Rijkje Dekker is Senior Researcher of Mathematics Education at the Research Institute of Child Development and Education of the University of Amsterdam.
"My main research area is collaborative learning of mathematics. My focus is on the relation between interaction and mathematical level raising. Together with Marianne Elshout-Mohr I developed a Process Model for Interaction and Mathematical Level Raising to study this relation. In this study I collaborate with PhD students and colleagues from different countries. For an overview of our findings in relation to learning materials, composition of the small groups and the role of the teacher, I refer to my lectures at the NWD (in Dutch) and at the ICME (in English). More detailed information can be found in my publications."
From October 2012 till April 2013 Rijkje Dekker was Professor of Mathematics Education at the University of Cologne (DE), on invitation.
Together with Monique Volman and Jannet van Drie, she was nominated for the Supervisors Prize 2014 by the PhD Division (VPO) of the Netherlands Educational Research Association (VOR).
