Uma investigação sobre a produção de tarefas algébricas para o 6º ano do ensino fundamental

Abstract

This scientific work begins with the analysis of different concepts for algebra, algebraic thinking and algebraic activity. Those informations guide the decision making about the concept adopted as reference in this work, helping to verify how different concepts affect the teaching and learning processes of algebraic elements. This investigation is based on a qualitative approach and uses the Model of Semantic Fields (MSF) as the theoretical base. One objective of this research was the production of tasks with specific characteristics based on theoretical references aiming at aiding the development of the students’ algebraic thinking. The tasks we have developed have been applied to a group of students from the 6th grade of the elementary school, and the meanings they produced for these tasks were analyzed from the contributions of the MSF. The present research also targets at producing an educational product that consists of a set of tasks applied in the field work and in advisories that aids the teachers to use them in the classes.
