| Abstract: | English connects all areas of science around the world. Productive and receptive English-language skills are thus a crucial tool that schools must provide their students with in order to prepare them for higher education and professional life. The introduction of bilingual instruction of subject matter, often referred to as Content and Language Integrated Learning (CLIL), allows for incorporating English as a medium of communication directly into the science classroom. However, such bilingual lessons are often only accessible in the context of bilingual programmes for which students have to qualify based on their previous performance. The present study assessed the applicability of bilingual modules in non-selected groups of students. For this, a bilingual teaching unit on immunology was developed and implemented in standard German ninth grade classes. After the unit, bilingually taught students showed the same content knowledge gains as their peers who had been taught solely in their native language. Average achievement motivation ratings before and after the unit were medium to high in all classes, and the majority of students was open to more bilingual lessons. An evaluation of student comments provides further indications for the development of future bilingual units. |
