Only 4% of the students said they'd ever had an online conversation that made them uncomfortable, and only 2% said an online stranger tried to meet them in person. In fact, after surveying 1,277 students, the researchers found exactly one who reported they'd actually met a person from the internet without their parents' permission — and described this as "0.08 percent of all students."

In fact, 76% of parents expect social networking will improve their children's reading and writing skills, or help them express themselves more clearly, according to the study, and parents and communities "expect schools to take advantage of potentially powerful educational tools, including new technology."

Well-integrated technology opens social networks for students and allows children to develop key social skills, according to two recent studies conducted by researchers at the University at Buffalo, State University of New York, and the University of Illinois at Urbana-Champaign.

When asked what they learn by using social networking sites, the students listed 'technology skills', followed by 'creativity', being 'open to new or diverse views' and 'communication skills'.

This issue is all about trust. Schools don’t trust students or teachers to do the right thing. Companies don’t trust employees. but the problem lies not with the technology, but with with setting expectations and ensuring those expectations are met. When a company blocks access to social media, it is blocking access to its own future growth and when a school blocks access to social media it is blocking access to a student’s future growth.

Youth engage with others to work out boundaries, to understand norms. This is how they learn power and authority, how they learn the networked architecture of everyday life. It's easy to eschew this, to argue that this is irrelevant, but most people spend a decent amount of their time working through social issues as a part of being an adult in this society. We talk about it as "politics" usually but it's about people. And teen years are where this is worked out.

Since we're using social network sites as a case study, let me point out one of the places where they FAIL miserably. On social network sites, you have to publicly list your Friends and you have to have the functioning network to leverage it. What happens if you're an outcast at school? Does bringing it into the classroom make it worse? What happens if you're forced to Friend someone who torments you because you share a class? And then you have to face that person in your "private" space online as well? Bringing social network sites into the classroom can be very very tricky because you have to contend with social factors that you, as a teacher, may not be aware of.

It's critical to realize that just because young folks pick up a technology before you do doesn't inherently mean that they understand it better than you do. Or that they have a way of putting it into context. What they're doing is not inherently more sophisticated – it's simply different. They're coming of age in a culture where these structures are just a given. They take them for granted. And they repurpose them to meet their needs. But they don't necessarily think about them.

Educators have a critical role when it comes to helping youth navigate social media. You can help them understand how to make sense of what they're seeing. We can call this "media literacy" or "digital literacy" or simply learning to live in a modern society. Youth need to know more than just how to use the tools - they need to understand the structures around them.
