Microsoft Research recently released the research system StudentSim to try to solve a key problem in the development of AI tutoring tools: how to determine whether an explanation, hint, or question actually helps students progress without large-scale human experiments. Traditional AI mentors often only look at “whether the answers are correct,” but the effectiveness of teaching also depends on whether students understand, can correct mistakes, and whether different students need different answer support. Real learner research can answer these questions, but it is time-consuming, expensive, and difficult to scale, and difficult to support rapid iteration of models. To this end, Microsoft launched the StudentSim system to train each student a personalized “AI student simulator” based on public and de-identified learner records. It not only simulates how students respond independently, but also how their reactions change after receiving an explanation from their mentor.
