Specialized Longitudinal Mixture IRT Model Measuring Differential Learning Progress in Target Domains

• In Event: Longitudinal and Multilevel Models

Abstract

We propose a specialized longitudinal mixture item response model that simultaneously assesses growth in a construct of interest and differential learning progress on target domains. Two empirical examples and a simulation study will be presented to demonstrate the usefulness of the proposed model over existing models.
