Well, this one was a bit of a mystery to me. Not having a smartphone put me at a bit of disadvantage for this one as well. To figure this out, the first thing I did was download the image. It was during this time that I saw its file name- qr_figureitout. I typed in "qr" into google and was able to read about it on wikipedia. After reading about it I knew what needed to be done.
At the conference, I made an observation. I was one of two individuals walking around with a regular cell phone. It was like I was back in junior high and missed out on a fabulous trend- Giga pets, pokemon, or more recently silly bandz. (I'm not sure if it is spelled with a "z" at the end, but all the kids and rappers seem to be showing plurality with a "z")
So, I got a smartphone! Got the QR decoding app, and figured it out. The link it sent me to was a very interesting blog. But, good luck convincing teachers and administrators that cell phones should not only be allowed- but used in class. I mean it- wish me luck!
