Realidade aumentada para ensino de geometria

Abstract

This work presents the development of an augmented reality educational application aimed at teaching geometry to 3rd-grade elementary school students. It addresses recurring difficulties in learning the subject, such as excessive abstraction and student demotivation. The rationale is based on the relevance of geometry to spatial reasoning and the scarcity of accessible tools aligned with the Brazilian National Curriculum (BNCC), especially in schools with limited technological infrastructure. The overall objective was to create an interactive and gamified resource that would allow the manipulation of geometric solids in three dimensions, promoting engagement and meaningful learning. The methodology involved gathering technical and pedagogical requirements, prototyping in Unity with AR Foundation, implementing gamified activities, and conducting technical and pedagogical tests, followed by verification and validation processes. The results showed that the application performed satisfactorily on mobile devices, with unctionalities for tracking and manipulating virtual objects, as well as activities aligned with the skills foreseen in the BNCC. The conclusion indicates that augmented reality, integrated with gamification, constitutes an effective strategy for bridging the gap between theory and practice, democratizing access to digital resources, and enhancing the teaching of geometry, while also providing a foundation for future educational projects that explore emerging technologies.
