I think these pens may prove usefull in some cases - not sure they are on the school's radar yet...
My easy child was actually looking into it for college so that she could put her notes on the computer, but found that just typing them on her laptop in lectures was cheaper!! She was actually drawn to them originally because they also record audio (i.e., if you can't read your notes or the technology can't figure it out, you can hit a button and it will playback in audio from that point on).
I had looked into it a little for my difficult child but his issues involve more non verbal lds and dysgraphia - have to be able to write notes for the pen to work! Also, I wondered if the whole pen thing might be more distracting to him. Part of his "deal" is that he prefers writing in pencil because the friction of the lead on the paper. Plus, I wouldn't trust my 15 year old difficult child with an expensive piece of technology like that at school!
But I think it definately has possibilities...
