A integração das tecnologias digitais ao ensino e aprendizagem de geometria no ensino fundamental – anos finais: uma proposta com foco no estudo de perímetro e área de figuras geométricas planas

Abstract

This is a research dedicated to the use of Digital Technologies (DT) as an educational tool for Geometry teaching and learning. It is justified by the social relevance for educating individuals, because of its comprehensive applicability, as well by its importance highlighted on PCN. In addition, it is substantiated by the difficulties presented by teachers, and due to the large scale results of evaluation that demonstrated that Geometry teaching issue has been left on the side lines. This researched aimed to investigate the integration of DT with the Geometry teaching and learning, focused on the study of flat geometric figures perimeter and area in the Elementary School - final years. In particular, it has been checked that the GeoGebra software usage form can contribute for studying this present subject. The investigation is featured by qualitative research approach divided into three stages 1) theoretical basis approach to substantiate the research; 2) it refers to the diagnosis and scenery characterization of DT usage in the municipal schools from Juiz de Fora (MG), in which questionnaires have been used for three different groups, namely school principals, Elementary School Mathematics teachers – (final years) and 9th grade students, 3) it is the experimentation stage, in which has been carried out a pedagogical sequence of activities embracing the studied theme, supported by the GeoGebra software, 4) last investigation stage, it is about the analysis of the undertaken activities and the research validation .Each one of these stages is backed on the theoretical suppositions of Pedagogical Engineering and the result analysis is founded on the Anthropological Pedagogical Theory. In the end of the research, it was perceived that there are many challenges to be overcome concerning the integration of DT with teaching; however we realized the effectiveness of Geogebra software to maximize the study of the perimeter and area of flat geometrical figures. In this regard, the software was offered as an educational product for activities and guidance for Elementary School teachers - final years related to the activities developed along the study.
