Portables experiments to learning on electromagnetic induction, generators and motors

In this paper we will present a portables 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 learn 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 developed by the group from Rutgers University, led by Professor Eugenia Etkina. The foundation of this proposal is that student’s study and learn physical concepts similar to the way scientists work to setup scientific knowledge. Such methodology was called “Investigative Science Learning Environment” (ISLE). In this method, students are 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 present a proposal for a didactic sequence to be applied to a twelve-year high school class.
