In times of globalisation, more and more lecturers with other first languages than English have to – or would like to – give lectures, seminars, and presentations in English. This book discusses issues that need attention when individuals and institutions switch to English-medium teaching in higher education, and it provides the tools to put insight into practice right away. With its combination of reflexive and hands-on approaches, the book equips and encourages readers for the adventure of English-medium teaching from which teaching staff, students, and institutions will profit.
