This article reports a research concerning a prospective teacher education experiment. The aim of this study is tounderstand the contribution of exploratory tasks to the development of spatial reasoning and which are theprocesses of spatial reasoning promoted. Data was gathered from audio and video records and the analysisfocused on the processes of constructing mental models, as well as inspecting, transforming and operating withmental models. The study suggests that the type of tasks, the physical models made available and theinteractions in the classroom are relevant conditions to the activation of these processes. In respect to the tasks,the enumeration of elements of the polyhedra and the establishment of relations and justifications promote theprocesses of spatial reasoning; the physical models are important as a support, but its use should be limited; andthe collaborative work context favours the communication of reasoning and the spatial structuring of objects.
