"<< Objectives >>The project ""Message in a Bottle - You are next!"" aims directly at supporting professional and voluntary staff in youth work - in art-oriented environments - to enable them to provide young people with engaging and innovative activities. Together we want to develop two hybrid forms of cooperation, collaboration and exchange:A shared storytelling method named ""message in a bottle"" and a hybrid gameplay called ""secret world"" that combines physical, analogue elements with virtual objects.<< Implementation >>The central activities of our project will be two ""future labs"", where independent groups of young people from Spain and Germany working together on two game-based learning/training formats. Creativity and exchange are the central elements of these activities.Besides necessary coordination and project management, we also plan to implement a joint staff training on the foundation of game-based learning and open-source augmented reality (AR).<< Results >>Our project will develop innovative learning/training environments for ""digital natives"" in the age group of 13-21 years. Two game-based creative activities will provide opportunities as well as needs for transnational cooperation. Our participants will learn to work creatively in a team and compete virtually with members of the same age group from a different country.Youth workers will acquire the skills necessary for guiding these creative activities."
