My research as a PhD-candidate for the Expertisepunt rekenen-wiskunde focuses on teaching chance, randomness and uncertainty to vmbo-students (vocational secondary school) with special attention for their mathematical attitude and problem solving skills. I have a Master's degree in Mathematics from the University of Groningen and a Master's degree in Education from the University of Utrecht. In the past I taught mathematics to secondary school students for several years and I have developed teaching materials (on paper and digital) for mathematics lessons.
