"The Advantage of Diversity"Over the last few years, our school staff have been working on our school's European development plan, which has introduced new innovative subjects and activities at our school and advanced internationalisation in many different fields. Intercultural education is one of the key aspects in our daily work, as one can see from the many different languages taught at our school and our numerous international activities and projects (exchanges, language and study travel, international language certificates, bilingual classes, one international class, ...). Preparing our students for an international working environment in today's globalized society is our ultimate goal. We have thus recently introduced CLIL into our schedule and we are busy building a network of partner companies in our European twin towns to be able to offer our students international internships on a regular basis. Our next goal is to introduce and implement the "International Baccalaureate" (IB) at our school, an internationally recognised bilingual school leaving exam (A-Levels).In order to further develop our European school development plan "The Advantage of Diversity" we need to train the staff involved in the numerous new international projects at our school. Evaluations among teachers and students have identified the need for training in the following fields:- intercultural training of exchange students, international student interns and colleagues - preparation of students for an international working environment- foreign language training of the teaching staff (methodology, pedagogy and language brush up)- social and cultural training of teachers to enable them to teach students the European dimension of subjects like social studies, history, music and arts- bilingual teaching of subjects like geography, maths, sciences or PE- how to deal with international, and thus very heterogenous, student groups- how to contact new European partner institutions (via eTwinning)- and especially how to prepare students for the International Baccalaureate and how to teach the contents of the IB that are new to usAfter the training our teachers will cascade their newly acquired knowledge down to all the colleagues involved in the various projects. There are currently about 200 teachers and 2350 students at our school that will benefit from the training to a greater or lesser extent.The success of intercultural competence can not only be measured with hard facts, such as student's achievements, but also with soft criteria, such as student's identification with the school and teacher's job satisfaction.Our vision for the near future is to go international, to modernize and to open up our school to Europe even more. In order to achieve this goal, we will integrate the competences and experiences acquired by staff participating in this project into our strategic European school development plan. Another focus in the following years is likely to be the topic "healthy school", but before concentrating on this new area, we are keen on improving our skills and abilities in our current development plan concerning the internationalisation of our school!
