Avaliando o conhecimento de geometria dos alunos do 9° ano de escolas públicas de São Gonçalo do Piauí

Abstract

Geometry is present in our daily lives in the most diverse forms, and for this reason its teaching is fundamental. For this reason, considering the importance of teaching Geometry, it was decided to carry out this study aimed at teaching Geometry in the final years of elementary school. This article aims to evaluate the knowledge of geometry (space and form) of the students at the end of the 9th grade, of the elementary school of public schools, of the schools Sebastião Cruz School Unit and Valued Ribeiro School Unit, of São Gonçalo do Piauí. It is a research of quantitative nature, for which data collection was applied a test of knowledge, with 15 questions of multiple choice, addressing the main themes of geometry (space and form), in which we separate by skills, being they analysis of two-dimensional figures dimensional properties, properties of triangles, data measurement, area perimeter and polygonal figures, figure recognition built by homotetic transformation, polygon properties, Cartesian coordinates, and basic relationships of the right triangle. It was evaluated that the students present a certain deficit in the knowledge of the areas covered in the test, since only in skill 1 (H1) they had a good development in the area of twodimensional and three-dimensional figures. In relation to the other skills, the presented results were less than 50%, which is worrying, considering that geometry is a fundamental issue for all. Thus, in view of the aforementioned facts, we can conclude that it is necessary to review the teaching program and teaching methodologies, so that there is success in the teaching and learning process of public school students
