During the teaching of a subject, engineering in this particular case, students acquire knowledge through different learning activities that are guided by the teaching staff. In this process, students work with the resources and activities provided by the faculty, acquiring knowledge and demonstrating it through an exam. In this work, students have been asked to share their learning experience and to create knowledge resources that can facilitate learning. Thus, collective knowledge has been created in the subject, which can be used by anyone. The work has shown that students can create useful knowledge for the subject, as well as establish an ontological classification of all the knowledge necessary for learning the subject. The results of this analysis show the ontology defined by the students that is applicable to any subject. This study also describes the process carried out for the creation and management of knowledge by the students themselves, as well as the perception of the use of the collective knowledge created.
