A utilização dos softwares Geogebra, Winplot e K3dsurf no estudo das superfícies quádricas: uma experiência com alunos do curso de licenciatura em matemática

Abstract

The present work had as general objective to present a study capable of contributing to and facilitating a learning of concepts of Analytical Geometry and geometric development of three - dimensional objects, using the computational software Geogebra, Winplot and K3DSurf. The study was developed with the students of the discipline of Differential and Integral Calculus III, a course of Mathematics Degree, of the Federal University of Paraíba / Campus IV, in Rio Tinto-PB, appearing as an element of support to the learning difficulties that Students do not speak On the study of quadrilates. The methodology used for the development of the research is characterized in relation to objectives as exploratory and descriptive. As for the technical procedures used are characterized as the bibliographic research and case study and in relation to the method of approach, are characterized as a qualitative and quantitative research. The instruments used in the data collection of the research were performed with the help of softwares and a diagnostic questionnaire, containing twenty closed information. Regarding the results, it was observed that students even being in a Degree in Mathematics in some difficulties learning concepts of Analytical Geometry, specifically not referring to the visualization and graphical construction of surfaces. However, the data obtained on the application of the activities related to the software Geogebra, Winplot and K3DSurf are characterized as an instrument that contributes in a significant way so that the difficulties are elucidated. It was also verified that these softwares facilitate, mainly, a graphical perspective of the surfaces, besides allowing the study of the elements and properties of the quadric, from its potentialities tools of construction and animation. Still among the results, the students can opine on the use of the softwares to study mathematical contents in other disciplines of the course. All software related to Geogebra, Winplot and K3DSurf, also help and facilitate learning in other disciplines of the Degree in Mathematics.
