Software livre aplicado ao ensino de números complexos

Abstract

This monograph deals with the teaching of mathematical content complex numbers: basic properties and operations. This is an exploratory survey, whose problem was to identify what contribution the use of a free software brings to the teaching of complex numbers. The field research was a class of third year of high school in a public school. The study aimed to facilitate the teaching of complex numbers, with the use of a software support. Justifies the choice of this theme because during the course of educational practices and interviews with new students in undergraduate courses at the Federal University of Pampa, Campus Alegrete, there was great difficulty in teaching and learning of the content in question. Research walked in two senses: first, the contents were exposed through the traditional method in the classroom. In a second step, it was proposed to aid the teaching of technology, through the free software Complex Numbers in the computer lab. After implementation of the proposed school, it was found that the software used enables the meaningful learning of the content of complex numbers, enabling better visualization and graphics reinforce concepts already worked in the classroom, but the use of technology does not completely replace the prior presentation of content in a methodology exhibition.
