A abordagem do conteúdo porcentagem em livros didáticos segundo os cenários para investigação

Abstract

The didactic book has become an important didactic tool, especially in what concerns the teaching of Mathematics. Therefore, in this work, we are interested in investigating "What research scenarios, from Skovsmose's perspective, can be related to the mathematical statements of percentage of textbooks". Thus, we aim to analyze how two textbooks, one of the fifth and another of the sixth year, address the content Percentage according to the perspective of Skovsmose learning environments. We have found that books focus on exercise scenarios, although the fifth year book considers many situations with references to semi-reality. We also propose changes in situations of books for the development of research scenarios, more specifically, Mathematical Modeling activities.
