147 – you have obviously never worked with children with autism.
I have never heard of a PDD classroom since most PDD kids are mainstreamed where I come from. There are many autism classrooms though and although I cannot speak for this scenario, and I don’t even know if there was such a scenario, I have been in many situations that sound exactly as described and the reason the chair is pulled away and the shoes are taken off is because they are being hurled into peoples abdomens. They get them back when they are back in control.
Don’t be so quick to assume you have a clue. Most one sided stories are one sided.
