Abstract Several studies highlight teachers’ challenges when posing and analysing modelling problems, often due to the absence of tools supporting these professional tasks. Thus, an important question refers to the effect of implementing different training strategies on the ability of prospective teachers to pose and assess modelling problems. Our study involves a sample of 110 pre-service primary school teachers, divided into three groups. The first group received extensive theoretical and practical teacher training in mathematical modelling based on the proposal of the study and research paths for teacher education. The second group received intensive theoretical training based on a didactic guide outlining the characteristics of modelling problems. The third group, which acts as a reference group, solely relied on the information provided by the Spanish curriculum. All participants undertake the same experience, involving the redesign and analysis of three textbook word problems into modelling problems. The results shed light on teachers’ training needs and the effectiveness of the tools in enhancing their ability to pose and assess modelling tasks at the primary school level.
