Modelling while problem posing -A case study of preservice teachers

International audienceBecause problem posing might enhance activities that are necessary for solving real-world problems, it has the potential to foster modelling. However, systematic research on the connection between problem posing and modelling is largely missing. Therefore, in the present study, we investigated (1) the modelling activities that take place when posing problems that are based on given real-world situations and (2) the extent to which modelling activities occur with different problem-posing activities. To address these questions, we asked seven preservice teachers to first pose a problem based on a given real-world situation and then to solve their self-generated problem. A qualitative content analysis revealed that modelling activities that are close to the real-world situation (e.g., understanding, simplifying, and structuring the given pieces of information) are involved in problem posing. This result indicates that problem posing has the potential to foster mathematical modelling
