Resolução de sistemas de equações lineares utilizando o software Winplot: uma aplicação prática com alunos do ensino médio

Abstract

This article aims to investigate if high school students can understand the resolution of 2x2 and 3x3 lineares systems from an approach that favors the conversion and representation register treatment combined with a computational environment. Find out if high school students can convert the algebraic record into graphs; to verify if the students can convert the algebraic register to the graphic register and the algebraic treatment by the scaling method and to evaluate the influence of winplot software on the learning of lineares systems. In addition, it checked whether they can perform the algebraic treatment by the scaling method and examines the influence of winplot software on learning the content in question. The research consists of the application and analysis of semi-structured questionnaires that address algebraic, graphical situations and algebraic treatment with and without the use of winplot software. However, from the 15 students subject of the research it was found that 67% of the students solved the systems and built the graph correctly, while 33% could only build the graph with the aid of the computing environment. This shows that the use of mathematical software with winplot and GeoGebra can be a strong ally in understanding mathematical content
