A master teacher I meet 24 years ago had every bit of his room covered with posters, bumper stickers, signs, specimens, and gadgets. He said, "If they are not going to listen to me, then I hope they learn something from the walls".
I like that.
It's fun to hear students comment about them. Some are goofy but most are serious.
One of the things I put up on my wall are a series of science statements that start off with DID YOU KNOW...
