This study investigates how AI feedback learning activities in English writing classes affect university students’ English achievement and writing motivation. It examines both cognitive and affective outcomes in EFL contexts using generative AI tools such as ChatGPT. A total of 244 first-year university students completed four writing tasks incorporating AI feedback during the revision process. Pre- and post-tests were conducted along with the Oxford Placement Test (Syndicate, 2001) and a modified version of Payne’s (2012) Academic Writing Motivation Questionnaire. Quantitative analyses revealed significant improvement in English achievement and three motivational subcomponents—enjoyment, recognition, and effort—while instrumentality showed no significant change. Qualitative analysis of open-ended questionnaire responses indicated that students valued AI feedback for error detection, coherence, and self-directed learning, yet recognized limitations such as unnatural expressions, misinterpretations, and overreliance on AI. The findings highlight the importance of AI literacy and propose a hybrid feedback model integrating AI and teacher guidance to enhance learner autonomy and writing competence.

The purpose of this paper is to investigate the effects of students’ peer feedback in collaborative English writing of general English classes. For this reason, online pre-and post-surveys were conducted on 33 students enrolled in D University in Chuncheongnam-do. The study results showed that in terms of the affective aspects of peer feedback, the burden of providing feedback, anxiety about English proficiency and negative feedback, and discomfort with negative feedback decreased. At the same time, the perceived usefulness of peer feedback increased. However, cooperation and responsibility, trust in peer feedback, motivation, and the burden of interaction did not show statistically significant differences. In addition, students mentioned that they benefited from peer feedback in the order of grammar, text structure, and vocabulary. As positive aspects, they highlighted objectivity, assistance in English learning, and increased confidence. On the other hand, they pointed out their discomfort in giving feedback due to their low English proficiency and the possibility of providing incorrect information. Based on the results, several implications are discussed.
