What's the deal...

...with the trend for students to "raise" their hands by leaning their elbow on their desk and putting their hand in the air? Sometimes, they barely raise their hands off the desk. I can't tell you how many times I ask students if they're raising their hands when they're not because I can't tell the difference anymore between a student who's raising his/her hand and a student who is playing with his/her hair or pencil or the air.

I blame me, though. If I stop responding to students who raise their hands this way, they'll learn that they need to stick that puppy straight up to be recognized.
