Having students scribe lectures: can the instructor choose any license? For each lecture of a course, a couple of students are assigned to scribe the lecture, as part of the course requirements. Can the instructor choose any license he wants for the scribe notes? E.g. CC BY-SA 4.0 or CC BY-NC-SA 4.0 in case the instructor is considering compiling and releasing the scribe notes publicly and is fine with people re-sharing them? Or are students entitled to decide under what license the scribe notes should be? I am mostly interested in the United States but curious about other countries as well.
I'd ask the students to transfer any copyright to me, formally if need be. In any case, the scribe is writing down what you are writing on the board, so the contents is morally yours in any case.

Presumably the result will undergo wide edition by you, so this is mostly moot.

[A student did transcribe my scribblings a while back; some things  got misunderstood or I plainly messed up, a lot of cleanup was needed, and for the next version I added several examples and clarifications.]
