"In the project ""Big problems go mini"", about 20 students (SuS) each from Silverberg-Gymnasium in Bedburg, from IES Joaquin Rodrigo in Madrid and from St. St. Kyril and Metodiy School in Velingrad, Bulgaria, are dealing with problems and challenges of our time. In order to provide a holistic approach to the SuS and to activate and motivate them, the young people, aged about 14-18 years, develop several short plays. The choice of 5-15 minute performances in limited space, e.g. classrooms, allows for a more intimate setting with an audience limited to a relatively small number of spectators.The background to the idea for this project was the discussions following the visit to the Microtheatre at our last meeting in Madrid. The SuS developed the idea of using a similar approach in a new project as a method to illuminate a common topical issue from different national perspectives and to suggest common solution strategies from a European perspective.The aim of the project is to identify one's own concern in dealing with global problems and to develop individual competence to act in one's personal environment.For this purpose, the implementation of the so-called ""mini theatre"" in the classroom (MTK) is planned. The SuS should create short plays of 10-15 minutes in international small groups about socio-cultural/economic/political problems, which will be performed at the meetings. The plays contain short episodes of everyday life, which are known to all spectators and whose backgrounds are otherwise all too easily overlooked or dismissed as unchangeable. The SuS can write short scenes in which they are ""accidentally"" confronted with one of the topics and thus talk about the problem from their national perspective. Example: Young people meet at a bus stop, see a beggar or homeless person, talk about economic problems, poverty/wealth or common/different developments in their own countries. Other possible topics include violence at school, violence in families, war and flight, income levels, inequality, gender equality, racism, discrimination, fanaticism, different educational opportunities, democratic values, participation in politics, position and reputation of the individual in society, media consumption and criticism. These topics affect everyone and are therefore of interest to a broad audience.The given thematic framework for each of the 4 phases and meetings is the basis for a regular project work. Thus the young people deal with cultural differences and points of friction in the first part, socio-economic problems in the second part, political issues in the third and aspects of sustainability in the last phase. The common element of the activities is the elaboration and performance of the plays with subsequent feedback from the audience. Discussions about the content of the plays are directly connected. For each thematic focus, a methodological focus is also chosen in the preparation (Phase 1: research and narrative interviews, Phase 2: data collection and analysis, Phase 3: interviews and expert discussions, Phase 4: media presentation including feedback). The results will be available for presentations in selected specialist teaching sequences (possibly supported by project participants as ""experts"") as well as in the form of working documentations accompanying the performances of the plays. Since work results have to be continuously adapted and exchanged, it is necessary to use interactive forms of cooperation and communication (such as padlet, homepage etc.). A review of the achievement of objectives is given on several levels. As feedback after the plays by using a digital platform (Edkimo), by discussions and observations during the work phases and the mobilities, by the presentations of the research and work results.The SuS benefit from this project on various levels. Their intercultural, linguistic, emotional and media skills are promoted. They develop an awareness of their own role in the social and political environment and recognise opportunities to influence situations positively, even on a small scale. The Mini-Theater contributes to all these developments in a concrete form. The young people overcome inhibitions in private and public situations through the change of perspective within the theatre work and the associated personality development. In this way, they gain self-confidence and can share their experiences with others based on sound background knowledge, and express their opinions in a well-founded way."
