Ensino de trigonometria a partir de objetos virtuais de aprendizagem: um estudo de possibilidades

Abstract

Considering the relevance that the digital technologies (DT) use has as a teaching and learning tool, especially in Mathematics, we sought to highlight possibilities and potentialities of using virtual learning objects (OVA), built in the GeoGebra software, for the teaching and learning trigonometry and trigonometric functions in high school. The material was organized as a didactic sequence in book format in online GeoGebra, which presents the objects of knowledge in a way that includes concepts, constructions and questions to be answered by students who will manipulate the OVA. This work was characterized as research of a purposeful qualitative nature, based on a pedagogical imagination (PI) exercise from the perspective proposed by Skovsmose (2015), developed by the author and seven Mathematics teachers. From the analysis, some possibilities and potential for the material using for teaching and learning the objects of knowledge covered were highlighted, in particular by providing the teacher with greater dynamics to work on the concepts explored, and the student the possibility of interacting with the material of study.
