In my previous life as a visiting teacher (not much changes, does it?) I had seen classrooms use Make Your Day discipline system. I didn't like it.
Basically, the program says you chose how your day goes and that no one has the right to interrupt another's learning or safety. There are various steps that the students move through. At Step 1, the teacher walks up to the disruptive student, tells them they have chosen step 1 for X behavior. The student goes and sits in a chair and FACES THE WALL! After less than 5 minutes, the teacher walks up to the student, without touching or looking at them, asks the student if they know how they chose step 1. Then the student is asked if they are ready to return to their desk.
If the student is unable to sit and face the wall for five minutes, they move to step 2 where they STAND FACING THE WALL! I don't know what the next step or two is but the final one is a call home and parent pick up.
At the end of class, the teacher has to take five minutes out of instruction time to go through the class list and have all the students state how many points they earned out of 45. If they say less than 45, they must state why. For example, "43 for being off task." Students are pretty honest here. They have to have some average for the week. I don't know what the consequence is if they don't.
Today was my first day implementing the program. I was in middle school language arts and social studies classes. Most of my students were great, but those that weren't really weren't. And let me tell you, the Make Your Day program did not work. I had two students 7th period who really needed to get the Hell out of my classroom. How many times do you send a kid to sit facing a wall? I spent so much time sending those kids to step 1 and telling them to ignore each other that I neglected other students who needed my help and were asking for attention appropriately.
Currently, not a fan of this system.
