Abstract

This study leverages student performance data and the Funk-singular value decomposition (Funk-SVD) model to identify conceptual weaknesses in first-year calculus learning and generate targeted practice recommendations. Rather than relying on error counts or instructor judgment, the model infers individual learning gaps based on predicted success probabilities. Using data from six exams administered to 850 students, the model achieved strong predictive performance, with an F1-score of 0.794. Simulated intervention analysis revealed that the most substantial learning gains occurred among lower-achieving students. Frequently recommended items indicated persistent difficulties with volume integration, curvature, and Riemann sums. These findings underscore the potential of advanced recommendation models to support scalable, personalized learning–grounded in precise, data-informed diagnosis of conceptual weaknesses–thereby enabling more effective instructional support and promoting long-term academic continuity.
