Holograma de celular: aplicações e contribuições para o ensino de geometria espacial

Abstract

The contents of Spatial Geometry administered in the classroom, involve spaces and three-dimensional shapes, in which comparisons, classifications and analysis are made. Thus, leaving the student with the great challenge of understanding these concepts only with theoretical classes and abstract approaches, without interaction between teacher and student. This work aimed to propose the use of the cell phone hologram methodological resource for teaching Spatial Geometry and to evaluate its effectiveness in teaching the discipline. Making objects of holographs a didactic resource during classes, it is possible to facilitate the visualization of three-dimensional figures. And with basic materials it is possible to have a hologram, being an accessible and inexpensive object for the consumer, not restricted to laboratory environments. The research is characterized as evaluative, which aimed to verify the effectiveness of using the cell phone hologram as a technological resource for learning Mathematics. Twelve high school mathematics teachers participated in the research. A questionnaire was applied to teachers, through the “Google Forms” platform, in order to analyze their conception about the implementation of the technological resource in the teaching-learning process. Therefore, throughout the research it was found that when the educator adopts resources to complement his teaching method, he will be contributing to the formation of the student, stimulating creativity and the ability to learn Mathematics
