One thing is clear, it will give me a lot of work, because these students get a lot of effort to get excited about something. Unfortunately, most of them take German as a not very nice language. It would probably not be in vain to try to talk to them about it for part of the lesson and play them some interesting examples or songs. Or show them some photos of themselves or tell them a few experiences from Erasmus.
