The model of English that should be used in classrooms has long been a subject of debate. World Englishes, Implications for International Communication and English Language Teaching, describes varieties of World Englishes and discusses the advantages and disadvantages of selecting a particular variety from the point of view of both teachers and learners. It aims to examine and re-evaluate concepts such as 'standard', 'variety', 'native speaker' and 'non-native speaker', and to validate the role played by multilingual and multicultural English language teachers, arguing that context and learner needs should determine the variety to be taught.
