RELATO DE EXPERIÊNCIA DE ESTÁGIO EM MATEMÁTICA NO ENSINO MÉDIO DA REDE ESTADUAL DE EDUCAÇÃO UTILIZANDO O SOFTWARE GEOGEBRA

This work presents the report of an experience of the supervised internship discipline, of the Mathematics Degree course, which was carried out in the second year of High School, in a state school. For the development of the activities, some studies developed by Wankel an (2012), Dullius and Quartieri (2015) and Ibraihm (2016) were studied, for the theoretical foundation of this research. In addition, the National Curriculum Parameters for Secondary Education was analyzed in order to better understand this level of education. Six classes were previously attended in the class in which the internship took place, to survey the students' previous knowledge. The content worked on was Trigonometry in the Rectangle Triangle, where the content was related to the students' daily lives, using the Geogebra mathematical “software” so that students can simulate different trigonometric relations in order to enrich learning. At the end of the work, an individual written assessment was carried out, in which more than 60% of the class scored above average.
