Saberes históricos da trigonometria: importância da aula extraclasse ; Historical knowledge of trigonometry: importance of the extraclass class

Acompanha: Problemas do cotidiano para alunos ; The teaching of trigonometry in elementary and high school, most of the time is represented from repetitive exercises and formulas, thus causing a lower performance on the part of the students, since they are hostages of a mechanical learning. The consequence of this is the inability to solve problem situations, in an attempt to minimize the impacts of this mechanical learning; it is common in trigonometry classes to use problems that come with everyday contextualization. However, even with this alternative, students are often unable to assimilate the content with practice. Therefore, the present study sought to observe and analyze positive points in an extra class, which was called "Field Class", based on a teaching experience that addressed the contents of "Similarity of Triangles" and "Trigonometric Relations in the Triangle.” Rectangle” in a private school in Northern Paraná, in which the teacher is one of the researchers. The methodology used in the research is descriptive with a qualitative focus. The data were collected, with the records of the 19 students of the 9th year who were separated into 6 groups, of which, later, they presented photos and reports. The results found reported an observation of the pros of a “Field Class.” Seeking thus, a direction for teachers who intend to carry out a class based on this methodology. ; A docência de trigonometria no ensino fundamental e médio, na maioria das vezes, é representada a partir de exercícios repetitivos e fórmulas, causando assim um menor aproveitamento por parte dos alunos, uma vez que estes ficam reféns de um aprendizado mecânico. A consequência disso é a incapacidade de resolução de situações problemas. Na tentativa de minimizar os impactos deste aprendizado mecânico, é comum em aulas de trigonometria a utilização de problemas que vêm com contextualizações do cotidiano. No entanto, mesmo com esta alternativa, os alunos muitas vezes não conseguem assimilar o conteúdo com a prática. Sendo assim, o ...
