When I presented at MLA last year, my co-presenter and I called it "Beyond Duct Tape: Programming for Today's Teens". Really though, I have no beef with duct tape. It remains a staple in my programming wheelhouse--a sentence that I'm not sure makes sense and which also makes me want to slap myself in the face. ANYWAY!
I've found that teens need a lot more instruction than you would expect them to. I always hope that they will just play and create and end up with awesome stuff, but their imaginations just don't seem to go that way. I usually provide them with samples and instructions for roses and wallets, and this time around I had put in the newsletter that they could bring a t-shirt if they wanted to make a t-shirt bag.
While we did have a couple of reluctant ladies who I don't think ended up making anything other than a bit of a mess, most of the teens came well prepared this time around. I'd only allocated an hour--next time I'll make it two. They weren't ready to leave! I let them stay over for about half an hour, but I had tickets to that night's Tiger's game so I had to kick them out eventually.
Lots of the instructions that I have used before haven't been detailed enough for teens who haven't done these kinds of projects before, so I drew my own. Please admire my awesome skillz!
