“Teaching English as World Language” is a book that is deeply rooted in the principle that English teachers or teachers of other languages should reassess their perceptions towards the language they teach. They must be aware that the unintentional recycling of some common terms associated with English teaching, such as “foreign” as in “foreign language” or “secondary” as in “second language” may lead to the isolation of learners from the very language they try to learn. It is this principle that inspires this book to emerge as a new breed among its kinds. Its uniqueness lies in its author’s deep understanding of how languages are learned and acquired. There no doubt, this book should be the right choice for teachers who seek to prepare their students for the whole new world within which they can easily navigate.
