Subclaims¶

q2 i? Most LLMs cover most of the seven feedback focus types, but their feedback focus type distributions diverge from the teacher distribution, with the educationally fine-tuned LearnLM achieving the lowest Jensen-Shannon Divergence (0.1344) and larger models showing some of the highest divergence. → Norah Almousa 2026

q2 · i? · design · r2

Population-level comparison of six LLMs' feedback focus type distributions against an aggregated teacher reference distribution across three university writing courses, using Jensen-Shannon Divergence. The study reports LearnLM's JSD of "0.1344" as the closest alignment, with Gemini and Qwen-70B showing some of the highest divergence.

"in the zero-shot setting, LearnLM achieves the lowest JSD (0.1344), indicating the closest alignment with the teacher distribution, followed by Llama-7B (0.1619) and Mistral-24B (0.1780). Among all models, the educationally fine-tuned LearnLM most closely approximates the teacher feedback focus type distribution"
