Abstract: In this article, we investigate how visualization can be an epistemic learning tool using the didactic potential of a Dynamic Mathematics System (DMS) to revisit concepts of two-dimensional linear transformations. To do this, it focuses on some DMS functions, in particular digital books (GeoGebra Books); GeoGebra Groups and students' visual perception. The research, classified concerning the technical procedures as a case study and a qualitative approach, was carried out with five students of a postgraduate course at a private university. It was concluded that the activities performed did not reach the expected range for most participants, as they fled from the initial objective. However, for these participants, they served as a review of concepts. It was observed that the DMS helped to explore the visual perceptions about the chosen topic, especially for one of the participants. Keywords: Linear transformations; Visualization; Geogebra Book; GeoGebra Groups.
