Análise etnomatemática para atividades de pedreiros: uma proposta de adequação do ensino de matemática para o Novo Ensino Médio

Abstract

The course of the Brazilian education is being discussed and a package of changes is proposed to build the one that has been called the New High School. It is presented here a proposal of action aligned to the new demands of this modality. To do this, the previous recognition of this new territory is made, gathering information on how to act with the new rules of the game. In the face of a curriculum that values empirical knowledge and an array that enables the development of elective disciplines, even with themes that receive little or no space within the classrooms, an elective is created whose chosen menu It deals with an old acquaintance: Ethnomathematics. From the choice of civil construction as the research strand, emerges a search for the mathematical essence of the bricklayer. Its mathematical practices and knowledge are analyzed from a scientific standpoint in order to disseminate such ethnomathematics. This arsenal of techniques is taken to the analysis within the school, relating the strategies adopted by these professionals with the theoretical knowledge accumulated in the classrooms. The main objective is to present to students some aspects of the relationship "formal mathematics × Informal mathematics", valuing both and promoting empathy for this unjustly depreciated group.
