"Can you elaborate?" to a teacher?

Can a student say "Can you elaborate?" to a teacher when the student did not understand what the teacher has just explained with a good length?

I think "Can you elaborate?" is something that is said during a presentation at work, such as when you are interested in the idea and want to know more about it before they gave you much detail. Saying that to a teacher especially after the teacher has given enough detail does not sound right to me, but I wonder if any native speaker shares that feeling with me.

Thank you.

    You are correct, you only say that when you want more detail than has been provided already, not because you didn't understand.

    Some teachers might consider this insufficiently deferential, framed, as it is, almost as an instruction.

    Could you elaborate, please? would be entirely acceptable, I think.

    Teachers' stock in trade is to say the same thing in different ways, so I'd be happy with the request.

    It sounds wrong for two reasons.

    1. It doesn't sound polite.

    2. It doesn't make sense. If someone speaks very briefly about a subject then you can ask them to elaborate - that is you ask for a lengthier more detailed description. However in your scenario the teacher has already explained at length and so they have already elaborated.

    What precisely do you want the teacher to do?
