ClassDojo - manage student behavior

I have a particularly bad class this year.  It's just the one period that I have after lunch, but they drive me crazy.  I have starting using ClassDojo because it's an easy way for me to record the behavior in the classroom.  Students and parents have access to these records so they can see how they are behaving.

ClassDojo gives me the option of updating behavior instantaneously using a laptop, tablet, or smartphone and can be displayed via computer, projector, or interactive whiteboard. The availability of data engages students and helps actively shape behavior, thus creating a more positive learning environment in the classroom.

ClassDojo also automatically generates behavior reports that I can send home to parents or share with students. These reports have given parents and students insight into the classroom that hadn’t been previously available. I believe that providing students with feedback has allowed learning to flourish in my classroom, increasing students’ positive behavior and intrinsic motivation.

What do you do to track classroom behavior?
