The field of applied linguistics covers a diverse range of research and practice, and has developed somewhat differently in various parts of the world due to variations in local socio-cultural conditions, needs and issues. However, this local diversity does not reflect a field that is incoherent, but rather one which has a broad, shared international agenda which is invigorated by the diversity brought to the field by local perspectives. The papers in this volume represent some of the major global directions that research in applied linguistics is taking and shed light on how language is used to affect practice.The aim of this volume is to explore some of the key methods and issues which are guiding applied linguistics into the future through an examination of these issues in local contexts, thereby providing a basis for understanding the global directions the field is taking. These directions follow two historically defined paths: those related to educational studies and language teaching, and those related to social issues involving language. In the volume, half the papers focus on the former, examining issues of language teaching, language teacher education and second language acquisition, while the other half examine social issues related to language use, bilingualism and multilingualism, and language policy and planning. The collection of papers presented in this book illustrates how these traditional themes are influenced by the rising forces of globalisation and the use of technology, thus exemplifying both the new and old ways in which the study of language is realised.
