"Unmonitored and unrestricted access to the Internet by children is a growing and alarming problem,"the Police Chief said. Reports suggest the kids were exposed to unrestricted content on school-issued iPads outside of school. This has sparked a raging debate, as you can see here, here, and here, on who is really to blame, and whether there are deeper issues at play.
For parents, and schools, this is not an academic debate any more. James Steyer, CEO of Common Sense Media, and one of the saner voices in this debate, suggests that you take the time to learn what they are interested in and "share your opinions so as to help your kids develop the ability to view media critically." Essentially, engage, be connected, and stay involved in their online lives.
