"SD apoyada en el uso de la app Electric Circuit Studio® y aprendizaje activo como mediadora para la comprensión del voltaje AC y DC en un circuito rectificador de onda completa"

Abstract

This project consists of presenting the design, validation, implementation and evaluation of the didactic sequence (SD) entitled "Route of the electric current: from the wall to your cell phone", mainly supported by 3 elements: (1) learning active as a pedagogical-didactic aspect, (2) the use of ICT, especially the APP Electric Circuit Studio® in the technical-technological aspect and (3) the understanding of the transformation process of voltage and current in a full-wave rectifier circuit in the disciplinary aspect (physics). The SD was implemented in middle-rural education students in Pitalito (Huila) without internet access, respectively characterized population. The design and validation process of the didactic sequence is based on complementary statements with the Aiken index. The methodology for the implementation and evaluation of the SD is a pre-experiment type with a pre-test / post-test / post-test design and a mixed analysis that has quantitative elements such as the calculation of the Hake gain, the Bao and Redish concentration factor and the Student's t test, in addition to qualitative elements such as the semi-structured interview based on eliciting situations. The results show a statistically significant gain in learning with a higher concentration in a single correct model. By way of conclusion, it can be stated that the didactic sequence contributes to the meaningful learning of the students in relation to the topics addressed.
