Test Taking Environment

Just wanted to share something I've noticed in the classroom. When I turn off a set of lights during a test-taking situation, the room feels calmer. Students seem to prefer a set of lights off when they're taking a test or quiz, and I get the sense that it relaxes them. I originally only did it in one of my eighth grade classes when they asked, but then I started doing it in all of my classes. I ask them if it's okay to turn off a set of lights, and they all say Yes! Some want all the lights out, but I think that would put them to sleep. So I turn a set off, and it instantly feels calmer in there, which is great for taking a test. Of course I wonder if it enables easier cheating, but I don't think it does. I also give multiple versions which I hope prevents a lot of cheating.
