In this paper, we will first illustrate similarities and differences between teaching strategies used in regular English lessons and in bilingual programmes. Then we will summarize the results of studies examining questions that teachers, parents and school administrators are often concerned about. These questions include the following: Do pupils in bilingual programmes show deficits in the development of their native language or in the development of subject knowledge? Are bilingual programmes also suitable for children from migrant backgrounds and for children who are at risk of poor academic achievement? Finally, we will discuss how children who attended a bilingual programme in primary school can be supported in secondary school.engbilingual educationprimary schoolL1 acquisitionL2/foreign language acquisitionsubject content370bookpart
