Peer Feedback Comments and Revision Strategies of L2 Writers: Insights from the Analyses of Teir Refection Texts Yukako Hatakeyama 1. Introduction and Literature Review Writing in academic contexts is a complex and demanding activity. Indeed, it requires various skills and knowledge: content knowledge, rhetorical understanding, genre awareness, control of linguistic and extralinguistic features, and strategies for managing the writing tasks, to name a few (Ferris, 2018a). This is already a challenge for those writing in their frst language (L1). Yet second language (L2) writers face additional challenges since they are still in the middle of second language acquisition. Abstract This paper aims to investigate what types of feedback comments pre-intermediate to intermediate learners of English in a women’s university in Japan generate in peer review. It also intends to clarify how the learners revise their essays. The participants consisted of two groups: One did peer review fve times, and the other re- ceived automated writing evaluation (AWE) feedback four times before one peer-review occasion. The partic- ipants’ refection texts were used as data for analyses. The fndings suggest that second language (L2) learners provide more critical feedback than compliments and more comments on global aspects of essays than local points in both groups. Time-series analyses and comparison with a control group that received AWE feedback showed that the number of peer-review opportunities contributed to increased critical comments and the com- ments on global points. It was also found that more specifc and writer-friendly feedback comments consisting of two or three steps increased as the participants became more experienced in peer review. In both groups, the rate of the writers’ incorporation of critical comments into their revisions was found to be high, and they also used their own ideas and judgments to revise their drafts. Implications of the fndings and limitations of this research are discussed.
