Okay, let's assume the worst. You don't get help from the parents, other meds or the school district and you're on your own. What should you do?
1. Recognize that the student is a Long Term Project and changes in behavior will be very small ... and take a long time to achieve.
2. Recognize that the only thing you can truly control is your reaction to your student, so control your tone of voice. Some things you do, make his problem worse ... especially your emotional reaction ... so control your emotions by controling your voice.
3. Now, let's get down to concrete strategies. Make a list of all the things you want your students to do every day, line up, hand out papers, sit down, recite the class rules, open books, etc. Give your student (without his knowledge) a score 0-4 for each behavior (4 is best). Average these scores; this is your baseline. Your goal is to raise this baseline .1 a month which will mean that by the end of the year your student will have improved one entire level in his overall performance. If you don't start with a baseline score, you have no way of charting microscopic improvements. Recalculate this score weekly.
4. Of all the behaviors, pick out the one that is easiest for the student to improve. Then, look at the bullseye game which will give you a structure, no penalties involoved, in making microscopic improvements in this behavior.
5. Keep working as hard as possible on getting all the other kids to follow your routines ... the more structure your classroom has, the more your student's brain will "mirror" that structure ... no matter what his outward behavior ... and the more time you'll have to work with him ... because everyone else is on task and united behind you.
6. As you see progress, give your student small leadership tasks, "John ... when I point at you today, I'd like you to say, 'class!" ... and then give him some one on one practice at this.
7. Keep us posted on your progress.
8. After you've played the Bullseye game for weeks, you can still go on to the Agreement Bridge.
