Oh how I remember these days of a A.D.H.D child in school... our oldest was a nightmare until we saw one doctor..oh the help he gave us was excellent. He said the one most important part of a child with A.D.H.D.. is clear cut guidelines. Teachers have a rough job as it is, and then to deal with a A.D.H.D child can be rough on some teachers. But they are adults and should know no child (nor adult) is going to respond to being the center of attention in a negative way. The teacher has to stop and think..how would I (or my child) want to be treated in this situation. I am glad your family has brought this issue to light..as this teacher did wrong.
