Higher education institutions (HEIs) are increasingly affected by globalization and internationalization, with implications for language use, teaching and learning in their academic communities. As a consequence, HEIs may change their approach to multilingualism on campus, taking into account language needs as well as opportunities and challenges associated with language diversity. The book aims at discussing aspects for the design of language policies, which could support internationalization and promote multilingualism and participation of different stakeholders. By presenting a language policy model, the book provides an alternative for those engaged in language diversity in HEIs.
