O Impacto dos gestos de Agentes Pedagógicos Animados na compreensão de dicas pelos aprendizes

Intelligent Tutoring Systems (ITS) are powerful computing tools for supporting learning, since they offer customized assistance. However, in most ITSs, the text hints presented by the tutor when student is stuck are not very clear, because they have little connection with the system's visual elements. In this paper, we evaluate if the use of gestures by an APA for explaining hints about equation solving improves the student's understanding of the related abstract concepts. The results of a qualitative evaluation with 4 students demonstrated that students understand more correctly the hints and preferred to use the tutor version with the agent that employs gestures.
