A importância da argumentação matemática na resolução de problemas

Abstract

Currently, a decadence of formalism in the teaching of mathematical contents is perceived, mainly in basic education where most books only address ready-made formulas, making it impossible for the student to build mathematical knowledge through deductive logic. In this sense, the present work aims to develop a proposal that develops the mathematical contents with a certain rigor and formalism, using logic to demonstrate the main formulas and theorems, all of this using reading, writing and argumentation as a potentiating ferment in the process of problem solving, aiming at improving writing in problem solving and a better understanding of mathematical content by students. The study had as scenario the Municipal Elementary School Severino Marinheiro, in the city of Juazeirinho-PB. The research subjects were 40 students from a ninth grade class who studied at the aforementioned school. At the end of this work, we will be able to perceive the importance that writing develops in the learning of students in the final years of basic education, allowing the organization of ideas and thinking in the problem solving process, a fact that allowed the awarding of some students involved in this proposal at the 17th OBMEP.
