Cognitive Diagnostic Modelling for Mathematical Modelling Assessment

2020
In a professional development workshop, we measured mathematical modelling as a performance assessment representing a multidimensional construct where dimensions are established with the performance indicators provided in a rubric. The study showed that a multidimensional non-compensatory psychometric model for scoring mathematical modelling ...

Explanatory Cognitive Diagnostic Models

2019
Student- and school-level information from large-scale educational data have been shown to explain trends in test taker performance and to inform factors that can enhance the learning environment. This study presents methods to specify and model predictive relationships of latent and observed explanatory variables within a cognitive diagnostic model ...

Information matrix estimation procedures for cognitive diagnostic models

British Journal of Mathematical and Statistical Psychology, 2018
Two new methods to estimate the asymptotic covariance matrix for marginal maximum likelihood estimation of cognitive diagnosis models ( CDM s), the inverse of the observed information matrix and the sandwich‐type estimator, are introduced. Unlike several previous covariance matrix estimators,
