Inovação no processo de ensino e aprendizagem de álgebra linear usando o software geogebra

Abstract

This paper presents pedagogical strategies using GeoGebra software to innovation the learning and teaching process of some topics of Linear Algebra, such as: vectors, matrices, orthogonal projections and the least squares methods. The approach to these and other topics using GeoGebra software is made specifically in the CAS window (programming environment witha simple language and accessible to all students), graphic window (environment for sketching graphic of two and three dimensional) and algebra window (environment for editing and storing scalars, functions, vectors and defined variables). The main commands used in the study of these topics will be presented together with the resolution and graphical analysis of three linear systems. To finish, the least squares methods will be used and implemented in software with the objective of finding the best function that approximates a set of experimental data obtained in physics laboratory. The use of the software in the learning and teaching process of Linear Algebra has helped students to better understand some concepts worked in the classroom, besides ensuring a more pleasant and interesting study
