Ensino de física moderna e contemporânea baseado em atividades de laboratório mediadas pela utilização de um software de videoanálise e modelagem

Abstract

This work aims at the development of Open Educational Resources (OER) for the teaching of Modern Physics experiments, based on video-analysis. Modern Physics teaching strategies constitute an important theme amongst the physics education community, mainly due to the ubiquitous presence of Modern Physics in technologies that surround us. In fact, in their everyday life, teachers and students have wide access to technologies that allow them to establish connections between classroom contents and their applications. In this context, we highlight the use of computers and data analysis software, which bring about wide possibilities to overcome the monotony of science classes. Tracker is a software that constitutes an important video-analysis tool, which was developed for physics teaching based on video recording of experiments. It facilitates the design of laboratory and experimental activities, including data collection and graph preparation. Therefore, Tracker serves as a platform to integrate both Modern Physics teaching and technological tools in the classroom, bringing together two research pillars in Physics Education (Modern Physics and the use of Technology). The OER was developed in accordance to international trends in open source technologies, and it comprises videos related to three fundamental experiments in Modern Physics: Millikan’s oil drop experiment; electron charge-to-mass ratio experiment; and electron diffraction experiment. The videos were analyzed with Tracker and posted in the Internet, under a Creative Commons license. Detailed tutorials were also developed in order to facilitate in-classroom use of the materials. In addition, validation of the OER was also performed through questionnaires responded by teachers and students who used the developed material. Modern and contemporary physics teaching based on laboratory activities mediated by video analysis-and-modelling software.
