O desenvolvimento do aplicativo RA.Geo: contribuições da realidade aumentada para o ensino de geometria espacial

Abstract

This research deals with the development of a didactic resource based on Augmented Reality technology for the teaching of spatial geometry. By allowing three-dimensional virtual objects to overlap an image of the real world, in order to complement it and make possible the extraction of new information, this was the technology chosen to propose a solution to the difficulties encountered in learning spatial geometry related to the lack of development of the visualization ability and the exclusive use of the classroom math textbook, as it may not be the most appropriate tool for working on content that addresses the three dimensions. In order to develop an application software for mobile devices to be used in conjunction with the math textbook, the INTERA methodology of learning object development was adopted to support each stage of its construction, from its planning to its validation . In order to be evaluated by students and teachers, the developed application software, called RA.Geo, was applied in a high school mathematics class at a state school in the city of Jataí - Goiás. The analysis of the data produced during this application showed that the Augmented Reality, used in mobile devices and used as didactic resource, can bring benefits to the learning of spatial geometry.
