"New directions for knowledge tracing models" is the title of Prof. Dr. Benjamin Paaßen talk, which is being organised by the "Zentrum of Statistik" at Bielefeld University. It will take place on Tuesday, 8 July 2025 from 12:00 Uhr - 13:00 in W9-109.    

Knowledge Tracing (KT) is the attempt to estimate student learning from observed behavior over time. This is typically performed with latent variable models (especially Hidden Markov Models) where the latent variable is student learning and the observed variable are data acquired from student behavior in e-learning systems, especially their success on exercises. The talk will introduce KT, cover the most prominent classic KT models, shortly discuss current machine learning research into KT, and propose potential new directions for KT research that is more compelling both from a modeling perspective and from the perspective of educational utility.
