Contextualizando cultura e tecnologias: um estudo etnomatemático articulado ao ensino de geometria

Abstract

This dissertation is the result of the studies carried out in the master 's program. It is the result of the course of the Master' s Degree in Science and Mathematics Teaching at the Federal University of Pelotas, based on a necessity of contextualize Geometry, involving Pomeranian culture. It is relevant because it is a qualitative research and is linked to the investigation of algebraic geometric knowledge in the predominantly rural architecture of the city of São Lourenço do Sul. This study is related to the social context that comes to make use of the ethnomathematics described by D'Ambrosio (2013), being the guiding line of this work, in the cultural view of geometric knowledge, It is based on the details of the typical Pomeranian houses of the region Where the research was carried out. As a way of materializing the study, the students performed a collection of photographs of these constructions, in order to analyze the geometric forms present in them, as well as to make calculations of areas and perimeters. The GeoGebra software was used as an auxiliary technological resource , to carry out the research, where the study was carried out with the similar projections of the architectures, after that ,with mathematics help, where the calculations were made.The main objective of this study is the rescue of the Pomeranian culture by means of the valorization of Pomeranians traces present in the architecture of the constructions, whose details contemplate the geometric forms, that can constitute agents of promotion of the Geometry teaching, with the use of the computer resources, through GeoGebra software. In this sense, the choice of the Ethnomathematics program was an important theoretical choice for working with a process and culturally contextualized teaching and learning. In order to identify and calculate geometric figures (square, triangle, rectangle, rhombus, parallelogram, trapezoid, etc.), the development of this research is intended to portray a differentiated activity in the approach to the content of flat geometry.I believed that this work proposed a stimulated study for the students, and carry throughout their lives another way of integrating mathematics into their reality, rescuing the past and still experiencing culture in a differented way
