RE: I’m not sure. Usually the projectors work fine, and they function well as a screen, but I’ve never seen the pens/eraser/interactive pieces work.
SO, it’s simply a matter of technological limitations, not the concept itself that’s the problem. If the technical issues can be solved, will the Smartboard idea be useful?
I think it could be. I'm not against Smartboards, unlike the usual Luddites you see around here, just that in my experience they're not supported well. And that support costs money.
