Luz, câmera, animação : uma reflexão sobre a construção dos conceitos de geometria espacial

Abstract

In this work, it is presented a research in Science and Mathematics Teaching, which consisted in the investigation of a pedagogical practice applied to students of the 8th year of Elementary School, about the concepts of Spatial Geometry. In view of the discrepancy between the curricular grid of the Municipality, in which the students are inserted and the new National Common Curricular Base, as well as, the curiosity and the desire to do more of the researcher, the theme of this research appeared. Conceived to understand how the production of audiovisuals with the aid of manipulable materials can contribute to the appropriation of the concepts of Spatial Geometry, the project achieved its main objective that was to promote the occurrence of learning of Spatial Geometry concepts through the use of manipulable materials and the production of audiovisuals. Based on Paulo Freire’s theoretical conceptions of learning, which has autonomy as an educational principle, this project also developed solid foundations for a new educommunicational model, essentially horizontal, democratic and dialogic of the Educommunication. It was promoted the construction of communicative ecosystems, developing a dynamic and pleasant process structured through the Three Pedagogical Moments. A mediative evaluation was at the service of the students' learning and of the improvement of the pedagogical action, contemplating the self-assessment of both the students and the teacher. The data, built and tabulated through Discursive Textual Analysis, showed the progress of the students in the development of the five geometric, for the learning of Geometry to occur: Visual, Verbal, Graphic, Logic and Application abilities. In addition, autonomy was fostered that generated ideal conditions for the development of knowledge, freedom of expression, creativity, and dialogue, and what Freire calls "Think Right". As a final product, a didactic guide was developed, that can be used as learning resources by other Basic Education teachers.
