Discrete Mathematics teaching-learning processes are an area where significant learning is most difficult, then the use of novel methodological strategies is necessary. This work relates the process of collaborative creation of a wiki for a specific topic of Discrete Mathematics, process developed by students and monitored by the teacher. The main purpose was to evaluate the use of wiki as an educational resource to promote learning and the development of generic competencies. Students were evaluated before and a survey was administered to collect their perception of it. The results show that the development of the wiki had positive results: increase in qualifications, development of teamwork competency and other generic competencies, it was also possible to modify the role of the teacher and the interactions between students. In addition, it is concluded that both the activity and the methodology used can be an input for processes to improve educational quality.
