Learning by Experimentation: The Calculatora Estatística Visual

Abstract

Learning from experimentation is the basis of the pedagogical theory called Constructivism. The system Calculadora Estatística is a Web-based tool to reinforce learning of statistical techniques, developed by the application of that theory. From a study about human-computer interaction, its newest version, the Calculadora Estatística Visual, was designed with visual programming features to provide an iconic and flowchart-based interface that allow users visualizing the steps necessary to perform a statistical analysis. It is composed by an interface that works on a statistical package to check users requests in order to guarantee the correctness of the statistical operations sequence.
