The GeoGebra apps are presented here to give a constructivist learning and an academic motivation, for the engineering students in the differential equations course of the Universidad de Antofagasta, Chile. These apps are relevant, so for they could see the solutions of differential equations with separable variables, giving a different approach than the traditional one with a better understanding. This dynamic geometry software, called GeoGebra, was chosen for the creation of the applets, due to its free access and its dynamism with which Many authors have shown the great advantage of using this program, to carry out mathematics classes regardless of the level student.
