O ensino de lógica na sala de aula de matemática: uma proposta

Abstract

This research is part of the Mathematics Education area and proposes the inclusion of the study of Logic in mathematics classes. It aimed to investigate the production of a set of tasks on concepts of Logic, formulated for the insertion and study of this content in the mathematics classroom of the ninth grade of elementary school. This work is characterized as a qualitative research approach, developed with field research, with two participating students from a class of ninth grade of elementary school in the public school system in the city of Juiz de Fora, Minas Gerais. The theoretical framework adopted in this research was the Model of the Semantic Fields, proposed by Romulo Campos Lins (1999, 2012), from which it was possible to analyze the speeches of students through their production of meanings on the proposed tasks. The analysis of the speeches and records of the students is evidence of the potential of introducing Logic in the mathematics classroom, through tasks that stimulate logical thinking. The educational product resulting from this research consists of a teaching proposal for mathematics teachers in the ninth grade of elementary school and / or high school consisting of a set of tasks addressing concepts of logic and themes related to it.
