How to quiet the notification to students during the revisions of teaching materials?
if you're just changing a page, or typos in instructions or quizzes or something like that, there's a checkbox at the bottom of the page next to the save button. if it's checked, users are notified, if it's unchecked they shouldn't.
However, if you're changing grades or feedback, they'll get notifications no matter how you do it (unless that user has muted that type of notification).
By default, I always leave that unchecked. If the change is significant enough that I really want students to know about it, then I'll create an announcement or send a message.
