Tecnologias no Ensino de Geometria Plana: um estudo à luz da teoria dos registros de representação semiótica com o auxílio do Geogebra

Abstract

This dissertation investigates the teaching of Geometry in the light of Raymond Duval's Theory of Registers of Semiotic Representation. using Geogebra as a pedagogical tool with high school students from a private school in Bacabal, Maranhão. The research adopts a mixed approach, combining qualitative and quantitative methods. Teaching activities were applied to two groups of students, group A, with activities mediated by technologies, using Geogebra, and group B, which followed the method traditional. The results show that the use of digital technologies promoted motivation and greater engagement of students in the activities in relation to geometric concepts. The use of Geogebra revealed a significant increase in the enthusiasm and autonomy of the students who used this application, suggesting that the integration of multiple representation registers facilitates a better apprehension in the study of mathematical objects. The survey also highlights the need for continuous training for Teachers in the effective use of these technologies, as well as teacher training institutions, need to focus more and more efficiently on the use of technologies as pedagogical tools
