Atividades interativas com o GeoGebra: uma abordagem introdutória ao estudo de geometria analítica

Abstract

This paper presents a sequence of interactive activities with the dynamic mathematics software GeoGebra, covering all major analytical topics for high school geometry. The activities are addressed here in the form of tutorial so that even users who are not familiar with the software can run them without difficulty. The work also highlights the advantages of making use of technological resources such as computer software and dynamic geometry and mathematics in mathematics teaching bringing a positive account of lived in a high school in the city of Morada Nova - CE Experience. The sequence of activities mentioned here arises from simple activities of every topic of analytic geometry for high school and move on to problems essentially flat Euclidean geometry that are solved using the analytical method, adopting an appropriate system of coordinates, allowing the active participation of students in their learning by building and manipulating the objects studied with GeoGebra and use a different reasoning to solve the problem. Finally some activities arise loci that allow the student to modify figures and verify the preservation of their property. The proposed work is an attempt to provide for an additional teacher and differential for teaching analytic geometry in high school that can be a source of motivation for the student and that allows to realize more clearly the strong relationship between algebra through and geometry.
