Tópicos motivacionais para o ensino médio

Abstract

This work had as main objective to bring association between different contents, since they often seem to be disassociated. This enables the student to produce greater meaning, so that he is always motivated to review all mathematical topics. In some situations studying the discipline may become a little arduous. We can show how important it is to see the same exercise / content from different points of view, using different solutions to reach a conclusion, to show the student how important it is to try to solve the same exercise using different ideas / concepts, so that he can draw his own ideas. Own conclusions. We relate functions for the deduction of planar / spatial geometry formulas, we present some exercises and application ideas to improve students’ understanding of logarithms, work on analytic geometry by reviewing flat geometry and geometric constructions, and use matrices to solve some exercises. By relating all these topics we can show the student the technique of algebraic reconstruction, which is the algorithm of a computed tomography machine. We use this technique in two different ways so that the reader realizes that in some situations a matrix approach is more efficient than the analytical approach.
