Agentes pedagógicos animados : desenvolvendo uma retroalimentação (feedback) não verbal.

Abstract

This work intends to insert a new characteristic into the project “The Use of Cognitive Styles and Pedagogic Agents in the Teaching and Learning Process”, realized at UNISC (University of Santa Cruz do Sul) using the non-verbal feedback of the animated interface agent Dóris through the representation of emotions (joy, sadness, surprise and normal state). The work aims at turning the Intelligent Tutor Systems – ITS - more affectionate, thus improving the income of the users of these kinds of teaching environments. An improvement was obtained in the right-gettings when the environment was used in the presence of non-verbal communication. Even being a small improvement, it may be confirmed through non-parametrical statistic tests such as Square-CHI and Fischer’s Exact , methods employed with small samples.
