AI-based writing feedback in ESP: Leveraging ChatGPT for writing business cover letters among Korean university students

This study explores the use of ChatGPT as a feedback tool for English cover letter writing among Korean university students in Business English courses. Fifty-one students participated in writing activities where they received feedback from ChatGPT 3.5. Survey and interview data indicate that while students were generally satisfied with the feedback process, its impact on developing higher-order cognitive skills, such as critical thinking and self-directed learning, was limited. Benefits identified include enhanced language refinement, personalized learning, and increased efficiency, but challenges such as lack of originality and potential over-reliance on AI were noted. These findings suggest that while ChatGPT can provide valuable feedback in the writing process, careful implementation is necessary to maximize educational benefits and promote autonomous learning. Future research should address these challenges and investigate the long-term effects of AI-assisted feedback on students’ writing development.
