The purpose of this article is to clarify some of the elements involved in an effective workspace for problems related to geometric loci in technological environments. It analyzes how 52 prospective math teachers progress in their conception of the concept of geometric locus through the appropriation of the specific features of each environment (tool) in relation to their own practice as students and their future professional activity. The mathematical representations of loci generated by three different dynamic geometry tools have been compared, both from the perspective of their mathematical dynamics and their didactic functions. The didactic functionalities provided from the designer have been studied from the Mathematical Working Space model (MWS).
