AI Teaching Assistant That Switches Roles for Students and Teachers

A new study from Greek researchers introduces an AI assistant designed for secondary education — but it's not your average chatbot. The system uses three different AI models working together: Gemini, DeepSeek, and a smaller model called Gemma. What makes it special is its dual persona: it can act as a patient tutor for students, breaking down tricky concepts like budgeting or healthy eating, or it can switch to being a teaching assistant for educators, helping them design quizzes and classroom activities.

To do this, the AI relies on a technique called RAG (letting the AI look up specific information from approved sources). The researchers fed it official Greek textbooks, segmented into structured units, so its answers stay aligned with what students are actually supposed to learn. The pilot subject is home economics, which covers money management, health, and social responsibility — topics that benefit from clear, practical examples.

The AI is smart about context. When a student asks about saving money, it responds simply and encouragingly. When a teacher asks how to teach that same topic, it gives lesson structure and assessment ideas. That role-switching is the real innovation. It means one tool can serve both sides of the classroom, saving teachers prep time and giving students a study buddy available any hour.

Of course, it's early days. The study is a framework and pilot, not a full classroom rollout. But the idea of an AI that understands its audience — not just the words, but the person asking — could reshape how educational technology is built. No more one-size-fits-all chatbots.
