Abstract

This paper presents some results from a PhD research on figural treatments and mobilizations of records that were made during the resolution of a Geometry problem by Mathematics teachers. It refers to the investigation of the influence of figural records, Manipulatives (MM), GeoGebra Software (SG) and Graphic Expression (EG), in the construction and organization of deductive reasoning which involved figural visual support. The theory used for this research is based on the Records of Semiotic Representation by the French philosopher and psychologist Raymond Duval. The influence of the types of figural record was investigated with the participation of fifteen (15) Mathematics teachers from Basic Education in a town north of Paraná during the resolution of a Geometry problem-situation. Based on the data obtained, we concluded that the figural treatments to be performed are different depending on the type of record that is used, and likewise the mobilization of other records also vary according to the starting figural record used.
