Experimentos portáteis para aula sobre indução eletromagnética, geradores e motores

Abstract

In this work we presented a portable experiments in order to approach the concepts of electromagnetic induction to Basic Education students. The materials used to perform the experiments are easy to acquire, and the set of them can be purchased in the form of an experimental kit, easily transportable. The proposal is that students learned the concepts through classroom discussion and the execution of experiments, with greater emphasis on interactive classes over lectures. For this, we were inspired by the Methodology ISLE developed by the group from Rutgers University, led by Professor Eugenia Etkina. The foundation of this proposal is that students studied and learned physical concepts similar way scientists work to setup scientific knowledge. Such methodology is called “Investigative Science Learning Environment” (ISLE). In this method, students were introduced to the scientific method, in high school, in a concrete way where observation, proposition and refutation of hypotheses are fundamental for creating a model for the physical phenomenon studied. To evaluate the methodology and use of the portable experiment, we presented a proposal for a didactic sequence to be applied to a twelve-year high school class.
