A bit of background: My girlfriend is Taiwanese and will attend TesDaF (German test) in a week. She has been previously learning for about 8 months now while being in Germany. So far, all points (writing, reading, explaining) except the listening, are great.
Her biggest problem right now is the listening.
- I've been reading news articles to her, letting her take notes and asking her questions
- We've been hearing radio / watching TV and then talked about the content of what we heard/saw in German
- I let her ask additional questions to the salesman about products we are about to buy when we are in a shop (= improve her "street German" understanding)
Sadly, I think we arrived at a dead point. Her understanding doesn't seem to match the TestDaF C1 level right now. I also can't see any improvement with this "practice" methods.
The next point is, that if we're not actually tracking her understanding, everything works way better. For example, if I just normally talk in German to her, she understands pretty much everything. Her understanding diminishes the moment she starts actually concentrating about what I say in order to attempt to understand as much as possible.
What would other ways be, to improve the listening comprehension?
