The truth of course, is that life is not like that. Learning English is easy. But it is going to take a long time and you are going to have to work hard. These schools seem to emphasize the fun part of learning but ignore the effort part. Perhaps students will learn something from just being there but these schools foster a sense of it all happening in the classroom.
Homework is virtually unheard of and preparation for class is labeled cheating.
Internationalization is a buzz word that no one seems to fully understand. It has more to do with holidays abroad and Channel clothes than real intercultural communication. It is a consumerist idea neatly packaged to appeal on highly superficial level to the emotions rather than the intellect. Learners in this environment are nothing more than pawns of a multi-million yen industry that is exploiting them by raising their expectations of what can be achieved in a given period of time with limited resources. After all, few of the students actually make any progress and most give up after a few years and so regress in terms of ability.
