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

Abstract

The need to think about new methodologies for teaching Mathematics, especially fromsubjects related to students’ daily life, motivated the accomplishment of this work, throughthe Ethnomodelling, which aims to identify mathematical ethnomodels present in theconstruction of the wall of the Cemetery and its square of the city of Arraias -TO providingthe knowledge of part of the local reality. Considering that the knowledge acquired bycultural groups transferred from generation to generation can be important tools forstudents’ learning, we have prepared a proposal of Ethnomodelling that allows to observesome ethnomodels and to use them as didactic resources. This research was developed on abibliographic basis on the theoretical basis of Ethnomathematics, Mathematical Modelingand Ethnomodelling, the research was also developed with ethnographic basis, since itvalues the closer involvement of the researcher with the subjects involved in the research inorder to perceive the intimacies of the phenomenon that the study is about. We also coverelements of the historical context of Arraias, its emergence, its history, its population andtraditions, as well as its customs, its colonial architecture, and the quilombola communitiesthat exist in the region. We present the proposal of Ethnomodelling, with a field surveyin the cemetery, information collection through interviews with people of the city aboutthe construction of the cemetery and interview with Mr. Domingos de Sousa, a 95 yearold man who participated in the construction of the cemetery wall from the beginningto the most current work in 2017. We observe mathematical ethnomodels present in theconstruction of the wall of the cemetery relating them with existing mathematical models,as well as the mathematical definitions of these models.
