Dissertação (Mestrado em Matemática em Rede Nacional) - Instituto de Matemática e Estatística, Universidade Federal de Goiás, Goiânia, 2025.https://repositorio.bc.ufg.br/tede/handle/tede/14919The teaching of trigonometry is highly significant for enhancing the cognitive development of students, and it is necessary to seek alternatives with the aim to clarify doubts and improve the comprehension of trigonometric concepts by the students, that are extremely valuable in society. It is Necessary to utilize computation tools in the teaching of mathematics in basic education, and adapt the educational practices in response to the demands of contemporary society. Thus, the necessity take advantage of the opportunities offered by the technology for enhancing the learning of students. In general, it is observed that the students have had progressively earlier contact with digital media and interactive environments. In this contexto, it is became essential to discuss and incorporate this technologies in the school environmental, given that such resources are naturally attractive for the young audience, and can contribute of meaning way for the learning process. The objective of this study is to present an applied research on the concepts of trigonometry in a dynamic way, so that this branch of mathematics can be taught for the students through dynamic mathematics applications and didactic sequences. For this purpose, the application implemented in this study is GeoGebra, that provides extensive pedagogical possibilities, providing a well-structured organization on its online platform. This work is organized in its main structure through didactics sequences with should be developed with the support of GeoGebra. These instructions sequences offer better organization in the writing of the work, in a structured and coherent way.Acesso Abertohttp://creativecommons.org/licenses/by-nc-nd/4.0/TrigonometriaGeoGebrGeometria dinâmicaTrigonometryGeoGebraDynamic geometryCIENCIAS EXATAS E DA TERRA::MATEMATICADissertação
