This research aims to understand the role of Digital Technologies (DT) in the teaching of Calculus in distance education, in particular, in the Pre-Service Mathematics Teacher Education of the Open University of Brazil (UAB). A qualitative research approach was used, specifically the methodological approach of Grounded Theory (GT). In this approach, the researcher builds a theory grounded in concepts, categories, properties and dimensions identified through analysis of the data. The data were produced from four sources: observation in Virtual Learning Environment (VLE), interviews with teachers, tutors and students of the courses, analysis of official documents of these courses, and research field notes. Based on the produced data, it was possible to build a dialogue between poly-teaching ideas regarding the fragmentation of teaching in distance learning courses, and the theoretical construct humans-with-media, which proposes that humans and technology work together in the production of mathematical knowledge. Two roles of DT emerged as analytic categories: "DT and its role in the structuring of the course" and "DT and its role in teaching the course". In each category, three properties were developed. In the first category, they were: the course design, evaluation and online interaction. In the second category, the properties explored were: changing roles, strategy and epistemological difficulties. Later, these categories were integrated into a central category that formed the basis for defending the existence of the theoretical construct “poly-teachers-with-media”. This construct suggests that DT act in the collective of poly-teaching workers, changing roles and revealing others in this collective. Therefore, it is necessary for the VLE to be an environment rich in collaborative interactions, in which the dialogue is constantly encouraged by teachers and tutors. Once the notion of the construct poly-teachers-with-media was developed, the model was then verified in the analyzed courses, which supported the relationship with the need for collaborative interactions. With this research, it is hoped that others will begin to investigate the other roles that DT can play, not only in teaching, but also in the learning of different subjects in similar contexts.
