A UTILIZAÇÃO DO APLICATIVO SÓLIDOS RA NO ENSINO DE GEOMETRIA ESPACIAL, UM ESTUDO COM ALUNOS DO 3º ANO DO ENSINO MÉDIO

Abstract

The overall objective of this article is to analyze the contributions of the Sólidos RA app to the teaching and learning of spatial geometry by 11th-grade students at the Federal Institute of Piauí, Floriano Campus. The research is based on the understanding that the teaching of mathematics—especially spatial geometry—still faces challenges related to the abstract nature of the content, the difficulty of three-dimensional visualization, and the persistence of traditional methodologies. To address these challenges, a teaching sequence was developed using the Sólidos RA app, an augmented reality-based tool that allows students to visualize, manipulate, and explore geometric solids in a three-dimensional environment. The study employed both qualitative and quantitative approaches and was designed as a case study. The data collection instruments used were a pretest, a posttest, a semistructured questionnaire, and participant observation. The results demonstrated significant improvement in student performance, with the average score rising from 2.13 on the pretest to 4.48 on the posttest. Furthermore, observation revealed greater student participation, interest, and engagement during the workshop. It is concluded that the Sólidos RA app contributed to making learning more visual, interactive, collaborative, and meaningful.
