Book excerpt: This edited book examines English-Medium Instruction (EMI) language policy and practice in higher education around the world, highlighting how English language usage affects the internationalization of universities, the way that disciplines are taught and learned, and questioning whether internationalization through EMI achieves the values of global citizenship and inclusivity/diversity to which it aspires. Written by experts in the field, the book includes data-based research from universities around the globe, with three chapters on Asia and the Far East (Malaysia, Japan and China), four on Europe (Denmark, the Netherlands and Italy) and one each on Africa (Ethiopia) and Central America (Mexico). Sources include policy documents, questionnaire surveys, focus groups and semi-structured interviews involving university policymakers, lecturers, students, and administrative staff. This book will be of interest to students and scholars of language and education policy, internationalization and applied linguistics, particularly English-Medium Instruction (EMI), academic English and English as a Lingua Franca (ELF).
