Are there any special skills we'd need to teach the students?

A cold saw does spin very slow, which makes it slightly less intimidating (maybe a plus for a hesitant student).

-Assuming you are cutting properly, the speed is on par with horizontal band saws.
-I can't speak for the cheaper ones, maybe someone else here has some experience with those.
-Yes you still pull down on the blade.
-As far as skill required, a cold saw is a very simple tool to use. Very similar in setup and procedure as a miter saw without the the loud noise and fast blade rotation.
