O uso de Algeplan em uma turma multisseriada para o estudo de polinômios

Abstract

This work aimed to investigate the interaction between students during the study of polynomials in a multiseriate class during the teaching of Algebra, at a school in the countryside of the municipality of Caçapava do Sul, RS. The intervention promoted the study of polynomials, making use of of Algeplan, by students of the 8th and 9th years of Elementary School during Mathematics classes. For this, an activities was prepared, ranging from understanding the concept of monomials to operations of addition, multiplication and division of polynomials. During the application of the sequence of activities were observed the interactions between the students and recorded their comments, aiming to identify and analyze how the collaboration happened between them as they performed the tasks, as well as their understanding of the content. During the activities, students were more involved and enthusiastic in carrying out the study of algebraic operations. The use of manipulative material facilitated the understanding of the content of polynomials and provided a greater participation of students in the study. It was possible to identify occasions in which 8th year students explained how to solve the situations proposed for 9th grade students, who had already studied this content in the previous year. In general, the students' greatest difficulty was the interpretation of the proposed activities, since they were not accustomed to reasoning using manipulative material, which requires attention and effort to understand what is expected in the.
