20 seconds into a lecture that is part of a course that belongs to an international (read: English-language) master's program, and the lecturer actually asks, "Does anyone want me to hold this in English, or is German okay?"
While German would be no issue for me at all, I know there are several students present (because, y'know, mandatory presence in this #distanceLearning lecture) who prefer English. And I know some of them might prefer not to go out there and say "please speak english".
We're listening to two people talking about two different kinds of ... airplanes. A-320, and F-16. Just to remind you We are Computer Science majors. In masters programm called "Media and Human Centered Computing".
The announced title for the lecture was ... "Crowd Science". I pointed out that gap, and that I don't get where this is going. "Yeah, that was my mistake, I'm sorry. If you're not interested, you're of course free to leave at any time." We're not. Mandatory presence, remember?
