Teorema de Pitágoras na interface do material concreto

Abstract

The Pythagorean theorem is one of the most important mathematical foundations for generalizing various mathematical situations and calculating distances. There are currently several ways of demonstrating its veracity, but its teaching is often restricted to simply applying the formula in an inflexible and abstract way, without contextualization, which is an aggravating factor in mathematics teaching. In view of the attention that the subject demands and arouses, this study aimed to analyze articles and dissertations whose object of study are concrete materials, with a view to discovering what contribution(s) the use of these materials makes to the teaching of the Pythagorean Theorem, in order to identify the relevance given to this theme in scientific research and contribute to studies of methodologies for teaching the Pythagorean Theorem. The research was based on a bibliographic review of the literature, whose search was carried out in the Brazilian periodical databases Google Scholar, the Portal of Periodicals of the Coordination for the Improvement of Higher Education Personnel (CAPES) and the Brazilian Digital Library of Theses and Dissertations (BDTD), with a time frame of 2010-2023. At the end of the search, only 4 papers were selected, and the analysis showed that the use of concrete materials in the teaching of the Pythagorean Theorem contributes significantly to the process of contextualization and, consequently, to the understanding of this content.
