Hi Joel,
Sorry to hear you are having some problems with behavior in your classroom. I hope you can get some good pointers from your mentor teacher and perhaps others at your school. It's hard for me to respond when I don't know more specifics. Does the school's behavior system work in most cases? Can you pull those disruptive students out sometime and ask for their support?
By the way, are you available for the intern seminar with me on Tues., Oct. 13 from 4:00-5:00 in 606 Allen Hall.
Email me if you have questions,
Kaye :-)
