writing where CMC is embedded. The findings indicate that a variety of CMC-embedded L2 writing tasks were mainly integrated in the drafting and revising/editing stages of writing. Also, there has been a clear shift in recent years from blogs and wikis to other CMC tools, such as Google Docs, Facebook, Skype, and instant messaging. Also, existing CMC research on the L2 writing process mainly focuses on improvement in L2 writing ability/production, complexity/accuracy/fluency (CAF) measures, interactivity in L2 writing, and learners' editing/revision strategies. Finally, this review discusses pedagogical implications and offers suggestions for future research on CMC and L2 writing.
