This study aims to investigate the effects of anonymity of peer feedback on Korean college students’ English writing revision by comparing face-to-face and anonymous feedback. Students took English writing tests and shared written peer feedback according to where the comments are given: in-text, marginal and end-note comment. The acceptance rates of face-to-face and anonymous feedback as well as students’ awareness were analyzed to achieve the purpose. The results are as follows: 1) the amount of anonymous feedback was more than that of face-to-face feedback, especially in-text comment which is mostly comprised of form-focused feedback; 2) in contrast with the amount, students used more face-to-face feedback for their revision and it can be inferred that they regard face-to-face feedback as being more reliable; 3) students responded that both face-to-face and anonymous peer feedback were beneficial to their revision.
