Produtos técnico-tecnológicos e atividades matemáticas: possibilidades para produção de significados em aulas de matemática

Abstract

In the present work, we have the following research question: how Technical/Technological Products (PTT), produced in professional master's degrees, can contribute to the production of mathematical meanings? We use a qualitative approach involving the analysis of PTT, so that we can approach the reality of the studied objects, as well as carry out a bibliographical survey on the subject. As for the methodological procedures, our research is divided into a few moments. In the first, we chose the PPGECEM-UEPB website and cataloged twelve PTT from the A1 area (Mathematics Education), more specifically, from the Reading and Writing in Mathematics Education – Research Group (LEEMAT) in a clipping of the 2017-2020 Quadriennium. Then, we analyze which PTT approach mathematical content in different ways, whether with exercises, activities, among others. This new filtering resulted in nine PTT that were analyzed in our research. Based on Peirce and Duval's studies, we created semiotic criteria to analyze the nine PTT cataloged in the A1 area, focusing on the presence of how the mathematical activities, represented in these products, can help in the production processes of mathematical meanings. The results indicate that PTT can handle two or more different representation registers, which can allow teachers and students to assign meanings during the teaching and learning processes of mathematical content. As for the linguistic, semiotic, representative, contextualized look that we put in these analyzed PTT, we understand that these become possibilities, among other possible ones, to understand how some products can contribute to the production of meanings involving mathematical knowledge. This work leads us to conclude on the importance of thinking about materials that, in a planned way, aim at the construction of mental structures that can help in the development of mathematical understanding.
