Linguistic Diversity on the EMI Campus presents an in-depth ethnographic case study of the language policies and practices of universities in nine countries around the world. Each chapter provides a detailed presentation of the findings from that university, considering the presence of linguistic diversity in institutions from Australia, China, Finland, UK, Turkey, Malaysia, Italy, Spain, and Japan. Split into three parts, these nine case studies demonstrate the extent to which international-oriented institutions can learn from each other’s practices and improve their language policies. Linguistic Diversity on the EMI Campus is vital reading for students and scholars working in the fields of applied linguistics, multilingualism, and education.
