Estatística no ensino fundamental e médio: resoluções de questões utilizando o geogebra e planilhas eletrônicas

Abstract

This work proposes the use of technological tools to solve descriptive statistics exercises. As a proposal for a teaching and learning method, using GeoGebra and LibreOffice Calc softwares, selected exercises were solved, and in some cases presenting their geometric and graphic representation and the integration with other contents in an interdisciplinary way. The technological tools have resources that help in understanding the concepts of statistics, as well as their visualization, and this facility was one of the differentials for using them in the proposed resolution of the exercises. In each exercise, what the statement requested was initially resolved and, after the resolution, the discussion of the same was expanded, by means of other related questions, graphical presentation of the result or interrelation with other contents. Using graphs displayed in the media for analysis, it was proposed to revise it for the initial analysis and subsequent correction with clearer and more informative information. It is verified that the technological tools have a variety of options that can facilitate the understanding of the concepts of descriptive statistics. The appropriation by teachers of this teaching and learning method contributes to the inclusion of students in the process of analysis of results, in the presentation and questioning of researched data.
