Procedures reduce the need for rules and discipline. I'm asked this question all the time. Then I tell them to work out the steps for that procedure. The next day, they introduce that one procedure to the students. They explain it, model it, and rehearse it and rehearse it and rehearse it.
All teachers know that students learn best by doing.
The only way a teacher can have a classroom in which kids can learn by doing, by discovery, by activity, is to establish routines and procedures. Students cannot be free to create without procedures and routines. A teacher cannot be funny or loving or creative in chaos. We felt that most education books were drab. We wanted to lay this book out in a more graphically pleasing way.
