Elementos valorizados por professores de matemática na elaboração e implementação de tarefas no contexto da álgebra

Abstract

In the present study we have investigated elements valued by Mathematics teachers, in moments of elaboration and implementation of exercises in the context of Algebra. For the development, the researcher participated in study meetings and followed the classes of participants of a group of studies in progress since 2013. Data for this research were collected in meetings held in 2017, during which time the group had the participation of five teachers who worked in public schools. The field diary, audio recordings of the group meetings, written records by the teachers involved and the students' written output from the implementation of the exercises were used as instruments for gathering information. The analysis was qualitative of an interpretative nature and had as theoretical presuppositions aspects related to the work with exercises in Mathematics classes, in articulation with assumptions for the Teaching of Algebra in the final years of Elementary School. The following elements were identified by the teachers in this process: the constitution of a suitable environment for mathematical learning; the maintenance of the level of cognitive demand of the exercises and the attribution of meanings to the algebraic operations.
