>I don't mind granting my professor a temporary license to evaluate my work
That's a weird thing to say, and I'm not sure you understand when a license is and is not needed.
If you write an essay and hand me a physical copy, I can then do whatever I want with that copy. I can read it, I can shred it, I can put it in a filing cabinet to gather dust for 20 years.[1] I can even give, sell, or lend it to a friend! I can do all this without needing any special license, because I own the copy you have given me.
What copyright prevents is me photocopying, scanning, or even laboriously hand copying it, and then passing those copies to other people. But while you own the IP, I own the physical copy.
With digital works, the rules are a little different -- if you e-mail me a PDF, sending it to someone else would count as creating a copy, and I'd need your license to do so. But the essential fact is I don't need a special license to hold on to a copy of it. And if you give me permission to send it to someone else, once they have it they can hang onto it as well.
[1] Universities will of course have policies on how faculty handle student work, but that's an orthogonal issue to that of copyright.
I'm sure you are familiar with non-disclosure agreements. Those, and many other, possibly implicit, agreements severely limit what you may do with your 'physical copy'. 'Owning' the copy in no way entitles you to do with it whatever you want. Even telling others you own the copy is something that is easy to forbid.
I was taking issue of the OPs use of the word "license." A license grants you additional rights you would not otherwise possess.
If I'm discussing what actions are, by default, allowed -- well, it isn't very useful to tag a clause onto every statement saying "Unless a legal contract/agreement prevents you from doing otherwise."
That's taken as understood, and only worth mentioning if it is a right or freedom you can't sign away.
