A 2D or QR (Quick Response) code is a two-dimensional bar code. Although they were initially developed and used for tracking parts, they are becoming used more broadly. QR Codes may store information such as address and URLs and can be found on magazine pages, on signs, or on any object that users might want additional information about. People with mobile devices equipped with a QR reader can scan the QR code to obtain additional information. Linking from physical objects to virtual information is called hard linking. You can generate your own QR codes by using free QR Code generating sites.
How can this be used for learning? Here’s an example with tons of implications. Ubmark has added QR codes to Jules Verne’s book Around The World In 80 Days. With a mobile phone equipped with a QR reader, the user is taken online to participate in discussions about the book, follow along on interactive maps, and listen to audio or view video. And a teacher describes using QR codes to help students learn to identify the major bones here.
