Uma sequência didática sobre retas no espaço a partir da coordenação de registros de representação

Abstract

The development of this research, based on the theory of Raymond Duval, aimed to verify the contributions of a didactic sequence based on the Theory of Registers of Semiotic Representation, for the learning of lines in space by higher education students. For that, a didactic sequence was elaborated, contemplating activities on vector and parametric equations of lines in space, as well as on lines parallel to the coordinate axes, using the GeoGebra software. This sequence was applied in two synchronous interactions to academics participating in a teaching project offered in 2021 at the Federal University of Pampa. This is a qualitative research in the case study modality, whose subjects were six academics from different courses at this university. The analysis of the productions of these academics showed that the elaborate sequence allowed them to convert different registers of representation of lines, such as algebraic, graphic and in natural language, favoring the learning of the contents worked.
