Uso e divulgação do software livre Tracker em aulas de física do ensino médio

Abstract

This work relates to videoanalysis as a learning tool in high school Physics classes. It presents results on the use of free software Tracker, which aims at motion video frame by frame measurement and analysis. Our main goal is to provide alternatives to the lack of physics teaching laboratories, which is a major problem faced by many Brazilian schools. Videoanalysis is a powerful tool made possible by common digital cameras, including the ones present in mobile phones. Videos are recorded allowing for data collection and analysis with Tracker together with any usual spreadsheet software. The project was applied to students attending the first year of a public high school in Curitiba. The school is located in a region characterized by poverty and social risk. The obtained results were assessed by a report consisting of six questions, related to the subject freefall, proposed to the students. The developed material offered students a different learning perspective, aiming at improving students’ motivation towards learning Physics. The lectures were also an efficient way of stimulating critical thinking together with inclusive use of technology in the school environment.
