Rellensmann, Johanna; Schukajlow, Stanislaw; Leopold, Claudia – Educational Studies in Mathematics, 2017
Drawing strategies are widely used as a powerful tool for promoting students' learning and problem solving. In this article, we report the results of an inferential mediation analysis that was applied to investigate the roles that strategic knowledge about drawing and the accuracy of different types of drawings play in mathematical modelling…

Schukajlow, Stanislaw; Krug, André; Rakoczy, Katrin – Educational Studies in Mathematics, 2015
Prompting students to construct multiple solutions for modelling problems with vague conditions has been found to be an effective way to improve students' performance on interest-oriented measures. In the current study, we investigated the influence of this teaching element on students' performance. To assess the impact of prompting multiple…
