Researchers have developed a novel AI tutor system designed to assist non-native English speaker students in computing courses. This system processes questions in languages like Mandarin and provides bilingual responses, along with generating glossaries of technical terms. Utilizing a specialized Retrieval-Augmented Generation (RAG) pipeline, the AI tutor successfully answered 83.52% of evaluated Piazza posts correctly and helpfully. The system also demonstrated strong performance in providing translations and generating technical term glossaries, highlighting the potential of multi-source RAG for supporting students facing language barriers. AI
IMPACT Enhances accessibility of technical education for non-native English speakers, potentially increasing global participation in computing fields.
