My school is high level and I'm told to teach the kids pretty solidly intermediate stuff. This means most of my classes are very dull affairs, there just seems to be no way to get any of the usual game activities to work for learning more than bare basic vocabulary. And the students are nowhere near native level so that sort of game is out too. They:re just stuck in the middling level of too good for simple stuff but not up to even simple native stuff.
Does anyone have any experience in high level high schools?
How do you make classes fun?
