Uma investigação sobre o ensino de porcentagem no 6º ano do ensino fundamental

Abstract

The study purpose was to develop set of tasks, guided by theoretical assumptions, about percentage that had as main objective to stimulate the production of meanings of students when they have to do some activities to solve tasks on percentage. The survey was of a qualitative nature and developed with two pairs of students in the elementary school sixth grade in Santana do Deserto-MG. The research presented the following issues: how to develop a set of tasks that involved the topic percentage, for use in classrooms of the sixth grade of elementary school, that stimulated the production of meanings of the students and what the production of meanings of the students to the tasks proposed. Some of our results showed that students used rules to solve the problems proposed. Then, in any data absence in the utterance that could preclude the use of these rules, the student researched presented difficulties in finding another resolution strategy that was not the use of the same. The theoretical framework used in the reading analysis of the production of meanings of the students was the model of Semantic Fields. The set of tasks consisted in an educational product for use of mathematician teachers in elementary school classroom.
