Hand a teacher an iPad and they need app specific training and worry they won't know how to help kids be successful with them. Hand a 7 year old an iPad and you get "The Molly-Nator".
This kid knows what it means to air drop something. He took pictures and edited them in iPhoto and Photobooth. He also asked me to upload it to YouTube so everyone else could watch it. He asked if I could tweet it to his awesome kindergarten and 1st grade teachers so they could see his new puppy.
So instead of blocking YouTube from schools or fighting to keep iPads out of kids hands in schools because of the fear of what they may do with them, think about the world we are living in. Our kids have technology at their fingertips. Their world is different than the one we grew up in. So instead of fighting it, help them learn how to use it responsibly before they leave your somewhat safe environment.
