Abstract

DYNAMIC GEOMETRY: GEOGEBRA SOFTWARE AS ASSISTANT TOOL IN THE STUDY OF THE PROPERTIES OF REGULAR POLYGONS Bruno Galdino dos Santos1 Glageane da Silva Souza2 SUMMARY The present work approaches the use of dynamic mathematics software in the classroom. class and its main objective is to study how the use of GeoGebra software influences the study of the properties of regular polygons. In order for us to reach our goal, we used as a source of research the application of a didactic sequence in a class of the 3rd year of high school at a private school in the city of Cuité-PB, which took place on May 8 2023. The application took place on the UFCG campus, in the computer lab of the degree in Mathematics. The application was attended by 11 students, 6 boys and 5 girls and lasted approximately 1 hour. We made qualitative, quantitative approaches and interpretative to analyze the aspects involved in the research. The collected data were obtained through observations made during the didactic sequence and through the students' responses to a questionnaire delivered at the end of the application. Based on data analysis, we realized that the how we use GeoGebra interfered in a positive way in the students, however, in different ways. Among the studied properties we have, inscription and circumscription of regular polygons and calculation of the sums of angles of regular polygons. In conclusion, we note that, within the adequate conditions and with a well-executed planning, the use of software in the process of teaching-learning of mathematics, specifically geometry, proved to be quite relevant, providing better interaction between student and teacher. Furthermore, we have seen that GeoGebra contributed effectively to the understanding of the content taught in the didactic sequence, awakening in some students curiosity, motivating them to explore the software beyond what was planned. Of this Thus, we conclude that the use of GeoGebra and similar software is effective in the process of teaching-learning of mathematics, highlighted, GeoGebra in the aid of the study of properties of regular polygons.
