Résumé
When teaching mathematical modelling it becomes essential to be able to construct modelling tasks of a similar difficulty for projects and exams. In order to be able to compare these tasks, an evaluation scheme concerning the difficulty becomes necessary. In this paper, we introduce an extension of a model developed by Bock, W., Bracke, M., Götz, T. & Siller, H.-S. (2014) which is based on a model from Eyerer & Krause (2012) for comparing difficulties of projects between industry and school. This is used to evaluate the difficulty of a modelling task. The theoretical model of Bock and colleagues (2014) is made applicable by means of a software tool: Taking into account all relevant dimensions of modelling, a measure of difficulty is calculated based on the normalized covered area in the constructed multi-dimensional model. This allows a comparison of the difficulty of several modelling tasks.
