Teaching economy in colombian universities is so difficult, specially in curriculums for students of fields different to economy, in which economy courses are often so little motivating, and there are developed with a very specialized terminology, difficult to be well understood; in addition to that, there are big troubles in testing in real world whether student's ideas to control an economic system are effective or not. Computer science offers new tools in all human activities, including education. Here it is presented HICEFE (Computational tool for Comprehension and Experimentation with Economic Phenomenon) that is a proposal to incorporate computational technology in teaching economy, and to reinforce the application of a systemic approach in the educational process, feasible of being used in different study fields. Models that conform the tool have been made with Systems Dynamics methodology, to be presented like microworlds that offer to the user the opportunity to study economic phenomenon, evaluating the student's understanding by experimenting with stimulated solutions to problems.
