To insure that I am calling on all of my students equally, I put everyone's name on an index card. I keep the deck of cards with me and instead of calling on raised hands, I call on the next card in the deck. This prevents all those Oooo! Ooo!-ers, helps me make sure I'm not just calling on those who raise their hands, and keeps all the students on their toes since they don't know when their card will be next.
