Interpretable AI in Education: A Comparison of Glass-Box Models for Predicting Student Success
Year: 2025
Type: conference-paper
Abstract: This Master’s thesis addresses early identification of first-year Computer Science students at risk of underperformance by comparing inherently interpretable (“glass-box”) predictive models with the existing Naïve Bayes–based PreSS tool. The PreSS dataset was originally compiled by Quille & Bergin from 692 first-year CS1 students across eleven institutions in Ireland and Denmark, who completed surveys on programming and mathematics backgrounds, gaming habits and a short programming test four to six hours into the course. Seventeen normalized features capturing demographic, academic and behavioural factors were extracted. In this thesis, four machine learning models are evaluated: Naïve Bayes, explainable boosting machines, automatic piecewise linear regression, and decision trees. Model performance is assessed with particular emphasis on recall to minimise the number of undetected at-risk students. Four types of explainable AI outputs (local feature importance, similar and contrastive cases, decision paths, and similar and contrastive cases) are used in a parallel survey among computer-science educators in Ireland and the Netherlands to explore educators’ confidence in model outputs.
