A few weeks ago, I was browsing TheCornerstoneForTeacher's website and found this classroom management video. The video notes some techniques about acquiring and maintaining the class' attention, mostly through the use of nonverbal cues.
The techniques are from a book called Teach Like a Champion. I haven't read it yet, but I'm looking at reviews now and I'm curious about it. There are a few things in the video that I want to borrow. Most of them are things we're told repeatedly to do with students (such as correcting behavior and immediately shifting the focus elsewhere), but I like how they are achieved in this video.
"I don't have Marissa, but I do have Jasmine." It corrects the behavior, and also brings to attention someone doing something positive.
What's really cool are the nonverbal cues. Without saying a word, the first teacher in the video is able to tell students to put their hands down, keep their eyes on her, listen carefully, pay attention to what's on the board, sit up properly, and probably several other things! I like that, because it means she's trained them to recognize and respond to her cues, and it maintains a lot of order and prevents interruptions.
With subbing, of course it's a little harder to teach students some cues when you're only with them one day, but I still think there are some things in the video I'd like to try myself and keep in store for when I am a regular teacher.
