O uso das transformações geométricas e de softwares de geometria dinâmica no ensino de Matrizes e suas operações

Abstract

This work is a pedagogical alternative for teaching arrays and their operations. Traditionally, textbooks dealing transactions between matrices based solely on algebraic point of view, in an abstract way and contextualization artificial. The approach proposed here is conducted through the study of geometric transformations in the plane. Thus, it is possible to provide a geometric interpretation for each matrix. One advantage of this choice is to use the power of Dynamic Geometry software, that make the process of teaching and learning more exciting, allowing the student to have a less passive during this process. Thus it is expected that it ceases to be a mere spectator of rules and concepts and become responsible for its knowledge production, thereby helping to demystify the learning of mathematics.
