#copyright question for all you nice people!

My university (in Italy) has moved to online classes, using microsoft TEAMS, for the coronavirus outbreak.

They published a regulation saying that all content from a class, which is a conference so everyone can chime in talk and show, is copyright of the university.

Now that sounds weird, I would have expected each person to own the copyright to its own contribution, since we didn't sign nothing for it, and the university to own dick bupkis.

Could someone help me here? Is the university trying to bullshit us?
