ETNOMATEMÁTICA: UMA ABORDAGEM SOBRE ÂNGULOS POR MEIO DO JOGO AFRICANO BORBOLETA

Abstract

This research proposed a methodological approach in the perspective of Ethnomathematics through the African butterfly game of Mozambique. This methodological proposal links African culture, through the use of the butterfly game, with institutional mathematical content. The objective is to analyze the methodological effectiveness of using Ethnomathematics and games for teaching mathematics to understand angles. The main theoretical contribution that supported this research is from Ethnomathematics with Ubiratan D’Ambrósio. The research has a qualitative character and was developed with ten internal students, students of the 1st year of High School at Institute Federal Goiano Campus Urutaí. It had three stages: application of a questionnaire 1; presentation of African culture, application of the game and development of mathematical activities; application of questionnaire 2. There were common issues in questionnaire 1 and 2 that allowed to analyze the effectiveness of this methodology. The results obtained in questionnaire 1 portrayed the difficulties presented by students in understanding angles and after the development of activities, it was noticed that the use of the African game favored the learning of the mathematical content worked, in addition it promoted the recognition and appreciation of culture afro brazilian. Thus, it was possible to realize that combining games and Ethnomathematics for teaching angle content was effective for this study.
