Matrizes: propostas de aplicação no ensino médio

Abstract

In this paper, we intent to make an approach of some matrix application that we judge possible to introduce in basic level education, in order to give students a broader vision of the real world mathematical utility, contributing to make a more dynamic and attractive mathematics teaching. The applications are cryptography, Markov chains, graphs, plane transforms and linear systems. We realized that the treatment given in basic textbooks to this topic is, frequently, sketchy and superficial, scarcely happening to make activities encompassing these topics. However, this is a very rich and broadening topic, that can be related to many areas of human knowledge such as Administration, Economy, Biology, Computer Science and Physics, working as an useful tool to educational interdisciplinarity . Then, it is possible to explore the matrix concept, its representations, its operations, properties and definitions to contextualized problems. Along this paper, we collect several activity suggestions found in articles, essays and Linear Algebra textbooks.
