Evolução dos modelos atômicos: uma proposta epistemológica na elaboração de modelos teóricos para explicar a estrutura da matéria

Abstract

This study deals about the teaching proposal that aims to teach the main of atomic models through an epistemological perspective, in order to lead the student to understand that the scientific doing is a human construction, product of the dialectical historical process subject to the most varied contradictions. For that, it was of great importance the valuation of the previous knowledge of the students in the elaboration of a Potentially Meaningful Teaching Unit (PMTU), under the guidance of Marco A. Moreira. As well as the progressive differentiation of concepts and ideas in the context of the History of Science through the view of Thomas Kuhn, which describes scientific evolution from the paradigmatic revolutions. In general terms, everything turns clear that any support for the development of didactic tools that is going to aid in teaching practice is a valid effort, because in the face of the results, we can infer that the pedagogical product has succeeded in its purpose, based on the theoretical assumption of meaningful learning of Ausubel, was able to promote significant improvements in the apprehension of concepts and meanings, as well as to increase students' capacity for argumentation in the face of problem situations at more complex levels.
