"In times of decreasing cohesion and solidarity between European countries and regions it was getting more and more important to be in contact, look for the needs and opportunities of the others and work together. We enabled this for pupils, teachers and stakeholder of this project. Seven Schools of General Education with secondary level from 6 countries worked together in workshops, national and transnational meetings, to be able to create radioclips and results with intellectual outputs provided at the internet.""Sound of Europe - we are making radio"" allowed us to create radioclips and emissions about common themes together.This gave us the opportunity of learning and teaching in an amusing touch, new ways and open frame, related to the needs of the participants. Bringing outputs like a community where it´s possible to share ideas, reflexions, stories and poems, sounds and music of different countries and regions were a tool for more cooperation. Regional and European themes like sounds of our school, sounds of our region, interviews, stories and music, apps to use for tourism and traveller-information, situation and development of the migration in the different regions in a European context or other relevant European discussions have been held at schools and with stakeholders and on social- and other media.But beyond that we opened the way to reach more people with the ideas and outcomes of this common work. Pupils should have become more open-minded, should be enabled to work in international groups in an other language than their mother-tongue and be happy to create something very new to share with others. Teachers should have learned more about the transnational aspect of teaching and learning, had the opportunity to increase their English and their capacity to work in teams. Schools offered more international aspects to parents and pupils. Local authorities were able to present their special culture, surroundings, could enjoy the outcomes of the project and use it for touristic, social, economic and youth-policy objects. Regional and national/international radio-enterprises can cooperate and the founding of an european radio-station for pupils should have been one possible target of this project - but this goal was reached. Therefore, it can only be carried out transnationally! We worked on the topic of making radio and working on national stereotypes at the beginning due to the cross-disciplinary quality of the above topic, which allowed integrating it in many areas, we could deal with other subtopics such as music or tourism in each of the cities participating in the project. European citizenship versus national identity, creativity and culture through radio.In order to realize our project, we meaned to apply a ""learning by doing"" way of teaching. The creation of a radioclip allowed the students to apply their technological knowledge and to have a feedback of it. The students were the main protagonists of an active cognitive way based on research-action processes finalized to produce improving changes in the learning process. Brainstorming, problem solving, simulation, peer education have been at the base of a new inclusive methodological approach in which knowledge is a social process which comes out from the constant relationship with others. The students useed different sources to gather data and obtain relevant information; they planed the activities, valued the outcomes, and proposed creative and alternative solutions. The results assessments and transmission of the work to the other groups happened through our virtual platforms, which will help to be aware about the use of the digital. The teachers guided all the phases of this learning process, having a leading role in flipped classroom activities and used experiment innovative learning methods which were shared with the work group."
