I remind myself they are people
It sounds so simple but it is hard to do when patience is tested. I put myself in their shoes and think about how I want to be treated. When I catch myself getting frustrated I check myself quickly. This keeps me treating students with respect every day.
Don't talk bad about students to teachers
No one wants anyone talking behind their backs and that's what happens when teachers complain about students. What's worse is that it happens in front of students when teachers have conversations in the hallway or in classrooms during class time. Whatever my opinion about a student stays with me.
Stop being cynical, snarky, and sarcastic
It's really easy to use sarcasm and cynicism in conjunction with snarky comments with students. While teachers may think it is funny, the student will likely feel demoralized, embarrassed, and stupid in front of peers. The easiest time to snark out is when students are misbehaving or when they don't follow directions. It took me some time to get past this, and I still catch myself doing this sometimes, but keeping the snark, cynic, and sarcasm to nothing tells students you care about them.
The best part about my day is when I get to have fun with students and that is every class period. When I have fun and they have fun learning gets a whole lot easier. What's awesome about this is that I get to be a real person with real people and students love that.
