Hmm, I'd be a bit dubious about a correction for making a scene because then she would be succeeding in getting your attention and, like children, dogs don't care whether the attention is good or bad. If she gets your attention once, she'll create a scene again to get your attention...again.

Demanding attention is a way for dogs to climb the pecking order and become higher ranking and, as most people fall for it every time, the dogs usually succeed in this when they do it with people. They do it in a variety of ways as well.

I agree with the exercise to tire her out and having her spend some time in the crate whilst you are around and providing her with a toy she can chew on or whatever.
