RegulaTutor: A Theory-Informed Framework for Long-Term Personalized Learning

RegulaTutor is a theory-informed framework for long‑term personalized tutoring that links a learner’s historical evidence to instructional support. Guided by self‑regulated learning research, it uses a cognitive, affective, metacognitive, and motivational (CAMM) framework to derive evidence‑supported learner interpretations and teaching policies that are updated as new observations arrive. The framework includes PairRoute, an offline refinement procedure that distinguishes harness, model, and mixed failures, proposes targeted harness revisions, and constructs stage‑level supervision for confirmed model failures, improving historical‑evidence accuracy, learner diagnosis, and teaching quality across evaluated model configurations.

Universal Textual Teaching for LLMs

The paper introduces Universal Textual Teaching (UTT), a parameter‑update‑free framework that distills knowledge gaps between a Teacher and Student large language model into a reusable natural‑language artifact called a Primer. UTT identifies representative gap cases, then iteratively refines the Primer through a cycle of student attempts, prompter‑generated teaching instructions, teacher demonstrations, and synthesizer consolidation. Experiments on math (Omni‑MATH‑2) and code generation (KernelBench) show significant accuracy gains, outperforming prompt engineering and parameter‑based knowledge distillation, and the Primer generalizes across different Teacher‑Student pairs.

PEARL: Training Socratic Tutors with Pedagogically Aligned Reinforcement Learning

PEARL is a framework that trains Socratic tutoring agents using pedagogically aligned reinforcement learning. It introduces a controllable student simulator to model diverse cognitive states, a reward model that jointly evaluates pedagogical quality and correctness, and a stable multi‑objective RL approach to balance competing tutoring goals. Experiments demonstrate that PEARL competes with both open‑source tutoring systems and leading proprietary LLMs.
