Investigando a contribuição de uma unidade de ensino potencialmente significativa (UEPS) no processo de ensino e aprendizagem das razões trigonométricas no triângulo retângulo

Abstract

In this article we investigated the development of student learningin teaching situations developed in a Potentially Meaningful Teaching Units (PMTU) on concepts related to trigonometric ratios in a right-angled triangle, from contents applied to physics, to identify evidence of meaningful learning. The work was based onthe Theory of Meaningful Learning and had a qualitative approach methodology, with elements of Design Experiment, with data analyzed from discursive textual analysis. Considering the principles that determine meaningful learning, we conclude that the PMTU on trigonometric ratios in a right-angled triangle has become a potentially significant material as it has been important for students' idiosyncratic cognitive structures.
