The applicant of this project, a private secondary school, aims to improve and promote the quality of language education at school in both classical foreign language teaching and in bilingual teaching as well. Specifical for this school with its main focuses on languages and natural science is a high percentage of students with non-German mother tongue. Therefore there are special challenges that language teachers have to face in their teaching. Within the framework of this project (whitch should be a continuation of the correspondent project iof the previous year) a language teacher will be sent to attend a "Methodology"- course and two natural science teacher will be sent to attend CLIL courses (Content and Language Integrated Learning). The three courses will take place in an international context, where teaching approaches outside German-speaking countries will be conveyed. The aim of participating these courses is on one hand the improvement of teacher´s qualification and thus quality assurance (and improvement) of education. On the other hand the acquired know-how should be forwarded via presentations and possible follow-ups to the rest of the staff. Finally long-term advantages as well as additional values of the project shall be evaluated in the context of regular school-internal evaluation of teaching.
