An old video I made about using QR codes.Before I left my last school I covered all the toilet doors with laminated signs. These signs would have a quote from a book, with no details telling the author or title, but just a QR code linking to the Good Reads site, or a YouTube book trailer!
Now that I work in a 1:1 iPad I am able to use them in a range of creative ways. Mostly I have been putting them in books to enhance them - so either linking to videos and other resources to support the books, or linking to our book club or to an authors website. I am also going to start using them for new students, so that they have QR codes for all of their iTunesU courses!
On Pinterest I have pinned lots of ideas for using QR codes in school too.
