Ferlazzo's classroom management

I am using the ten actions Larry mentioned in his blog entitled “When a good class goes bad”. The most effective to my classes is when I call parents if my students have done well. The parents are very happy about the news and my students are striving to do good for me to call their own parents. The next best is starting an “A” grade and letting the students know that it is hard to keep an “A” grade.
I have attended trainings for classroom management. But when I read Ferlazzo’s classroom management “why do you let others control you”, his strategies are new to me. All the misbehavior or problems he encountered from his students are similar to what I am experiencing from my students. I will try these to my classes.
