De Bock, Dirk; Neyens, Deborah; Van Dooren, Wim – International Journal of Science and Mathematics Education, 2017
Recent research on the phenomenon of improper proportional reasoning focused on students' understanding of elementary functions and their external representations. So far, the role of basic function properties in students' concept images of functions remained unclear. We add to this research line by investigating how accurate students are in…

De Bock, Dirk; Van Dooren, Wim; Verschaffel, Lieven – International Journal of Science and Mathematics Education, 2015
We investigated students' understanding of proportional, inverse proportional, and affine functions and the way this understanding is affected by various external representations. In a first study, we focus on students' ability to model textual descriptions of situations with different kinds of representations of proportional, inverse…

Lem, Stephanie; Kempen, Goya; Ceulemans, Eva; Onghena, Patrick; Verschaffel, Lieven; Van Dooren, Wim – International Journal of Science and Mathematics Education, 2015
Box plots are frequently misinterpreted and educational attempts to correct these misinterpretations have not been successful. In this study, we used two instructional techniques that seemed powerful to change the misinterpretation of the area of the box in box plots, both separately and in combination, leading to three experimental conditions,…

Ebersbach, Mirjam; Van Dooren, Wim; Verschaffel, Lieven – International Journal of Science and Mathematics Education, 2011
The present study aimed at investigating children's and adolescents' understanding of constant and accelerated motions. The main objectives were (1) to investigate whether different task formats would affect the performance and (2) to track developmental changes in this domain. Five to 16 year olds (N = 157) predicted the distances of a moving…

Chen, Limin; Van Dooren, Wim; Chen, Qi; Verschaffel, Lieven – International Journal of Science and Mathematics Education, 2011
In the present study, which is a part of a research project about realistic word problem solving and problem posing in Chinese elementary schools, a problem solving and a problem posing test were administered to 128 pre-service and in-service elementary school teachers from Tianjin City in China, wherein the teachers were asked to solve 3…
