A lâmpada de arco : mediador para a revisão de conceitos relacionados à eletrodinâmica

Abstract

In order to dynamize and contextualize the teaching of physics in front of the electro-electronic world, we propose an educational product that is constituted of the experiment known as the "Lamp of Arc" and script referring to the experiment and other simpler experiences. All classes were carried out following lesson plans and itineraries referring to the experiments, which promoted discussion, reflection and provided the possibility of building a progressively more scientific language. Thus, the concepts of electric current, conductors, resistance, electrical potential and others, were discussed theoretically, contextualized and revised, finally, with the use of the arc lamp. We verified for a semester that a planning that contemplates theoretical classes accompanied by demonstrations and reviewed through experiments, is a possibility of overcoming the traditional classes, and we also verified that these have much to contribute to a greater attendance on the part of the students, the students' involvement in the discussions, understanding of the concepts and the possibility of contributing to the students being able to describe the concepts, and criticizing the technological world.
