We never let the students bring the blade up while spinning regardless of material; we find it better to keep the procedure the same.

I'm sure you haven't, but that's not really what I was getting at.
One thing our shop mentorship identified and focused on is consistency. Because we all, as experienced metalworkers (Some professionals, some amateurs) have different ways of doing things. And those methods are safe on their own. But, if you mix-and-match different parts of them, somebody could definitely get hurt.
So before doing any safety training this last year, we sat down and laid out exactly what method we were going to teach the students, and we tried to ensure it was the method that follows "best practices" or at least general widely-followed practices. That way, if our students go on into machining, like I did, they won't have to un-learn anything we taught. And we don't have to worry about them accidentally mixing-and-matching our methods, and those that are used out in industry/education.
I mean I don't want to tell you how to mentor or anything, just my $0.02.
