An Adaptive Multi-Agent Architecture with Reinforcement Learning and Generative AI for Intelligent Tutoring Systems: A Moodle-Based Case Study
This paper presents ELA Tutor, a self-adaptive multi-agent architecture integrating Reinforcement Learning (RL) and Generative AI for Intelligent Tutoring Systems (ITS) within a Moodle LMS. It introduces an RL Meta-Agent that dynamically optimizes specialized agent selection based on user state and interaction patterns. Evaluated through real and simulated case studies, the system demonstrates improved efficiency, response relevance, and adaptability, proving the viability of RL-based MAS architectures in complex educational settings like higher education.

Multi-Agent Systems (MAS)
MAS are presented as a core component for managing complexity and scalability in adaptive tutoring systems, distributing functions among specialized agents (pedagogical, technical, analytical, empathetic, ethical) that cooperate. The ELA Tutor uses MAS to interpret user requests, generate contextualized responses, propose learning resources, and offer adaptive feedback, promoting pedagogical consistency and facilitating system evolution.
Reinforcement Learning (RL)
RL is integrated as a metacognitive mechanism for continuous adaptation, allowing the system to learn optimal policies through continuous interaction. The RL Meta-Agent acts as a high-level controller, observing interactions, evaluating results, and selecting strategies to maximize accumulated reward. A simplified Q-learning model combines user knowledge and emotional state to inform adaptive decisions, ensuring stability and interpretability in real educational contexts.
Generative AI (LLMs)
LLM models are incorporated to enable intelligent conversational agents capable of interpreting open-ended queries, generating contextual responses, and providing immediate feedback. The architecture emphasizes a clear separation between language generation (LLMs) and pedagogical decision-making (RL/MAS) to reduce algorithmic opacity, improve traceability, and facilitate teacher supervision, aligning with ethical AI principles.

Simulated RL Adaptive Behavior
A simulated case study evaluated the RL Meta-Agent's adaptive behavior. It demonstrated how the system progressively adjusts agent selection and tutorial strategies based on accumulated experience and reward signals. Positive feedback reinforced effective strategies (e.g., technical agent for procedural queries, Moodle agent for administrative queries), while negative feedback penalized inadequate ones (e.g., pedagogical agent for practical contexts), leading to policy adjustments. The system avoided unsafe exploration, falling back to heuristics when confidence was low, and showed stable convergence.
- Policy Convergence: Positive rewards for social and administrative interactions led to immediate Q-Score convergence (1.00), demonstrating robust routing.
- Adaptive Correction: Negative feedback for conceptual queries triggered penalization, leading to a negative Q-Score (-1.00) for the pedagogical agent, signaling its unsuitability for practical contexts.
- Hybrid Decision-Making: The system successfully balances learned RL policies with deterministic heuristics, ensuring safety and stability in dynamic environments.
- Scalable Adaptation: The Meta-Agent's ability to generalize learned decisions across similar interaction states proves its potential for scalable adaptation beyond static rules.
