O teodolito como recurso mediador no processo ensino e aprendizagem de conceitos trigonométricos na Educação Básica

Abstract

This work has as its object of study "the theodolite as a mediating resource in the process teaching and learning of Mathematics". In this context, we seek to respond to following research problem: How can the theodolite enable the process teaching and learning trigonometric concepts in Basic Education? Thus, the hypothesis that we defend in this study is that teaching mediated by and didactic instruments promotes the expansion of student learning and interest during Mathematics classes through the use of concrete materials, such as of the homemade theodolite and the use of the Theodolite app. From this perspective, the work developed with the general objective of analyzing the importance of using the theodolite as a mediating resource in the teaching and learning process of trigonometric concepts in Basic education. We start with theoretical-practical classes with students, involving the use of the theodolite. We then guide students in the construction and application of this tool in problem situations posed, with a view to improving learning and student interest in Mathematics classes. Therefore, when considering the objective general and the problem question, this research is understood as research into field and qualitative approach. And the subjects investigated were 2nd year students high school at a state public school located in the city of Caxias-MA. For the production of data and for the purpose of making a diagnosis of knowledge already acquired by students about trigonometric mathematical concepts, a priori, we applied a questionnaire (Pre-test) covering assessment activities external Prova Brasil. After making and using the theodolite and intervention by the researcher, in which we make use of observation, new problem situations were proposed (Post-test), also from Prova Brasil, in order to observe the importance of the theodolite as a mediator in the teaching and learning process of Mathematics. At that time, the participants reported based on written textual production guided by the researcher, your opinions about the theoretical-practical classes involving the use of the theodolite in teaching and learning process of trigonometric concepts. Overall, the results of the research reveal that, in a certain way, the difficulties in understanding and appropriating of trigonometric concepts were softened.
