Utilización de la Transformada de Laplace como herramienta metodológica en el análisis de circuitos eléctricos

Abstract

The research aimed to demonstrate the impact that has the use of the Laplace Transform as a methodological tool in improving the academic performance of students in the sixth semester of the School of Automotive Engineering, in the analysis of electrical circuits. Scientific, inductive, analytical, synthetic and longitudinal method was used. In the work groups of students enrolled in academic periods were considered: - August 2014 and October 2014 - March February 2015, taking the arithmetic mean of the academic performance of students before and after using the Laplace Transform in the corresponding periods. To validate the hypothesis, we applied the statistical "z" normalized to the contrast of equal means of normal populations with a significance level of 5%, which shows the area of risk for rejection of the null hypothesis and accept the research hypothesis, associated with zt = 1.64. We apply the equation equal means contrast with the statistical data obtained from each group, acquiring a value zc = 4.41, which is greater than zt, which rejects the null hypothesis and accept the research hypothesis, showing that the use Laplace Transform as a methodological tool works positively, improving the academic performance of students in the analysis of electrical circuits by 21.9%, so it is wise to continue with the proposal to raise the percentage.
