Interactive question-answering (QA) with tutors has shown to be an effective way for middle school math students to learn. While not all students have access to a tutor, large language models make it possible to automate portions of the tutoring process–including interactive QA to support students’ conceptual discussion of mathematical concepts. Some have questioned how LLM responses can be better aligned with a school’s curriculum. In this paper, Levonian and colleagues explore how retrieval-augmented generation (RAG) can help improve response quality by incorporating textbook information and other educational resources, while also identifying trade-offs of using RAG.
