As a teacher I loved that article. Good old long form journalism too. I find that the longer I teach (29 years at last count), the less conventionally "strict" I am. Kids, even the seemingly incorrigible ones, respond to compassion, efforts to understand, and, yes, discipline. But they don't seem to respond to assertions of absolute authority. Whether they "should" or not is immaterial in the moment, when you are losing control of a classroom.
As much as possible I practice preventive discipline. For example, I hung a shoe holder with clear pockets on the inside of the door. The students drop their cell phone into their designated pocket when they enter the classroom. I put things in the pockets that they take out when they deposit their cellphone. Sometimes just a Hershey Kiss or such, but sometimes a note of encouragement, a congratulations for a big effort, or an expression of concern. Also reinforcement of any trait that I know will be valuable to happiness and success as an adult but might not seem desirable in high school.
This has served me well and I have had so many students come back and thank me later. My stress levels have gone way down too. Win win! I will be saving this article and looking into these methods further.
