Combinação simples: um estudo a partir da estrutura do sistema braille como ferramenta de aprendizagem no ensino médio

Abstract

This article aims to analyze the effectiveness of the teaching methodology of Simple Combination through the use of the Braille system structure, as described by Morais Filho (2013) for teaching Simple Combination presented in the postgraduate course "Mathematics in Practice." For its foundation, this research primarily relies on studies developed by Coutinho (2015) on Combinatorial Analysis and more specifically on Simple Combination, and by Fernandes and Silva (2020), which discusses the Braille system. The study adopts a qualitative approach and is based on action research. Therefore, a methodological approach was sought that directs the construction and generalization of the concept of simple combination. The research results indicate that students feel more confident using formulas; however, although they are not yet prepared for this methodological approach, they yearn for teaching that develops their reasoning and is related to their experiences.
