I know there have been a lot of blog posts (I'll link to them here.) over the past several years about using QR
Here is a Google presentation that I have used over the past several years to train teachers. There are lots of ideas for HOW to use them in the classroom pictured. Many teachers seemed to like the idea of using a QR code to "attach" a student's digital project (Ex: Prezi, Google Presentation, Stupeflix, or YouTube video) to their paper notebook such as a Intereactive Journal. That way, when students and teachers want to view all of the work around a particular topic, everything is right there. Very handy!
Recently, I came across this Prezi by Nicole Zumpano which is worth a view! She shares lots of different QR code generators and apps as well as some terrific ideas for classroom use.
Creating and Using
Since we are a Google Apps district, probably the easiest way to create them (in addition to Google Spreadsheets) is by using the goo.gl Chrome extension (which you should be using for a number of reasons anyway)! To read them, I have had great success with the QR Code Reader and Scanner app for the iOS devices although there are zillions out there and you should spend some time playing with several to suit your needs/personality!
If you need to create a number of QR codes, say you're making a self-checking workstation, then using this
formula is really handy (directions for setting this up is in my presentation above).
