Abstract
With the recent boom in artificial intelligence (AI) , AI has been added to countless tools to aid in our lives. As educators, we are interested in the possibility of applying recent developments of Generative AI models, particularly Large Language Models (LLMs), to help engineering students with their course work.
In this project, our goal is to get an AI program to act like a good Teaching Assistant (TA), providing a useful learning aid for students who have questions outside of office hours or for students who are not comfortable in office hours. This idea can perhaps also help where the TA budget is tight. Also, it might provide assistance for working engineers who are trying to learn on their own.
After proper training, the AI program ideally should answer correctly any class-related questions from a student. In our work, we are using course material for an undergraduate electrical-engineering course on transistor circuits. We have focused on early material on diode and transistor construction and operation, but we also tested the AI TA on some text-book chapters that cover single-transistor amplifiers.
In the paper, we will describe our approach to evaluating on-the-market models for this purpose, as well as, the training and fine-tuning of models to achieve a high-performance AI TA. We will present our evaluations of an AI TA’s ability to precisely point a student to sections in the given textbook as well as its ability to give a detailed explanation to a question, as a human TA would do. Limitations of the AI TA and potential extensions of this work will also be covered.
