Geogebra software as a tool for teaching maths Geogebra in maths teaching

In the course of this work, we sought to answer the following question: can the Geogebra software be effective in acquiring mathematical concepts and motivating students in the first year of secondary school at Colégio Estadual Professora Joana Batista Cordeiro to learn the subject? To this end, a bibliographical study was carried out on authors in the field of information technology applied to education, making use of software in teaching, in particular Geogebra. After the bibliographical study, three didactic sequences were drawn up, involving the mathematical content of Plane Geometry with the Geogebra software, which were applied to students in the first year of secondary school at the Colégio Estadual Professora Joana Batista Cordeiro, during the Supervised Internship III course. Questionnaires were administered to the students to analyse their opinions of the software and to some maths teachers. The results showed certain limitations for maths teachers, which prevented them from incorporating certain innovations into their lessons. From the students' responses, it can be concluded that the Geogebra software is considered an effective tool in the teaching and learning process.
