SUMMARY:

In our daily lives there are a variety of forms, especially those that have three dimensions. However, many Mathematics classes are still focused on identifying and naming plane figures and the use of static figures. Thus, the need arises to reflect on the role of Geometry in the Mathematics curriculum. The present study aims to reflect on the role of visualization in the development of geometric thinking and analyze the contributions and difficulties related to this process in Spatial Geometry activities, using paper and pencil and GeoGebra in its smartphone version. The fieldwork took place during the second half of 2019, within the scope of the Mathematics Teaching II subject, with fourteen Mathematics Undergraduates from the Federal Rural University of Rio de Janeiro as research subjects. Data was produced through written records of students from activity sheets and conceptual development production, audio recordings, captures and screen recordings of their smartphones using the GeoGebra application. We initially identified that the subjects showed difficulties in visualizing and representing the cube sections, in addition to presenting some impasses to justify their processes of solving the activities. Visualization, as an important skill of mathematical thinking, is an individual process that is not innate and therefore needs to be taught. In this way, we believe that the use of varied didactic resources in the classroom brings different contributions to stimulate and enrich the visual thinking of each subject. However, it is important to emphasize that the improvement of the subjects' visualization is not guaranteed only with the use of resources. It is necessary to invest in activities that aim to stimulate visualization and the process of justifying the answer, as visualizing, representing, obtaining the correct answer, and justifying it do not always go together in learning.
