Proposta de atividades experimentais para o ensino de potência elétrica em aparelhos resistivos

Abstract

The central objective of this work is to present an inquiry-based teaching sequence that addresses the electrical power of resistive circuits in an innovative way, encouraging students' critical thinking and argumentative skills. This topic was chosen because most educational materials addressing such content do so superficially, with little or no suggestion of practical activities, prioritizing the memorization of formulas over a real understanding of the involved physical concepts. Therefore, in order to promote active and engaged participation from students, the inquiry-based teaching sequence was structured based on the POE methodology, which is grounded in the prediction, observation, and explanation of certain phenomena. For this purpose, three experimental activities were used, two of which were original, along with a computer simulator and a sequence of investigative questions. The experiments proved to be attractive in capturing students' attention, as they showed willingness to participate and interact throughout the classes. The responses given by them during the application of the inquiry-based teaching sequence were analyzed and grouped according to the presented structural similarities. Based on the results obtained, it was possible to conclude that this work serves as an effective tool in constructing scientific knowledge and redefining misconceptions presented by students about resistive circuits.
