A perspectiva etnomatemática nos fazeres cotidianos de um feirante

Abstract

The present work aimed to understand the mathematical knowledge inspired by the life of a poorly educated marketer, through the Ethnomathematics Program. From the Ethnomathematics approach, it was possible to understand the mathematical knowledge that this vendor used in his daily work. As for the methodological course, this research was characterized as an exploratory descriptive research of a qualitative nature, aiming to answer the following research question: how did the fairground, poorly educated and without knowing how to read, assimilate and deal with mathematics in his professional daily life? Data collection was carried out through a semi-structured interview, with the market vendor as a research subject, so that, in this, it was prioritized to understand how an individual who did not have access to school, assimilated and used mathematical knowledge in his professional daily life. . As for the theoretical foundation, this work was supported by Ubiratan D’Ambrosio. The results achieved allowed us to understand the perspectives of Ethnomathematics, by demonstrating how and where the mathematical knowledge of the interviewed vendor emerged. It is understood that the mathematical knowledge acquired by the marketer can be considered an example of the Ethnomathematics Program, which was outlined through cultural experiences and the need to survive in the midst of society.
