Estudo sobre a teoria de Ginzburg-Landau e o conhecimento de mapas conceituais

Abstract

The objective of this work is to present a proposal for a theoretical analysis of the theory of superconductivity together with an analysis of the Ginzburg-Landau equations in this context, in which the superconducting state is characterized by an order parameter, given by constructing a wave function Ψ (r, t) to describe the quantum behavior of particles and to show the knowledge of concept maps as a didactics tool. We will present the theoretical aspects of the phenomenon of superconductivity and its applications, and examples of conceptual maps including some models containing concepts of superconductivity. The specific objective is to use the maps as a conceptual study of physics theory in the academic, they are methodological tools to help in understanding the concepts with the interpretations, through hierarchical diagrams, shown in a conceptual framework. The research methods adopted are the development of the Ginzburg-Landau equations, the research that includes students enrolled in undergraduate courses in Physics, as individual basis and for last the implementation of a short course, with the participation of undergraduate and graduate students in physics and related areas, distributed in groups or individually to analyze the results. The survey instrument adopted for the last two methods, in order to obtain the scores for the students performance, will be a simple questionnaire, using pencil, black ballpoint pen and A4 paper, containing eleven questions in the first method and in the second method (short course) it will be ten conceptual questions (open or closed) about the concepts related to the topics provided by the instructor and finally it will be presented the analyzes of the results.
