Proposta Metodológica de Inserção de Algumas Aplicações Práticas do Campo Magnético na Técnica, no Processo de Ensino Aprendizagem da Física na 12ª Classe

Abstract

The various phenomena that occur in nature, among them the electromagnetic phenomenon, is responsible for numerous inventions today. Thus, in the unfolding of the Teaching-Learning Process of Physics, there are several questions that have been raised by researchers about the electromagnetic phenomenon, this work has as a scientific investigation problem: how to insert some practical applications of the magnetic field in the technique, to to improve the Teaching-Learning Process of Physics, in the 12th grade of the Machines and Engines course, at the Instituto Politécnico da Humpata? Because it constitutes the objective of investigation: to elaborate a methodological proposal of insertion of some practical applications of the magnetic field in the technique, to improve the PEA of Physics in the mentioned class and school. In order to fulfill the objective, the following research tasks are required: To provide theoretical foundations on the importance of practical applications of Physics in the generation of new technologies and to present the theoretical basis for inserting some practical applications of the magnetic field in the technique of teaching Physics in terms of the exit profile and professional activity of the students; diagnose the current state of the PEA of Physics in the 12th grade, at the Instituto Politécnico da Humpata; elaborate a methodological proposal for the insertion of some practical applications of the magnetic field in the technique, to improve the PEA of Physics in the 12th grade, at the Instituto Politécnico da Humpata and resorted to the following research methods: theoretical (analysis-synthesis, historical-logical induction and deduction), empirical (document analysis and questionnaire survey) and finally the statistical method. The results of the surveys to teachers and students showed that it is necessary to insert some practical applications of the magnetic field in the PEA of Physics. The methodological stages (planning, guidance and control) can contribute to improving the PEA in Physics, within the framework of some practical applications of the magnetic field in the technique.
