Objetos de aprendizagem para ensino de circuitos elétricos em regime estacionário com o uso de números complexos em um curso de engenharia elétrica

Abstract

The introduction to the teaching and learning process has worried many professionals in the most various educational areas, who try to find different alternatives to overcome difficulties, mainly in class. The real understanding of the relation among the electrical quantities is determinative for the development of a professional and this is exactly the purpose of the use of the resources, stimulating the significant learning and enhancing the methods of analysis. The Learning Objects, with thenecessary adjustments, are used as support to the construction of mathematical concepts related to the analysis of circuits under stationary regime, which, for involving electrical quantities, such as tension and electrical current, require the solution of sinus and cosinus equations, which are not always easy to be solved. The present work is based on the theory about Registration of Semiotic Representation, by Raymong Duval, specifically about the semiotic and cognitive organization of the graphic representations.
