In this post he talks about the student behaviors to which teachers attend. He concludes by recommending teachers "create a group of three to five teachers (or more) who will rotate in and out of each other's classrooms about once a month, perhaps during their prep periods. For 15-20 minutes, the teachers should count how many appropriate and inappropriate behaviors the classroom teacher attends to.
Then, each teacher who has been observed tries to raise the number of appropriate behaviors they attend to and lower the number of inappropriate behaviors they attend to. With time, the results should be self-evident. Good luck!"
