According to Wikipedia, a QR code is " a specific matrix bar code ( or two-dimensional code ), readable by dedicated QR bar code readers and camera phones. The code consists of black modules arranged in a square pattern on a white background. The information encoded can be text, URL, or other data." Teachers can use this technology for a wide variety of educational purposes. In this excellent video tutorial, Red Squirrel demonstrates 11 ways you can use QR codes in your class (e.g: create handouts with links to online content; enrich your content by adding links to online videos, documents and PDFs where students can access more information about topics taught; create QR codes that can show answers to a specific exercise or instructions on how to carry out a certain activity …etc, make books interactive and many more).
