AI-GENERATED FEEDBACK VS. TEACHER FEEDBACK: WHICH IMPROVES WRITING ACCURACY MORE?

Abstract

This study investigates the comparative effectiveness of AI-generated feedback and teacher-provided feedback on improving students’ writing accuracy. A quasi-experimental design was employed with two groups of English language learners: one receiving feedback from an AI-based writing assistant and the other receiving feedback from experienced teachers. Writing accuracy was measured through pre- and post-tests, focusing on grammatical correctness, lexical precision, and coherence. Results indicate that both feedback types significantly improved accuracy; however, teacher feedback led to greater improvements in coherence and idea development, while AI-generated feedback produced more immediate gains in grammar and mechanical correctness. The findings suggest that integrating AI tools with traditional teacher feedback may offer a balanced approach to enhancing writing accuracy. Implications for pedagogy and future research directions are discussed.
