A abordagem do conceito de energia através de experimentos de caráter investigativo, numa perspectiva integradora

Abstract

The physics teaching is being criticisms target, because, beyond emphasize mathematicians aspects, it presents the concepts in out of context and unarticulated way, especially the energy concept. So, this article had as objective to promove more articulation between the different kinds of energy concepts by means of use of experiments. The development of this article is fundamented in the Theory of Personal Constructs, by George Kelly (1963), and it uses the repertory grid and the concept maps as instruments to collect data. The didactical intervention was structured in six meetings, starting with the pre-tests application, aiming to identify the students initial concepts in relation to the broached themes, followed of experimental activities, aiming the fragmentation observed in the students cognitive structure in relation to the energy concept understanding. Finally, pos-test were applied to verify possible changing’s happened in the students construction system. The results indicated that the students passed to articulate more concepts of different kinds of energy boarded, enlarged the range of convenience some constructs and passed to use new constructs, which corresponded to a less fragmented and more significant learning in relation to the concept of energy.
