About Me


I am a full professor at the University of Twente and also hold an endowed chair in data-based decision making at the University of Groningen. I am interested in how teachers can be supported in optimising the quality of their lessons and their impact on student learning by providing them with feedback: feedback about the features of their teaching activities (e.g. based on student perceptions, or lesson observations), and feedback about their impact on student achievement. As this kind of feedback can be the starting point of improvement-oriented activities, my research also focuses on how teachers can be trained effectively for differentiating their teaching activities in line with students’ varying instructional needs.

Other Contributions


UT Research Information System


During the last ten years I in cooperation with colleagues have conducted various projects on Data-based decision making (DBDM). In total about 150 school teams were trained for one or two years for DBDM and in the meantime we studied the impact on teaching quality and student achievement.

At the moment  I am involved in the MATCH project (https://www.matchproject.nl) in which a cognitive task analysis is conducted of instructional differentiation as a complex teaching skill based on the 4C/ID model. Based on the results a training trajectory for teachers is designed, implemented and evaluated.

I am participating in a EU-funded project called ’Promoting Formative Assessment: from theory to practice’ (FORMAS) in which in four European countries an intervention to promote formative assessment is implemented and evaluated by means of randomized controlled trials (2018-2020).
