ABSTRACT

The purpose of this paper is to verify the validity of peer feedback in university writing and to suggest the content of feedback pre-education based on empirical analysis. The effectiveness of peer feedback in the rewriting process has already been verified in several studies. However, there are concerns that feedback from low-level group does not help improve recipients' writing, but rather may lead to errors. Therefore, in order for learners to perform peer feedback successfully, the reliability of the feedback content must be increased, and for this, the instructor must increase the validity of the feedback content through pre-education. In this paper, we first looked at the criteria for validity of feedback types, and then analyzed peer feedback data produced in writing classes of G University for one semester using text mining. First, we measured the correlation of key words in feedback, compared the vocabulary usage patterns of the upper/lower groups. Next, a tone analysis method was applied to score the types of feedback by related vocabulary lists to verify the validity of the types of feedback. Based on this result, an appropriate composition of feedback types for pre-education was proposed, and the detailed expressions were also listed. While previous studies on peer feedback evaluated the validity based on the instructor's intuition, this paper is differentiated in that it tried to verify the validity through empirical analysis and propose more specific contents derived from our results for feedback pre-education.
