Interpreting Learning Under Competing Models: Joint and Stepwise Approaches for Dynamic Cognitive Diagnosis
arXiv:2606.06804v1 Announce Type: new Abstract: Digital learning environments record learners' responses to individual items, making it possible to study the development of specific skills rather than overall scores. Drawing conclusions about learning from these data requires a model that links responses to latent skills and tracks how mastery changes over time. When the skills measured by each item are unknown, the analyst must decide whether to estimate this structure, the Q-matrix, jointly with the learning process, or to establish it first and study learning afterwards. We show that this d
The proliferation of digital learning environments is generating vast amounts of granular learner data, enabling more sophisticated analysis of skill acquisition and development.
Improving the accuracy and interpretability of learning models is crucial for personalized education, workforce training, and the development of more effective AI-driven learning systems.
This research explores methods to better understand the underlying skill structures and learning processes within digital education, potentially leading to more targeted and efficient pedagogical interventions.
