Cover Story: This study analyzes machine learning methods used to examine how engineering students make decisions during a design challenge based on a CAD simulation. We illustrate the effectiveness of supervised and unsupervised models like XGBoost, SVM, and Random Forest in pinpointing specific topics in students’ design choices by using an argumentation framework to support their informed trade-off decision-making. This study looks at how combining qualitative and computational methods can improve the accuracy and precision of topic modeling alongside human validation, showing the effectiveness of XGBoost in predicting topic distributions. As a result, our study addresses the challenges of evaluating student performance, offering more efficient and reliable ways for these evaluations through technology-driven open-ended assessments in engineering education.
