Perspectiva de uma aula usando a modelagem matemática: Astrolábio

Abstract

The present work presents elements about Mathematical Modeling as a teaching strategy for Mathematics, focusing on trigonometry, with the objective of constructing an instrument for measuring heights. The research was conducted with high school students in a full-time class in the city of São Sepé, Rio Grande do Sul. It was carried out in two classes, each lasting fifty minutes. The central idea of the research was to conduct a unique lesson for the author of this work, in order to have the opportunity to use a different methodology, experimenting with another way of teaching and, perhaps, arousing a greater interest from the students. This would enable the students to learn through a methodology that involves solving and interpreting problem situations. Thus, as indicated in studies by other authors, this research also confirmed that Mathematical Modeling can help promote better learning that is contextualized and produces meaning for the students. The purpose of this work was to invite the students to make the astrolabe instrument, then go to the schoolyard to collect the data needed for calculations. Afterwards, they would answer some exercise questions, which would be important for the conclusion of this wor
