Uma proposta metodológica para o ensino de matemática na perspectiva da resolução de problemas em etnomatemática: o cultivo do abacaxi

Abstract

This Course Completion Work (CCW) aims to present a methodological proposal related to the ethnomathematical knowledge of farmers in pineapple cultivation, from the perspective of Problem Solving. The content of this research was developed in four stages. Firstly, a study by TCC de Silva (2020) was carried out, entitled: Pineapple cultivation and Ethnomathematics: relations with the thematic units of the BNCC, to identify the main information that supported this research. In the second stage, we identified the mathematical procedures that the farmers involved in Silva's (2020) research use in the pineapple production process. In the third stage, we analyzed the work of Silva (2020) to identify the relationship between farmers' mathematical knowledge and BNCC skills. In the fourth stage, we present a didactic sequence aimed at teaching Mathematics from the perspective of problem solving in Ethnomathematics. Due to its focus, the study is qualitative research, exploratory in nature and, regarding the form of the methods used, a bibliographic study. Based on the study carried out and readings of the main works and researchers, such as Dante (2011) and Ubiratan D'Ambrosio, we propose a didactic sequence using problem solving to expand students' knowledge about Quantities and Measures, which addresses perimeter calculations and area, relating them to the ethnomathematical knowledge of pineapple producers in Itapororoca – PB, seeking to contextualize Mathematics to promote greater interest among students. With this proposal, we intend to provide teachers with the opportunity to understand how to improve the approaches present in textbooks for teaching Quantities and Measurements and that, by using problem solving as a teaching resource, they can create challenging situations that promote reflection and the search for solutions within the students’ real context. This makes it possible to help students understand mathematical concepts and realize the importance of Mathematics in their lives. We believe that this approach can contribute to more effective pedagogical practice and more meaningful student learning.
