When my oldest was going into middle school the district started providing devices for the kids to use in class. There was breathless hype about how this would usher in a new age of technological competence and improved pedagogy. I asked the district IT folks in attendance what types of controls they had in place to prevent misuse -- watching YouTube, open browsing of the web, etc. They had literally nothing in place.

You can guess how that went.

I love Vernor Vinge's works, but the worst prediction of his ever, just 180 degrees totally in the wrong direction, was _Rainbow's End_'s treatment of technology in education. His take (and this was as late as 2006!) was that unfettered access to technology would turn elementary students into a cohort of genius autodidacts. Fast forward to 2025 (coincidently the date the book is set in) and unfettered access to technology has turned children into feed-consuming zombies.
