This paper presents the first results of the innovation and educational improvement project FUSIONA, which combines the transversal learning of German as a foreign language (GFL), the interdisciplinary learning, the cultural and scientific-technical heritage protection and its social dissemination. The principal objectives of this service-learning project are, on one side, to redesign a practical task of the course of GFL and, on the other side, to spread the cultural heritage of the four museums of the (name of the University). Transversal skills, like effective communication, teamwork or social and environmental commitment are enhanced, and collaborative learning is put into practice by the design and edition process of informational videos. Thereby, GFL and Audiovisual Media students and teachers work together in order to create and evaluate the outputs. The currently quantitative and qualitative results show that interdisciplinarity is also feasible when language learning, media technique and culture join together.
