[nullandvoid]

I think as a child your mind is pretty easily distracted ( looking at you IT classes of my time where 90% + of the class would be sneaking on miniclip every time a teachers back was turned )

It's pretty essential if we're going to have those connected devices in the classroom there is a way to control it.

I would prefer rigorous blocking over teacher control - but reasonably I think it's kind of necessity in a classroom setting.
