The Geschwister-Scholl-Schule in Solingen is a secondary school having six classes each year. Due to its size the school operates in two different buildings - the classes 5 to 7 learn in another building than the classes 8 to 10, which share a building with our A level students. Formally, the school is a "Gesamtschule", which means that students can get different qualifications at the end of year 10. We offer lower qualifications but also give our students the possibility to take their A levels at our school. Since 2009 the school is a full-time school - apart from offering students a formal education, we engage in social projects to make our students responsible members of society and we also have a cultural focus. To give an example, our students can choose between different kinds of classes like string- or vocal singing classes depending on their own interests and talents. In 2009 the school was therefore awarded with the "Gütesiegel individuelle Förderung" (a certicate for successful individual promotion) by the ministry of education in North Rhine-Westphalia and we recently received a certificate for being a school motivating and supporting pupils in their choice of profession or apprenticeship (Siegel "Berufswahl- und ausbildungsfreundliche Schule").Due to the world becoming more and more connected, a profound or even excellent command of the English language is a must have in both the work- and the private life of our students. However, this is something that common English lessons at school won't be able to bring on, so the school decided to establish an optional bilingual branch in 2014. Learners who choose the bilingual branch have extra lessons in English in the first two years, which are supposed to enhance their knowledge and competences. Starting in year 7, the pupils will have biology as their first bilingual subject. In year 8, gym classes or physical education will also be taught bilingually. At the moment our teaching staff consists of 120 colleagues, including two colleagues who already have a teaching qualification for English and biology and two colleagues who have the qualification for English and sports. All of them are members of working group called "bilingual classes", which develops concepts for bilingual lessons. Further members either have a qualification for English or a qualification for biology and/or sports. Some of our colleagues have already made first experiences with bilingual lessons by teaching small units bilingually. These experiences have been discussed and are currently being used in the extra lessons in years 5 and 6. To muster the increasing number of bilingual students in the coming years, interested teachers will need a professional teacher training concerning the various methods required in bilingual lessons (Biology and P.E.) and, additionally, would like to sit in on P.E. classes at British schools. An important issue at our school is teacher trainings in order to improve teaching competences.We are sure that all members of the working group “Bilingual Classes” will profit from the methods and training material that the two participants will bring back from the CLIL Teacher Training since the chosen CLIL Teacher Training programs will take place at different institutes and pass on the basics of CLIL classes, different teaching methods and different fields of application. On one hand, our participants will enhance their linguistic competences as well as increase the exchange between european partners. This will lead to highly qualified and motivated bilingual classes given by highly qualified teachers who have a wide range of teaching methods at their disposal.We think that bilingual P.E. classes will focus on communicating skills. Therefore two P.E. teachers would like to sit in on P.E. classes of two different English partner schools (secondary school and college). The different experiences at these different schooltypes will enhance the communicative skills of our teachers in P. E. and will increase the quality of our bilingual classes, as they will work with a very heterogeneous studentship. We are sure that all partcipants will pass on their insights to all members of the working group, integrate their insights into their own Bilingual P.E. classes and make them livelier, hence.The teacher training programs are a strategic instrument in order to develop and internationalize the Geschwister-Scholl School and will help us to increase the number of qualified staff able to teach bilingual lessons in Biology and P.E. and to establish a methodical basis that can be further developed in the coming years. We intend to use all contacts beyond the projectplan resulting from the teacher trainings for more international exchange programs (maybe at one of the English partner schools) especially for students and teachers of the bilingual courses. Additionally, our school will generate a more international profile.
