The research program of Marian Hickendorff focuses on mathematics education in primary schools. Her ambition is to give empirical basis to questions and discussions about mathematics education, such as: What is the effect of presenting a mathematics problem as a story problem? How do children solve math problems like 812–784 and to what extent are children with different math achievement levels inclined to use a ‘clever’ shortcut strategy? What is the performance level of Dutch children at the end of primary school: What goes well and where is room for improvement? Furthermore, Marian aims to encourage the application of modern statistical techniques in research into learning and cognition. The focal techniques are latent variable models such as item response theory (IRT) and latent class and latent transition analysis (LCA/LTA).
