Tecnologia digital no ensino da matemática para os alunos do 9º ano: uso do geogebra nas construções dos segmentos proporcionais da geometria plana

Abstract

Faced with schools that have few computer resources, students who are disinterested in their studies, with little participation in school activities, and the need to bring mathematics teaching that can add meaning to students' lives. students, the general objective of this research is to show the contributions and limitations of a teaching-learning proposal in the face-to-face modality using Geogebra for the content of proportional segments in plane geometry for 9th grade students. geometry for students in the 9th grade of basic education. The methodology was The methodology was qualitative and was applied in a school in the south of Manaus. 9th grade class. The geometric constructions presented by the students and the level of satisfaction shown in the class and described in the final questionnaire the final questionnaire, it can be seen that the students developed participatory attitudes, such as attitudes, such as autonomy, and there was an improvement in the performance of the concepts of proportional segments in plane geometry, as shown in the work carried out. Key words: Technology. Software. Proportional segments.
