To take advantage of the numerous new resources for teaching/learning provided by the Internet, teachers should understand technologies that normally are not part of their fields. To get around this, they can use the AulaNet environment, which manages the learners' navigation through the educational content and offers integrated communication, coordination and cooperation services that can be used in the course. In this paper we report about how the AulaNet was configured and how its services aid in the creation and application of a course wholly taught through the Internet. We also show the methodology used as an attempt to get the students to learn on a cooperative basis, reporting the problems, the positive points and the results encountered during the six editions of the course.
