O desenvolvimento de conceitos geométricos por meio do aplicativo geogebra: contribuições à compreensão do teorema de Pitágoras.

Abstract

It is known that nowadays, students live in constant interaction with digital resources, which they do not realize that they can influence significantly in their training as citizens. With the technological expansion, technology has grown to the point of entering in educational institutions and has been used in various areas of knowledge. Many mathematics teachers in particular are adopting this kind of methodology in order to build knowledge of their students in specific concepts. Then, through the GeoGebra software in application available for smartphone, we apply some activities, which are aimed at the construction of geometrical knowledge in classes for the Pythagorean Theorem. Thus, in this study, we sought to answer the following question: What are the contributions of Digital Technologies (smartphone and GeoGebra software) to the construction of geometrical knowledge for the construction of the Pythagorean Theorem with students of the 1st year of high school? From this question, our objective was to investigate the construction of geometrical knowledge in classes for the "Pythagorean Theorem", through the GeoGebra dynamic geometry software available in the smartphone applications. We seek even with this technological tool, promote visualization of geometric reproduction through the software and make significant and dynamic mathematics classes. The research was conducted in a public school in the city of Barra de Santa Rosa/PB in a class of the 1st year of high school. Students studying in the morning, however, the search was on to turn in time from 13h30 to 15h00, in three days of august. Of the 22 students enrolled in the 1st year, 18 agreed to participate. We believe that using technology is far from being a solution to the problems faced by schools, but we noticed that they bring with them, significant considerations for the life of the student, allowing them to both learning content taught by the teacher, as well as the new pedagogical tool used.
