Most students just aren't aware of what good manners are versus being rude or disrespectful.
Therefore we need to teach them.
For instance, if we go out to our lockers, I model how to open up the locker quietly, hang things up properly, and then close the locker quietly. This might seem elementary to you, but if you actually show them what your expectations are, then in the long run, they will understand why they are doing it in the first place.
Another example is walking in the hallway. Most students say something like "He cut!" or "She pushed me"... even before we get out the door. So we have a saying that we say together that goes like this:
"My hands are hanging by my side, my eyes are looking straight ahead, I'm ready for the hall." (In addition, I shut the lights out exactly as they say the word "hall.")
If they can't do either of those things correctly (as a class), then we just simply practice during THEIR free time.
Oh, they don't like that!
But it works, and they know that I mean what I'm saying about being respectful.
Some kids have it, but most are still learning.
Jobs that fit this description are: "Lineup Organizer", and "Compliment Counter."
They love it, because they're in charge (even though I'm right there).... but that doesn't matter, because it's all about ownership of their learning, and this is yet another example of what we do.
Hope you have a great day!
