The book focuses on the pains and gains of international mobility in teacher education – its challenges and benefits. The aim is on the one hand to identify some of the challenges which help to explain the low percentage of internationally orientated teacher education students and suggest how to overcome them. On the other hand, major benefits of international mobility in teacher education are presented in the form of competences that can be acquired through studying and teaching abroad. The five chapters of this book refer to reports on practical experiences with international mobility in teacher education at different institutions. The authors outline problems, challenges and advantages, as well as present empirical studies on the international mobility of teachers. The target audience are persons organizing mobility programmes or educators working with international students and researchers in this field. This book aims to contribute to the promotion of international student teacher mobility and to give suggestions on how to implement and optimize such programmes.
