What does a real class run by AI agents look like? This workshop will share our experience, development process, and efficacy findings of the "AI Avatar for Every Teacher Programme" in the Faculty of Medicine at the Chinese University of Hong Kong. We have reimagined classroom interactions in medical education by giving AI avatars a physical presence as 2-meter-tall interactive touchscreens. Unlike typical mobile-based chatbots with screen-centric learning, this initiative provides our AI teachers with a highly human-like feel, guiding students through adaptive branched learning pathways based on their preparation and choices. By leveraging generative AI for voice, animation, and custom LLM integration, while grounding learning tasks in human design, the program encourages discussion and divergent thinking. Recognized with significant funding and awards, this innovation tackles student-teacher ratio challenges, enhances learning experiences, and reduces teaching burdens. Workshop participants will learn the key steps in integrating AI into their own higher education settings, allowing you to use some or all of the systems and components from our fully AI classroom.
