Research

My research interests are both substantive and psychometric. Substantively, I study mathematics education in primary schools. In particular, I am interested in the type of solution strategies that students use on complex arithmetic problems such as 304 : 19 = ? - which can be for instance that they solve this problem with a written algorithm (‘staartdeling’ in Dutch) or solve this problem in their head - and how their strategy use relates to their achievement. Psychometrically, I am interested in application of different types of latent variable models to analyze this kind of data sets with strategy use and performance. In particular, my interest is in item response theory (IRT) and latent class analysis (LCA). As corollaries of my research interests, I have been working as an associate researcher supporting the KNAW Committee on Primary School Mathematics Teaching in 2009. See rapport 'Rekenonderwijs op de basisschool'.
October 2011, I defended my PhD thesis entitled Explanatory latent variable modeling of mathematical ability in primary school. Crossing the border between psychometrics and psychology. This research project involved collaboration between Leiden University and CITO, the National Institute for Educational Measurement. In my current position as Assistant Professor in Educational Studies, I am extending this research with new empirical studies on primary school mathematics.
