Dynamic computer modelling is a valuable way to learn about complex dynamic systems (Löhner, van Joolingen, Savelsbergh, & van Hout-Wolters, 2005; Spector, 2000). In a modelling task, students create an executable model in order to build and express their understanding of scientific phenomenona. Once the model is built, the data it produces can be compared to the expected or observed behaviour. The model can be modified depending on the outcome of this evaluation (Penner, 2001). Despite its benefits modelling is often experienced as difficult for students. For instance, students often fail at successful modelling behavior, because they do not use their prior knowledge while working on an inquiry modelling task (Sins, Savelsbergh, & Van Joolingen, 2005). Such observations highlight the need to support the modelling process. In the present paper, descriptions of drawing sketches of the modelled system as a means to support modelling are presented. Two approaches can be distinguished: drawing to prepare the model and drawing the model itself.
