I'm optimistic, so I really do not anticipate any discipline issues with my students this school year. As a high school student you have spent many years already being groomed for how to control your own attitudes and manage your own behavior...or at least I hope so.
Yes, I'm optimistic...but not unaware. I do realize that sooner or later, we all face issues that challenge us to the very core of our being. And when we are challenged emotionally, spiritually, or physically, some of us unfortunately act out in unacceptable ways. What can we do to both prepare ourselves for these triggers AND quickly overcome them? I'm glad you asked.
I came across the most wonderful piece of advice from Thich Nhat Hanh. (If you haven't heard of him, please do use Google or Wikipedia to found out more. I encourage you to read this and adopt it for your personal use, not just on difficult days, but EVERY DAY. Let's see what a difference it will make in our classroom environment!
Breathing in, I relax
Breathing out, I smile
Breathing in I feel calm
Breathing out, I feel good
Breathing in, no more anger
Breathing out, peace and quiet.
Can you imagine what our class would be like if we all do this before, during, and at the end of the day?
