Geometrias espacial e plana: Uma análise dos significados revelados por meio dos registros de representações semióticas

Abstract

This research, called Spatial and plane geometries: an analysis of the revealed meanings on registers of semiotic representations, consists on a qualitative investigation, pedogogical type, developed with seventh grade students of a public school in Cachoeira dos Índios, countryside of Paraíba. It was guided by the following question: “What meanings about spatial and plane geometry can be identified, based on the registers of semiotiotic representation used by estudents of the final years of basic education, on the resolution of questions involving polyhedrons and polygons?”. The research aimed to analyse revealed meanings on the semiotic representations registers produced by students on the final years of basic education, during spatial and plane geometry classes and, more specifically, meanings envolving polyhedrons and polygons. On this intent, we developed, with the research subjects, a teaching sequence, focusing the geometric contents polyhedrons and polygons, through manipulable materials exploration, building and rebuilding of these objects, besides drawning and writing and oral productions. Data collect was done with notebook, students activity sheets, videos and pictures. The revealed meanings were analysed based on the Registers of Semiotic Representation Theory of Raymond Duval, presenting as results the eminence of the more remarkable meanings, the students comprehension about the studied objects and the verifying of the relation between presented meanings and use of registers of semiotic representations.
