Germany has been a country of immigration for decades. Language support for immigrants is therefore not a new topic. However, massively increasing numbers of refugees reveal the gaps and challenges of the German education system in this area in particular. In schools, the area of ​​German as a second language (DaZ) - and in particular language support - is particularly affected. This is precisely where this volume comes in. In addition to an overview of existing language support concepts, it offers promising ideas and concrete suggestions for improving the support offered. The authors show how intensive classes work, how needs can be sensibly determined and synergy effects used, and what opportunities the multi-collectivity approach offers. In doing so, they take both the perspective of the teachers and that of the students. The stated aim is to improve the urgently needed systematic language support in DaZ lessons.
