Objetos virtuais de aprendizagem para o estudo de cônicas: uma experiência com estudantes do ensino médio

Abstract

The term paper carried out consists of the continuation of the studies carried out by the group that was part of a research project with Scientific Initiation (IC), in which virtual learning objects (OVA) were created for teaching conics, followed by a pedagogical imagination exercise. to identify possibilities and potentialities of its use in the classroom. For the present research, a didactic sequence was elaborated from the selection and improvement of some of these OVA. A sequence of activities was organized, including making the OVA available for manipulation by students in the online GeoGebra book tool. The proposal was applied in a high school class at IFSC – located in Chapecó, with the purpose of analyzing and identifying possible contributions of the use of OVA for a meaningful learning of conics. It is an action research, with a qualitative approach in which the data produced were submitted to a discursive textual analysis from the perspective of Moraes and Galiazzi (2020). The interaction with the OVA and the possibility of investigating the mathematical contents involved facilitated the understanding of the students in order to make the material presented potentially significant. There were indications that the didactic sequence contributed to the development of students' autonomy, enabled the elaboration and confirmation of conjectures, expanded the students' geometric and algebraic visualization in relation to pre-subsumers Finally, there is evidence that the use of OVA contributed to a significant learning of the objects of knowledge addressed.
