LLM feedback for academic writing: Effects on students’ performance and engagement
Open accessAbstract
Writing and revising academic texts is a demanding task that benefits significantly from feedback provided by teachers or peers. However, providing elaborated formative feedback on students’ academic writing is time-intensive and therefore hard to implement in educational practice. As a supplementary resource, large language models (LLMs) offer the potential to support the writing process by generating automated feedback to help students enhance their texts. The present study examined the accuracy of LLM-generated feedback on student texts and its effectiveness in improving university students’ revision performance and engagement in academic writing. In a randomized controlled experiment, a sample of N = 144 university students wrote an abstract summarizing a research article. All participants were then instructed to revise their abstracts; half received individualized feedback generated by GPT-4 using a standardized prompting procedure. Controlling for the quality of the initial drafts, regression analyses revealed that LLM-generated feedback led to higher revision quality and increased behavioral engagement, as measured by revision time and edit distance. Furthermore, behavioral engagement partially mediated the effect of feedback on revision quality. These findings demonstrate that LLMs can provide high-accuracy, effective feedback on academic writing. The study discusses the potential applications and implications of this technology within higher education contexts.

The quality of LLM-generated writing feedback is not always reliable.
“While LLMs can provide immediate and detailed feedback on writing across grammar, clarity, organization, content, and argumentation (Liang et al., 2024;Dai et al., 2024;Glüsing et al., 2026), the quality of such feedback is not always reliable.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
