Emoções dos usuários em vídeos educacionais : perspectivas analíticas para a produção de MOOCS

Abstract

Considering the constant technological growth, which involves different areas, including the way of disseminating knowledge, the growth of online education modalities is remarkable. The Massive Open Online Courses (MOOCs) online courses, massive and open, are having greater visibility, becoming essential to empower people by promoting a new teaching method. The use of videos is common in online teaching, videos reach emotion rather than reason, emotions being capable of accelerating or disturbing learning. Therefore, this study aims to understand how the presence of certain characteristics in educational videos directed to a MOOC can influence the emotions of users. The development of the research took place in four stages, the first being a bibliographic review and definition of the method for inferring emotions, the chosen method was the inference from facial expressions (through the use of the EZ MMLA ToolKit) and application of a questionnaire after viewing each video. Subsequently, the evaluation of the emotions of the users when watching the videos was carried out, four videos made available in a MOOC were chosen, where the first contains an expository class, the second presents an animation with synthetic voice narration, the third is similar to the second with narration performed by human voice and, finally, the fourth video is a tutorial. The third stage was the analysis of the data obtained through the inference of emotions. Finally, based on the analysis, a guide was created with tips on creating videos for MOOCs. The best accepted video was the fourth video that presents the tutorial and the least accepted was the second video that brought the synthetic voice narration. The emotions observed were, for the most part, sadness and neutrality, showing a limitation of the tool used, which considers only the basic emotions: joy, sadness, anger, fear, disgust, surprise, and an emotion of neutrality when the expression does not fit the criteria. basic emotions. This demonstrates that the use of an inference that considers secondary emotions could enable a more assertive analysis.
