O Uso do GeoGebra 3D com realidade aumentada no ensino de geometria espacial

Abstract

This research, carried out at an exploratory level, had the general objective to investigate what are the contributions of the use of the GeoGebra 3D Graphic Calculator application, with AR (Augmented Reality), for the study of geometric solids. With this objective in mind, a bibliographic research was carried out and a didactic proposal was elaborated, which was applied to the second year academics of the Mathematics degree course. The didactic proposal involved contents related to the study of prisms, pyramids and round bodies, as well as the calculation of the volume of these solids. With the activities, we sought to explore some possibilities that the application offers for the spatial geometry teaching, and to investigate if these contributed to the understanding of the contents covered, and also how was the receptivity and resourcefulness of the students regarding the use of the application. The application of the didactic proposal took place remotely, carried out in four meetings lasting two hours. Data collection took place through the sending of smartphone screenshots by the participants during the activities, and also through the application of questionnaires. When analyzing the data, it was found that the application helped students to visualize threedimensional geometric solids, making it easier for them to perceive characteristics that could go unnoticed in a two-dimensional representation. It was also found that its use allowed them to act with more autonomy in approaching the contents, exploring and interacting with the geometric constructions in AR, therefore obtaining, through their own action, numerous visual representations of the constructions, which allowed them to observe from different ways the properties applied. Thus, it was noticed that the application also contributed to the students to improve their skills in understanding three-dimensional geometric constructions. Finally, we can highlight that the use of the application provided very attractive learning moments for the students and, in a way, contributed to the activities becoming more engaging.
