We have similar rules for keeping your desk clear, electronics in your bag. I think the difference is having people walking the floor, which isn't effective if you only have 1 professor watching 50 people, in my opinion. It's also very difficult to know exactly how effective those preventative measures are, either in discouraging students from cheating or catching them when they do. It's apparently still easy enough to keep your phone in your pocket and pull it out onto your lap when you want to look something up. Honestly, I've always assumed it'd be impossible to cheat during those exams but have been proven wrong. In the most recent case, I and the person next to me were sitting in assigned seats in the front row, ~3 feet from the professor. He still wasn't caught, as far as I know. (I mentioned it to the professor near the end of the exam but she didn't catch him in the act). Even if she had, she'd have to be willing to go to the work of reporting him, attending the hearings, and doing the paperwork which historically doesn't result in getting the student expelled if it's the first time they've been caught. Lockers seems like a good way to prevent it, although phones are still easily hidden in a jacket pocket so you'd have to ban bulky clothing too.
