espanolEste trabajo presenta los resultados de la estrategia pedagogica fundamentada en La Construccion de Prototipos (LCP) y el Aprendizaje Basado en Proyectos (ApBP) que fue aplicada en cursos de Electricidad y Magnetismo para estudiantes de ingenieria de dos universidades en Bogota-Colombia. Este articulo se enfoca en tres tematicas: Electroscopio, Balanza de Torsion y Generador de Van de Graff. El trabajo presenta fortalezas y dificultades de la estrategia empleada en comparacion con la instruccion tradicional. EnglishThis paper presents the results of the teaching strategy based in The Construction of Prototypes (TCP) and Project Based Learning (PrBL) which was applied in a course of electricity and magnetism for engineering students of two universities in Bogota-Colombia. This research has been focused on developing three projects, namely: electroscope, Torsion Balance Coulomb, Van de Graff generator. We present our Analysis result obtained using psychometric tools such as Hake gain. In addition, the strengths and difficulties of the strategy employed compared to traditional instruction are presented.
