Há uma constante cobrança da comunidade escolar pela inserçãode tecnologias nos processos de ensino-aprendizagem. Sabe-se que a tarefade selecionar um software educacional e inseri-lo nas atividades de sala deaula é um obstáculo ao professor. Recentemente o software Scratch vemganhando espaço em projetos escolares pela flexibilidade e benefícioscomprovados. A fim de contribuir com a formação docente, desenvolveu-seum trabalho orientado com seis professores do ensino fundamental e médio.A proposta envolveu utilizar e avaliar o software Scratch seguindo critériostecnológicos e pedagógicos. As percepções e avaliações coletadas estãodescritas neste artigo.

Based on neurology and cognitive science many studies are developed to understand the human model mental, getting to know how human cognition works, especially about learning processes that involve complex contents and spatial-logical reasoning. Event Related Potential - ERP - is a basic and non-invasive method of electrophysiological investigation. It can be used to assess aspects of human cognitive processing by changing the rhythm of the frequency bands brain indicate that some type of processing or neuronal behavior. This paper focuses on ERP technique to help understand cognitive pathway in subjects from different areas of knowledge when they are exposed to an external visual stimulus. In the experiment we used 2D and 3D visual stimulus in the same picture. The signals were captured using 10 (ten) Electroencephalogram - EEG - channel system developed for this project and interfaced in a ADC (Analogical Digital System) board with LabVIEW system - National Instruments. That research was performed using project of experiments technique - DOE. The signal processing were done (math and statistical techniques) showing the relationship between cognitive pathway by groups and intergroups.
