Evaluates enhanced diagnostics in mathematics assessments using cognitive models and hierarchies.

Key Points

The research explores how using cognitive models and hierarchical structures in diagnostic classification models improves student assessment accuracy.
Analyzed data from 5,336 third-grade students on a standardized mathematics exam.
Constructed items based on Q-matrices derived from cognitive models.
Utilized multiple diagnostic classification models, including hierarchical extensions.
The hierarchical A-CDM model classified students into 60 latent classes with high accuracy.
This model provided more interpretable results compared to the G-DINA model.
Diagnostic outcomes improved with cognitive model-based item generation and hierarchical Q-matrices.
