This book chapter presents the results of a case study conducted by Pompeu Fabra University with young people aged between 16 and 18 years who worked together on the creation of audiovisual pieces at workshops run in accordance with the participatory audiovisual methodology, a combination of alternative audiovisual approaches and the postulates of educational commons. The case study was carried out in two rounds at a non-formal education association in the Raval neighbourhood (Barcelona). The results show how these adolescents deal with the commoners role and how commoning practices emerge in the group. They also revealed how their media skills were improved, showing progress from instrumental to more reflexive use. Finally, we analyse how this reflection and creation process promotes the generation of spaces for action and offers the participants a platform on which to get their opinions heard.
