Etnomodelagem: uma abordagem de conceitos geométricos no cemitério de Arraias – TO

Abstract

The need to think about new methodologies for teaching Mathematics, especially from subjects related to students’ daily life, motivated the accomplishment of this work, through the Ethnomodelling, which aims to identify mathematical ethnomodels present in the construction of the wall of the Cemetery and its square of the city of Arraias -TO providing the knowledge of part of the local reality. Considering that the knowledge acquired by cultural groups transferred from generation to generation can be important tools for students’ learning, we have prepared a proposal of Ethnomodelling that allows to observe some ethnomodels and to use them as didactic resources. This research was developed on a bibliographic basis on the theoretical basis of Ethnomathematics, Mathematical Modeling and Ethnomodelling, the research was also developed with ethnographic basis, since it values the closer involvement of the researcher with the subjects involved in the research in order to perceive the intimacies of the phenomenon that the study is about. We also cover elements of the historical context of Arraias, its emergence, its history, its population and traditions, as well as its customs, its colonial architecture, and the quilombola communities that exist in the region. We present the proposal of Ethnomodelling, with a field survey in the cemetery, information collection through interviews with people of the city about the construction of the cemetery and interview with Mr. Domingos de Sousa, a 95 year old man who participated in the construction of the cemetery wall from the beginning to the most current work in 2017. We observe mathematical ethnomodels present in the construction of the wall of the cemetery relating them with existing mathematical models, as well as the mathematical definitions of these models.
