Article Excerpt: A new Dartmouth study finds that artificial intelligence has the potential to deliver educational support that meets the individual needs of large numbers of students. The researchers are the first to report that students may put more trust in AI platforms programmed to pull answers from only curated expert sources, rather than from massive data sets of general information.
Professor Thomas Thesen and co-author Soo Hwan Park, MED ’25, tracked how 190 medical students in the Geisel School of Medicine used an AI teaching assistant called NeuroBot TA, which provides around-the-clock individualized support for students in Thesen’s Neuroscience and Neurology course.
Thesen and Park built the platform using retrieval-augmented generation, or RAG, a technique that anchors the responses of large language models to specific information sources. This results in more accurate and relevant answers by reducing “hallucinations,” AI-generated information that often sounds convincing but is inaccurate or incorrect.
