The rise of AI, especially Large Language Models, presents challenges and opportunities to integrate such technology into the classroom. AI has the potential to revolutionize education by helping teaching staff with various tasks, such as personalizing their teaching methods, but it also raises concerns, for example, about the degradation of student-teacher interactions and user privacy. This paper introduces INSIGHT, a proof of concept to combine various AI tools to assist teaching staff and students in the process of solving exercises. INSIGHT has a modular design that allows it to be integrated into various higher education courses. We analyze students’ questions to an LLM by extracting keywords, which we use to dynamically build an FAQ from students’ questions and provide new insights for the teaching staff to use for more personalized face-to-face support. Future work could build upon INSIGHT by using the collected data to provide adaptive learning and adjust content based on student progress and learning styles to offer a more interactive and inclusive learning experience.
Paper presentation, 3rd Workshop on Engineering Interactive Systems Embedding AI Technologies, Trier, Germany
LLMs have rapidly evolved into versatile “foundation models”, repurposed - despite persistent gaps in reliability - for a variety of tasks, such as legal document summarization, medical question answering, and text classification. In this paper, we propose an approach to engineer better text classification solutions for educational grading. We address this challenge with a solution that couples (i) a transformer cascade for rubric-level prediction with (ii) a transparent, traffic-light feedback interface powered by a Mixture-of-Agents LLM system. We compared our approach to a standard LLM and a single transformer architecture using the ASAG dataset. Results show that our approach increases recall for incorrect answers by more than 50% and precision on fully correct answers by 20% compared to a single transformer. Finally, we describe a prototype implementing our approach in an end-to-end, minimally intrusive solution for semi-automatic grading, which allows the teaching staff to review and revise the feedback generated by a Mixture-of-Agents LLM system based on the grade classification.
