I have an advanced adult student that I don't know what to do with (I am a new teacher).
She's intelligent, generally doesn't have any problems with understanding me, and expresses herself pretty well, but still makes a lot of errors with verb tenses and seems to lack vocabulary. She really has no use for English in her work or daily life, so our class is the only time she practices. (I'm not allowed to give homework in my job.) She mostly wants conversation, but doesn't seem to object to me instructing her in grammar and things like that.
When I quiz her she knows most of her grammar rules, but fails to apply it to her speech naturally.
What activities can I do to force her to use the correct verb tenses in conversation and increase her vocabulary? And also not bore her. I'm not a fan of most of the activities I find on the internet, which seem very childish and silly to me.
