GeoGebra como herramienta didáctica en la enseñanza de áreas y perímetros de figuras planas en el séptimo grado

Abstract

This study analyzes the impact of GeoGebra to improve the teaching of areas and perimeters of plane figures, in students in the seventh year of General Basic Education at the Francisco Moscoso School of Basic Education, for the 2022-2023 school year. A proposal for didactic sequences was developed with the support of GeoGebra to facilitate the understanding of areas and perimeters of plane figures. The research methodology adopts a mixed approach; We work with two groups, control and experimental, where the variables academic performance and motivation of the students regarding the proposal are evaluated. The technique for analyzing academic performance is a test of knowledge about areas and perimeters of plane figures. To compare the results, the z test is used, which is used to compare the mean scores between the groups. The statistical results indicate that the intervened group, which received the proposal with the support of GeoGebra, obtained better results in academic performance, thus demonstrating the effectiveness of the educational proposal. In addition, motivation is measured through a survey with closed and open questions, where the answers reveal an increase in motivation to learn mathematics. This study contributes to the field of educational mathematics by highlighting the effectiveness of GeoGebra in teaching geometry.
