We all have our share of attention seekers in our classes that's a fact. The one you mention is a bit of an extreme case, I mean with the violence, chair throwing and all... I personally work with students with age groups ranging from 12-16 and I guess that if it was to happen to me [thank god it's not the case...yet

] I would try by all means, get in touch with the kid's parents and would involve the rector together with the rest of my staff for sure. Anyway, as you proceeded, you found out that your student's problem was most probably connected with his dad's carceral encounter... It's so often the case isn't it. A pupil behaves real bad and 9 out of 10 it's a family issue. I wonder sometimes, if I'm myself, more of a teacher or a councellor

. Strange times. So how to deal with attention seekers then? From what I learned from training, it doesn't matter too much which kind attention they get, be it positive or negative. Actually they don't care: it's the attention they're after. So the idea is to give them positive attention but... at random. That is, not at the time when they are misbehaving. It can vary between eye contacts, smiles, words of encouragement, regular checks on their progress or the casual pat on the shoulder. If the student is good at writing he could be encouraged at reading his stuff in front of the class. If he enjoys visual arts, his drawing could be pin on the class-board etc. All colleagues working with that child should also feel concerned, so that there is a uniformity of approach towards the method.
