Since the 1990’s, the online peer review has held the growing amount of attentions and has turned into a research focus for global educational experts and language professionals. However, there are very limited studies worked on the part of online peer review. In this paper, we stressed on the effectiveness of online peer review on improving EFL writing among Chinese undergraduates. Two groups are picked as the experimental group and the control group respectively, the conclusion was made on the basis of carefully collected data and qualitative- quantitative methods. The results proved that the online peer review contributed to the effectiveness for college students’ writing performance. Admittedly, our research has deficiencies in both width and depth of processing and analysis. More efforts are expected to carried on the afterward exploration.
