Modelagem matemática na aprendizagem de geometria plana: aplicação no cálculo de área e perímetro

Abstract

The central theme of the present research is Mathematical Modeling in the learning of Plane Geometry and it is justified by the desire of the author to help in an approach of change in the teaching of mathematics, where traditional teaching sometimes causes students to lose interest. Furthermore, the study, which is a topic aligned with the researcher’s area of expertise, will contribute to improving her practice as a future teacher. The general objective of this work is to analyze the contributions of Mathematical Modeling in the learning process of Plane Geometry. As for the methodology applied, this is a participant research project of a qualitative nature. Data was collected by reading articles, theses and dissertations, applying a diagnostic activity and a Mathematical Modeling workshop applied to Plane Geometry. The locus of the research is the Vereador Valdemar Soares de Oliveira Municipal Educational Center, in the municipality of Piripiri – PI. The theoretical framework has been divided into three categories: Learning Mathematics, Plane Geometry and Mathematical Modeling. As a result, it was found that many students have difficulty calculating the perimeter and area of flat figures, especially if the calculation of the surface requires decomposition of the figure. Furthermore, Mathematical Modeling proved to be a powerful strategy that can transform the teaching of Plane Geometry, making it more engaging and meaningful for students, since it is applied in a planned way.
