Abstract:

The following research has the goal to develop an educative software for the teaching-learning of the reduction method in the salvation of lineal equations’ systems. It’s framed in the form of feasible project and it’s developed in three steps, the first one is the diagnosis and it allows us to get information about the actual situation in the 3rd grade of High school in the “Escuela Técnica Industrial Laudelino Mejías”, in Trujillo, Venezuela, six teachers and twenty students of 3rd grade are the sample of this research. The second step corresponds to the software design RYDUX, and in the last step is when it’s evaluated the aspects of the interface, like psychological, aesthetic and technical aspects with experts of the already mentioned group. The used techniques and instruments were the interview, the questionnaire and the participating observation. It’s concluded that it’s necessary to make some changes that innovates the used strategies and resources to impart the topic that is studied. We hope that the results of our research allow using this tool as support in the classes.
