Me: “Are you wasting time on YouTube?” My teenage son: “No.” I go look at the computer screen. Sure enough. He’s watching YouTube, not writing the paper that's due in 18 hours. I give him a disapproving look. “It’s not a waste of time,” he informs me. “I learn a lot on YouTube.” This is actually a conversation we had quite a while ago. I long ago admitted that I was wrong. Not entirely. He should have been writing his paper, of course. But I was wrong to assume that he was wasting time because he was on YouTube. He does waste a lot of time, by my working adult standards anyway, watching silly jokes and anything that will make him laugh there. But he also learns a lot. After engaging in more than one discussion with him where he clearly knew a lot more than I did – and I read the news every day -- about current events, I asked him to show me his sources. Some of it was a bit raw – cussing and whatnot – to share here. But some of it was outstanding, youthful, edgy, current, and highly informative. YouTube partners with some outstanding educational sources for educational content, including Stanford, Harvard, PBS, TED, and the Khan Academy. So these days I’m more likely to suggest a YouTube video to my kids than to ban the site. I figure if I send them to content that’s funny, entertaining, and educational at least that’s time they are not spending giggling as they watch a cat fly out the window. (Though there is nothing wrong with feline-antic induced hilarity in reasonable quantities.) Check out the video I included here. Or for an ever-changing daily menu of funny, fascinating, often beautiful and always educational videos just check in at YouTube EDU.
