This edited volume presents eleven empirical papers reporting the existing literature and the results of an original study focusing on EMI (English as a medium of instruction) in a particular area (Central and Eastern Europe, Western and Southern Europe, Nordic/Baltic countries, Central Asia, the Middle East, East Asia, South-East Asia, North Africa, Sub-Saharan Africa, South Asia, and Latin America). Each of these different areas tends to have its own ways of dealing with the EMI issue, and these are brought together in a meta-analysis in the final chapter. Implications for the conduct of English as a medium of instruction are drawn, both on a chapter-by-chapter basis and also in the meta-analysis. The examination of EMI on a contextual basis is a unique feature of this book, setting it apart from others in the field, which almost all deal with a single or limited context. The volume will be of interest to policymakers, institutional heads, graduate students and their teachers, and to thesis writers and researchers.
