A inserção da termoeletricidade no Ensino Médio: Uma alternativa metodológica a partir do ensino de geradores elétricos

Abstract

Thermoelectricity is an area of physics that deals with the direct transformation of thermal energy into electrical energy and the transformation of electric energy into thermal energy. The theme developed in this work, insertion of thermoelectricity, represents the basis for the elaboration of an educational product and is related to the study of electric generators. The central idea is to introduce the phenomenon of Thermoelectricity in the study of Electrodynamics, classes of high school, explored as a didactic transposition for the teaching of electric generators. The proposal is based on the elaboration of a didactic sequence related to the three pedagogical moments of Delizoicov and Angotti (1994), in which we have a moment of initial problematization, through text and questionings on the subject, a moment of the formal presentation of the curricular content and a moment of the presentation of the Thermoelectricity through the construction of an experimental apparatus, so that the thermoelectricity thematic allows an alternative to the understanding of the electric generators, as well as the process of transformation of energy.
