FEAT: A Preference Feedback Dataset through a Cost-Effective Auto-Generation and Labeling Framework for English AI Tutoring
This addresses the need for scalable feedback data in AI tutoring for English education, though it is incremental as it builds on existing LLM methods.
The study tackled the problem of generating high-quality teacher feedback for AI-based English tutoring systems by proposing FEAT, a cost-effective framework that creates three datasets through human-LLM collaboration and LLM-only generation, with results showing that adding 5-10% of human-LLM data to LLM-only data yields superior performance compared to using 100% human-LLM data.
In English education tutoring, teacher feedback is essential for guiding students. Recently, AI-based tutoring systems have emerged to assist teachers; however, these systems require high-quality and large-scale teacher feedback data, which is both time-consuming and costly to generate manually. In this study, we propose FEAT, a cost-effective framework for generating teacher feedback, and have constructed three complementary datasets: (1) DIRECT-Manual (DM), where both humans and large language models (LLMs) collaboratively generate high-quality teacher feedback, albeit at a higher cost; (2) DIRECT-Generated (DG), an LLM-only generated, cost-effective dataset with lower quality;, and (3) DIRECT-Augmented (DA), primarily based on DG with a small portion of DM added to enhance quality while maintaining cost-efficiency. Experimental results showed that incorporating a small portion of DM (5-10%) into DG leads to superior performance compared to using 100% DM alone.
