Evolutionary Reinforcement Learning based AI tutor for Socratic Interdisciplinary Instruction
This research introduces ERL4SIIP, a novel Evolutionary Reinforcement Learning (ERL) framework for AI tutors designed to facilitate Socratic interdisciplinary instruction. It addresses key challenges in AI education, such as modeling dynamic student cognitive states, handling sparse rewards in long-term learning, and preventing policy collapse. ERL4SIIP integrates a dynamic student simulator, a hierarchical reward mechanism, and a LoRA-Division based optimization strategy. Experimental results demonstrate significant improvements over state-of-the-art baselines in fostering higher-order abilities like knowledge integration and interdisciplinary transfer, while also exhibiting greater teaching strategy diversity and robustness.

Problem Formulation: SIIP as a POMDP
The core challenge of Socratic Interdisciplinary Instructional Problem (SIIP) is formalized as a Partially Observable Markov Decision Process (POMDP). This accounts for the dynamic, unobservable nature of student cognitive states (knowledge, misconceptions, affective state) which traditional methods often simplify into fully observable MDPs. This precise formulation is crucial for building adaptive AI tutors that can infer and respond to latent student needs.
Dynamic Student Simulator
A key innovation is the Dynamic Student Simulator, built on a STEM knowledge graph. It explicitly models latent cognitive states including knowledge mastery, misconception activation, and affective states (frustration, engagement). This simulator acts as a high-fidelity surrogate environment for safe and extensive pedagogical exploration, circumventing the ethical and practical limitations of direct interaction with real students. It includes mechanisms for knowledge mastery updates, forgetting, misconception activation ('Shadow Graph'), and proactive student behavior.
Hierarchical Reward Mechanism
To tackle reward sparsity and hacking in long-term educational goals, ERL4SIIP introduces a Hierarchical Reward Mechanism. This system decomposes complex instructional goals into dense, non-deceptive signals across three layers: a Constraint Gatekeeper (ensuring pedagogical safety), Process Rewards (evaluating Socratic quality, interdisciplinary links, personalization), and Outcome Rewards (measuring actual student cognitive growth). This structured feedback loop is vital for training agents that promote genuine conceptual reorganization rather than superficial answers.
LoRA-Division Based Evolutionary Reinforcement Learning
The LoRA-Division Based Evolutionary Reinforcement Learning (ERL) strategy addresses the optimization challenges of LLMs for Socratic pedagogy. It decouples global exploration (via evolutionary algorithms on low-rank EA-LORA adapters) from local refinement (via PPO on low-rank RL-LORA adapters). This approach prevents 'strategy collapse' common in gradient-based RL, maintains diverse teaching personas, and makes population-based search computationally feasible for large language models.

Socratic Scaffolding vs. Spoon-feeding
A comparative case study highlights ERL4SIIP's ability to drive cognitive struggle and deep integration, contrasting with baseline methods that resort to 'spoon-feeding'. For a 'Rote Learner' student, ERL4SIIP's 'Strategic Socratic Guide' led to a self-generated 'Aha Moment' by prompting physical observation and cross-disciplinary inference, ultimately resolving misconceptions and fostering knowledge transfer. The baseline's 'Efficient Lecturer', however, provided direct answers, leading to passive acceptance and superficial integration, failing to activate higher-order thinking.
