Problemas do 2º grau: Uma proposta de sequências didáticas sob a perspectiva da Metodologia de Resolução de Problemas.

Abstract

In this work will go through a study on the contributions of didactic sequences for solving 2nd-degree problems. The research motivation came from the concern, as a public school teacher, in which, it was noticed the studentsŠ memorization process to solve problems of diferent kinds. Therefore, we propose a research question: How can didactic sequences, involving the Problem-Solving methodology, contribute to the learning of 2nd-grade problems? The main objective was to develop a proposal of didactic sequences seeking to strengthen the strategies for solving problem situations in 1st-year high school classes. At the same time, a historical and bibliographical survey was carried out, proposing didactic sequences that would show the distinctive approaches to solving 2nd-degree problem-solving situations and developing them, as well as identifying and discussing their contributions. It is expected that the experience of the didactic sequences tends to favor signiĄcant learning, promoting the understanding of the content covered. As has been noted, it can contribute to the teaching of mathematics, a long with to other future investigations.
