Visualização e representação geométrica de raízes de funções polinomiais: uma proposta didática

Abstract

The main teaching support for geometric visualization of roots of polynomial functions is GeoGebra, which is a dynamic mathematical technological software designed to teach as well as learn mathematics. Its interface allows users who access it to interactively visualize the results of their constructions. In this context, based on the teaching experiences of the author of this dissertation, the main objective of this present research is to present how we can, through simple technological software, mathematically deepen the study of polynomial functions, guaranteeing geometric visualization as the main teaching methodology. To this end, several concepts from other authors are presented, whose dissertations have a similar theme to the initial idea of this research. Finally, the final conclusions present how much the new teaching methodology designed to have as its main focus the use of GeoGebra software used as a methodological tool impacted on the students’ teaching-learning process.
