ITAS: A Multi-Agent Architecture for LLM-Based Intelligent Tutoring

arXiv:2604.24808v1 Announce Type: cross Abstract: Large language model tutors are easy to build in a notebook and hard to run in a real course. We describe ITAS (Intelligent Teaching Assistant System), a multi-agent tutoring system that a graduate quantum computing course used for a semester at Old Dominion University. The system has three layers. The teaching layer is a Spoke-and-Wheel of three parallel specialist agents (Video, Code, Guidance) followed by a Synthesizer, plus a separate autogra
