The QR Code - Tiny Box. . . BIG Information

We've all seen QR codes. Those little squares of black and white pixels might look meaningless to the naked eye, but with a quick scan with a QR code reader, you'll quickly find there's more than meets the eye! They are used to quickly launch the viewer to websites, videos, images, and even file downloads. What appears to be a random collection of black and white pixels is actually a complex code with an interesting development story.

These little boxes present some intriguing possibilities for education. I've used them at conferences to easily provide my website address to attendees. This article from Free Technology for Teachers describes how teachers might create treasure hunts for their students using QR codes. Finally, what an interesting way to display student work! As discussed below, Cindy Smith's 7th grade Computer Information Technologies students will have their work displayed through QR codes for the Middle School Open House on Wednesday, April 29, from 3:30 - 7!

Interested in checking out some QR code generators? Kaywa QR Code is a great place to start! This source allows for the unlimited creation of static QR codes and a limited number of dynamic QR codes. The difference between the two? Dynamic codes can be changed when needed. How about QR readers? A quick search in your mobile device's app store will return numerous results. I run QR Code Reader on my Android telephone and it works just fine!
