Análise do uso de um texto didático sobre o conceito de calor numa abordagem Kellyana

Abstract

In order to help physics teachers who face the new curricular proposal introduced by the National Curricular Parameters for high schools, this work has the objective to evaluate whether the texts “Leituras de Física”, produced by the Physics Teaching Reelaboration Group, from the Physics Institute of São Paulo University, allow the development of some competences related to the concept of heat. In this study, we also research the application of kellyan experience cycle (anticipation, investment, encounter, confirmation/disconfirmation, constructive revision), using this material, to high school students, during thirty classes of fifty minutes each, in which the two first involved the anticipation phase. After the interventions, we applied the post-test, with two intentions: to allow the student to make a great constructive revision and to diagnose if the student had developed the expected competences. The comparison of results obtained in pre-test, in interventions and post-test showed that this didactic resource, used in a experience cycle, contributed not only to the development of specific competences related to the concept of heat, as well permitted that the students could progress in their capacity to read and write texts. Therefore, the methodology applied in this research, besides familiarizing the participants with the specific language of physics, allowed them to develop the necessary competences to analyze scientific news.
