A etnomatemática e a catedral nossa senhora das mercês de Porto Nacional-TO.

Abstract

The teaching of Mathematics has undergone studies over the years with a view to teaching and learning Mathematics so that students understand this science. From this perspective, Ethnomathematics initially proposed by D’Ambrosio (1990) can be an ally for Basic Education teachers, demystifying school mathematics that is mostly considered difficult and unattractive to students. In this sense, the present research has as its object of study the mathematics present in the architecture of the Nossa Senhora das Mercês Cathedral, located in the city of Porto Nacional - TO. In this sense, we ask ourselves: What mathematics are present in the architecture of the Catedral Nossa Senhora das Mercês in Porto Nacional? To this end, we aim to understand the mathematical knowledge present in the architecture of the Nossa Senhora das Mercês Cathedral/Porto Nacional-TO, from the perspectives of those who know the history of its construction. To this end, we sought through a qualitative approach (Oliveira, 2016), based on the ethnography presented by Angrosino (2009), the data were collected through visits to the Cathedral, visits that resulted in a greater approximation of the activities carried out in the church; narrative interviews, believing that previously untold information could emerge and/or presented in books that portray the history of the Cathedral, these dialogues were recorded in audiovisual resources and subsequently transcribed; We made use of the field notebook, and the photographs of which are present throughout the text of the dissertation, which were important for identifying the mathematics present in the architecture of the Cathedral. We present the process of building the cathedral and its importance of religious faith for the community of Porto Nacional. It is observed that the idealization and construction of the Cathedral by the Dominicans contributed to the population of Porto Nacional in several areas, especially in culture, religiosity and education. In addition to contributing to the construction and installation of other Christian works such as the convent, the parish and the Sacred Heart of Jesus school. The information collected was analyzed in light of the theoretical fields of Ethnomathematics, with regard to teaching and learning processes. Thus, we identified in the construction of the aforementioned Cathedral the presence of Euclidean Geometry based on triangles, rectangles, squares, rhombuses, circumferences, semicircles, as well as polygonal lines, symmetry, angles and parallel lines. These mathematics can enhance interdisciplinary didactic actions for teaching Mathematics in schools in Porto.
