Author: Bilir, M. K., Binici, S., & Kamata, A.

Increasing attention has been paid to Growth Mixture Modeling (GMM) in recent social and behavioral science literature. However, the use of this methodology in educational research is still in his infancy. The purpose of this article is to demonstrate an application of GMM to longitudinal educational data from large-scale reading tests.

Author: Kamata, A. Chaimongkol, S., Genc, E., & Bilir, M. K.

This study introduces a random-effect differential item functioning (DIF) model that allows one to estimate the variation of DIF across group units. A three-level hierarchical generalized linear model is adopted.
