The teaching of English as a foreign language is a global industry. It has many millions of customers and employs thousands of teachers and other workers. It has been a global industry, in fact, for several decades. Yet the basic way it operates and its basic teaching methods are never debated. Nor is there discussion of whether people are really learning English or any other foreign language better than they did forty or fifty years ago. Instead, the industry just gets bigger and bigger.
