Exploring LLMs for Predicting Tutor Strategy and Student Outcomes in Dialogues

Abstract: Tutoring dialogues have gained significant attention in recent years, given the prominence of online learning and the emerging tutoring abilities of AI agents powered by LLMs. Recent studies have shown that the strategies used by tutors can have significant effects on student outcomes, necessitating methods to predict how tutors will behave and how their actions impact students. However, few works have studied predicting tutor strategy in dialogues. Therefore, in this work we investigate the ability of modern LLMs, particularly Llama 3 and GPT-4o, to predict both future tutor moves and student outcomes in dialogues, using two math tutoring dialogue datasets. We find that even state-of-the-art LLMs struggle to predict future tutor strategy while tutor strategy is highly indicative of student outcomes, outlining a need for more powerful methods to approach this task.
