Marsha, my first step would be to implement a day 1 conversation about the consequences for violating classroom rules. I would include a discussion with students about their expectations of the consequences for violating the rules and would include the possibility to losing access to the classroom for a class period with no option to make-up any missing work. Next I would implement my plan and would request students leave the classroom if they are in violation of the rules. Over time students will follow the rules or fail out of your classroom. This of course would need the full support of your administration. James Jackson
