A Matemática de Concreto: o trabalho com ângulos na construção civil com vistas a uma intervenção didática na Educação Básica

Abstract

The present research in the area of Mathematic Education intended to understand how the relation between the schooled knowledge and knowledge produced in civil construction happens. Aiming to identify possible approximations/distances between mathematic uses in a classroom and in a construction site, a data collection was realized in two contexts: interviewing civil construction workers and interviewing and monitoring activities of a undergraduate math students' classroom. The informations provided by this two groups were treated under the light of ethnomathematics, main theoretical source of this research. Produced in a program of post graduation that aims to act in the development and qualification of Basic Education teachers, this work brings as a main result the presentation of "the other's math" and the possible articulations between different ethnomathematics. It is expected that this research become subside to a reflection between limits and potentialities of inserting the practices of the construction sites as pedagogical support of teaching math, specially of geometry, such in Basic Education as also in the formation of mathematic teachers.
