Resumo
Esta pesquisa tem como objetivo investigar como que a Linguagem Vernácula e a Linguagem Matemática contribuem no trabalho com números racionais quando se faz uso da Metodologia de Ensino-Aprendizagem-Avaliação de Matemática através da Resolução de Problemas. Esta pesquisa foi desenvolvida seguindo a Metodologia Científica de Romberg-Onuchic apresentada por Onuchic e Noguti (2014). Apresentamos a fundamentação teórica desta pesquisa a partir de três variáveis-chave (Resolução de Problemas, Linguagem Vernácula e Linguagem Matemática, Números Racionais). Procuramos investigar de que forma as Linguagens Vernácula e Matemática contribuem para o trabalho com as diferentes personalidades do número racional visando a aprendizagem e a avaliação do aluno ao se adotar a Metodologia de Resolução de Problemas. Para tanto, estabelecemos como procedimentos da pesquisa a elaboração de um Projeto e sua aplicação em uma turma de 6º ano do Ensino Fundamental de uma escola estadual da rede pública de ensino da cidade de Rio Claro - SP. Esse Projeto envolve o ensino de algumas personalidades do número racional apresentadas por Botta e Onuchic (1997) como ponto racional, fração e quociente. Percebemos que o trabalho do professor de incentivar os alunos a entenderem os significados das palavras presentes nos enunciados dos problemas que envolvem números racionais, possibilita que eles compreendam e escrevam usando da linguagem vernácula para que possam dominar a linguagem matemática corretamente.
This research aims to inquiry how the native language and the mathematical language contribute in the work with rational numbers when we carry out a practice in the Teaching - Learning - Assessment Methodology of Mathematics through Problem Solving. That study was developed with the scientific methodology of research of Romberg - Onuchic as pointed out by Onuchic and Noguti (2014). We came out our theoretical tenants in three variables - key, such that: Problem Solving, native language and mathematical language, an d rational numbers. We had looked for following up from which ways the native language and mathematical language can contribute to the educational work with the different personalities of rational numbers in the use of methodology on Problem Solving. There fore, we had pointed out as research procedures the figuring out of a project and its application at a 6 th grade of the E lementary School in a State Public School of the City of Rio Claro – SP. This project encompasses the teaching of some personalities of the rational numbers, such that: rational point, fractions and quotient presented by Botta and Onuchic (1997). Within that work, we can perceive that the mathematic’s teacher’s work with the practical methodology of Teaching - Learning - Assessment through Pr oblem Solving end up allow ing that actors of that cenary can understand and write finding out the native language to hold upon the mathematical language correctly and properly.
