Construção de gráficos de barras a partir de diferentes recursos: lápis e papel e software excel

Abstract

Abstract

This research aims to investigate the learning of students in the 5th grade of primary school in relation to understanding the construction of graphs from tables with pencil and paper or with the Excel software. Students from 4 classes in public schools in Paulista / Pernambuco participated in a diagnostic test, a teaching sequence and a post-test. Two classes participated in this intervention using pencil and paper to build graphs and the other two classes using Excel software. In these interventions, the construction of graphs was experienced from simple and double entry tables and with different numerical quantities. Qualitative advances were observed in relation to the representation of the data in a bar graph for the two groups and there was no statistically significant difference between the resources used. Each type of resource contributes more to a type of skill, which leads us to believe that both should be stimulated in the teaching-learning process of statistical knowledge.
