Useless waste of time. Kids/teens WILL learn how to sms, phone, play games and hack without having a computer shoved in front of them.
Many years ago my better half was a teachers aid, and I would visit from time to time for an hour or so (I knew the principal of the school too ) . It seemed to me that MANY of the teachers were in the teachers lounge drinking coffee and smoking.
I also had 2 step-kids, and the easiest way to keep them out of my hair was to install the latest hello kitty game on the computer and sit them down in front of it.
So, knowing these 2 facts, what are the teachers going to be doing?
