O ensino da trigonometria em turmas de 9° ano do ensino fundamental sob a perspectiva da resolução de problemas.

Abstract

Faced with the great and necessary transformations that society has been undergoing, mathematical education cannot be left behind. Therefore, the need for changes and improvements in the teaching and learning process are indispensable. Thinking about it, the main objective of this research study was to answer the question: how does the Problem Solving perspective contribute to the mathematics’ teaching and learning of trigonometric ratios in the rectangle triangle in 9th grade classes of elementary school? The approach was carried out with 11 students from a private school in the city of Nova Floresta-PB. The kind of research used was a qualitative nature study, because it allows a better interpretation of the data in the process of analyzing and discussing the results that were collected from the application that was done. With this, it was possible to perceive the efficacy of the perspective of problem solving in related to the study object. This way, we bring some reflections about the positive and negative points found from the practice performed.
