ELABORAÇÃO DE UM CADERNO DE ATIVIDADES EXPERIMENTAIS PARA O ESTUDO DE CIRCUITOS ELÉTRICOS DE CORRENTE CONTÍNUA

Abstract

The operation of basic electrical circuits is an important issue for the teaching of physics, as much of the current technology is based on the operation of these circuits. This project aims to propose practical activities for the study of electrical circuits of direct current. The activities were applied with students from a vocational education school, for the development of basic skills, such as electric diagrams interpretation, use of digital multimeter, components recognition and circuits operation understanding. Not always available in schools a suitable laboratory to perform these activities. Thinking about it, this paper proposes theconstruction of a didactic panel that can be used in the classroom. In this panel, was set a voltage source and components. For the supply voltage was proposed the reuse of computer sources. Currently, there are many computers that are already out of use or obsolete, the reuse of these sources can be a low cost alternative for teaching materials construction. The planning of tasks aimed to foster meaningful learning, for that, the Theory of Meaningful Learning of David Ausubel was adopted as reference. All tasks and instructions were gathered in an activity book that will be available for teachers use.
