Uso de experimentos e contextualização da eletricidade em turmas de 3º ano

Abstract

This work consisted in an experiment of electricity in the classroom, intending to attest to the impacts of this practice in the improvement of the teaching-learning process. For the measurement of effects, three blocks of questions related to the content of electricity traditionally taught and through the experimental demonstrations were applied. The first and second blocks were applied before and after the experimental demonstrations. The third question block was applied only once, after all the experiments (real and virtual). By analyzing the data obtained, there was a tendency to improve the number of correct answers, although a significant number of students continued to respond incorrectly. It was understood that the full success of the use of experimental demonstrations depends on the existence of a group in which the students present discipline and real interest for the school learning and that this is a reality that can be reached by the teachers of the public schools.
