Web 2.0 has generated a change in people’s attitudes ranging from static to dynamic thanks to the web tools that allow users to share, collaborate and participate, generating contents in a cooperative way. This research aims to identify whether the Wiki tool is suitable for contents creation, both theoretical and practical, following the philosophy of cooperative groups, in students enrolled in the Master's Degree in Teacher Training in Compulsory Secondary and Upper Secondary School Education, Vocational Training and Language Teaching in the Campus of Ceuta (n = 73). The method is descriptive and correlational, carrying out an analysis from a mixed approach (quantitative and qualitative). Two instruments were created to obtain the data: a questionnaire to evaluate the Wiki application as a valid tool for the teaching-learning process (post); and a debate outline for the discussion groups consisting of eight groups of 8 members, except one formed by 9. The quantitative results showed the application favoured the class group participation, the inquiry, collaboration and learning and in fact it offers new perspectives for the teaching process. The lack of time to properly develop the activity stands out as a negative aspect. At a qualitative level the results showed that students were reluctant to apply a new educational methodology, but as the classes progressed, they valued the action positively, considering the possibility of applying them when they were teachers. As an improvement proposal they suggested to create smaller groups to produce contents through the Wiki. We can conclude the Wiki application can be a valid tool for contents creation, as long as it is applied in smaller groups.
