This cutting edge volume explores holistic trends in multilingualism, analysing the processes of both 'becoming multilingual' and 'being multilingual'. Multilingualism has increased in recent years due to globalisation, transnational mobility and the spread of Information and Communications Technology (ICT). This volume explores some of the trends in the study of multilingual education by putting together research studies that analyse the processes of both 'becoming multilingual' and 'being multilingual' in educational contexts.
