World Englishes
Whereas the English-speaking world was formerly perceived as a hierarchy of parent (Britain) and children (’the colonies’), it is now seen rather as a family of varieties. The English of England, the original source of all the World Englishes, is now seen as one of the ‘family’ of world English varieties, with its own peculiarities and its own distinctive vocabulary.
I just discovered, via a LanguageHat post on Singlish, that Wikipedia has a wonderful index of all the major varieties of English (they use the term “dialects” which I have a problem with, since some of these varieties are not mutually intelligible).

While Wikipedia reflects the reality of communicative English, the version perpetuated by commercialized education in East Asia is quite different. Unlike Western nations, Asian governments have not been able to hand education over to professionalized educators. Subsequently, fully modernized interpretations of disciplines have not been transmitted to students, parents, and other interested parties.
