The integration of artificial intelligence and natural language processing (NLP) into engineering education research and practice represents a set of opportunities to expand how we understand student learning, assess educational outcomes, and scale qualitative research methods. This talk presents a comprehensive overview of methodological innovations developed in the IDEEAS Lab over the past five years to leverage the power of generative AI, large language models, and NLP techniques for advancing engineering education. I will present three interconnected methodological contributions: (1) AI-assisted qualitative analysis, where I demonstrate how generative text models can perform traditional thematic data analysis while maintaining rigor and validity; (2) AI-assisted assessment and feedback systems, showcasing applications of open-source language models for analyzing student responses, teamwork feedback, and ethics case studies; and (3) mental models research at scale, illustrating how NLP techniques can help uncover engineering faculty and student mental models of complex topics like sustainability, assessment, and now generative AI itself.
