Q: Is there an app available that will allow me to put a presentation on a class set of ipads that forces the ipads to follow along to the master presenter? So that students cannot change the screen as the presentation is going on?

You might not be able to do this anyway. I'd imagine that the iPads are locked down to prevent users from installing and configuring apps like this. Contact your school IT support.

You might also ask this question in the iPad in the Enterprise forum. I do not know how to do this but it seems like a great idea.

Here's one possibility:

The only way to keep students in the presentation, though, would be to lock the iPads to that app via the Guided Access mode:

Whether you can do this remotely through one of the various mobile device management (MDM) soutions I don't know.

You can use one of the accessibility features called guided access, so they can't fool around with the iPad, but they can still look at your powerpoint.
