I used Internet searching to find videos and resources that would show easy, step-by-step instructions. My first "ah-ha!" moment came when I realized I didn't know 1) how to remove a bike wheel and 2) the actual parts of the tire. There's a tube inside!!! Whaaat? I also had to buy tools! The videos were great, and the step-by-step websites were fantastic, too. I also made sure I asked any questions I had when I bought the materials at the bike shop, just for clarification.
I would definitely use this approach to learning again. I might feel self-conscious asking the same question of a live human being 25 times, but I would be just fine rewinding and replaying the same video segment 25 times. I would certainly advocate this approach to students - they might be ahead of me here, as I believe all of the Rainbow Loom bracelets they created last year were self-taught designs using YouTube! The real world is full of reasons why Networked Learning is a wonderful integration and application of technology. It is meaningful, applicable, and can be, as we've seen with bracelets, duct tape art, etc, a real motivator.
Anyway...I successfully changed a road bike tire tube! Woohoo! My video has an entire outtakes reel since I made so many mistakes. My daughter and I had a lot of fun filming and shared a lot of laughs. Enjoy!
