Modelagem matemática no processo de ensino-aprendizagem de geometria no ensino médio

Abstract

This work presents a research linked to the Graduate Program in Education for Science and Mathematics of the Federal Institute of Education, Science and Technology of Goiás, Jataí Campus. The research motivations arise around the question: How to approach the contents of Geometry through Mathematical Modeling in a way that allows students to have a more meaningful learning? Thus, we sought to know, through the theoretical framework, the need for Meaningful Learning; the characteristics of Mathematical Modeling; the importance of geometric contents in the formation of the individual and the latest academic productions (thesis and dissertations), in view of the application of Mathematical Modeling in the teaching of Geometry. The objective of the research was to carry out a pedagogical intervention, entirely in a remote model, through Mathematical Modeling on Geometry contents, in order to make students' learning more meaningful. In this context, descriptive analyzes of the application of a didactic sequence in a remote model were carried out, working the modeling with the motivating case/problem of a municipal lake, with 3rd year high school students from a public school in the city of Mineiros, countryside of Goiás. Mainly concepts of area and volume of irregular elements, geometric shapes and spatial notions were addressed. The entire investigative process took place in the form of emergency remote classes due to the social distancing necessary in the period of the new Coronavirus pandemic. The research results pointed out new ways of application of Mathematical Modeling around the geometry content, gleaming signs of a significant learning of the participating subjects.
