Doubts about CLIL: food for thought?

In the most recent IATEFL magazine, "Voices", Chaz Pugliese (a trainer and author working out of Paris) voices his doubts about CLIL in his regular column. Here are some of his concerns. What do YOU think?

• English will in the long run threaten some weaker European languages.
• In several European countries the language level requirement for a content teacher is B1, so teachers' English is not good enough.
• The lack of adequate teacher training for CLIL: a two-week summer school is not enough to teach a CLIL class (just as a two-week biology summer school would not be enough for an English teacher to re-train to teach biology!).
• CLIL seems to rely on the fact that languages are acquired, not learned. Second language acquisition research, on the other hand, indicates that focus on noticing and practising language is needed for internalisation and automaticity. Learning by just using the langugage "just doesn't do it".
• Some research in Hong Kong indicates that CLIL learners' motivation suffered in CLIL classes.
