Um estudo sobre a construção do conceito de polígonos por alunos do 6º ano

Abstract

This research identifies and analyzes ideas that emerge from the application of different technologies in the learning of geometry, especially, in the conceptual construction of polygons. It is understood as different technologies oral language, writing and informatics, this linked with information and communication technology (ICT). An implementation was conducted through the use of evaluative chips, with the manipulation of Tangram and other manipulative materials and with the free software Geogebra. The analysis was focused on the production of students (11-12 years) in the sixth year of elementary school at a public school in Seropédica, State of Rio de Janeiro. The results show student’s ideas (drawings, symbols, figures, straight lines) in the different learning situations implemented and some relations (having the form of, looks like) that emerged in their answers and interactions concerning polygons. The research contributes with mathematics classroom in two strands: the suggestions of activities and the exemplifications of student’s notions that can be improved by the teacher on the work with polygons.
