The Promises and Pitfalls of LLMs as Feedback Providers: A Study of Prompt Engineering and the Quality of AI-Driven Feedback

Open access
Jacobsen, Lucas Jasper, Weber, Kira Elena·2023

Abstract

Artificial intelligence (AI) in higher education (HE) is reshaping teaching and learning, and feedback provided by large language models (LLMs) seems to have an impact on student learning. However, few empirical studies have compared the quality of LLM feedback with the feedback quality of real persons. Therefore, this study addresses the following questions: What prompts are needed to ensure high-quality LLM feedback in HE? How does feedback from novices, experts, and LLMs differ in terms of quality and content accuracy? We developed a learning goal with three errors and a theory-based manual to evaluate prompt quality. Specifically, three prompts of varying quality were created and used to generate feedback from ChatGPT-4. We provided the highest-quality prompt to novices and experts. Our results showed that only the best prompt produced consistently high-quality feedback. Additionally, LLM and expert feedback were significantly better than novice feedback, with LLM feedback being both faster and better than expert feedback in the categories of explanation, questions, and specificity. This suggests that LLM feedback can be a high-quality and efficient alternative to expert feedback. However, we postulate that prompt quality is crucial, highlighting the need for prompting guidelines and human expertise.

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.
