QR (Quick Response) codes are symbols that can be scanned with app-enabled smart phone cameras that can link to almost any form of digital content. I have had QR codes that point to my class website, as well as to my email, posted in my classroom for some time.
In order to create these I used QR code generator on qrstuff.com. At this point I haven’t used them for much else, but can definitely see how they would become increasingly useful as more and more students begin bringing devices to school that have adopted BYOD policies. Scavenger hunts, content and video links on handouts and projects, various types of enrichment…the limit is pretty much the imagination of the teacher. QR codes give schools the opportunity to use the technology that students are interested in (namely their phones and tablets) to create a more immersive and engaging learning environment.
