Explaining QR Codes

I'm sure you've noticed these boxes and wondered what they were. I'm quite confident that most of the teachers in my school do not know about them. QR stands for Quick Response, and is made up of black modules in a square shape on a white background.Actually, you could call it a 3D bar code.  The encoded text in the square can represent a web address or text. Camera phones (with a QR app) or QR readers can read the encoded message. If you can scan the QR code I have on this page, it will lead you to my website, A Media Specialist's Guide to the Internet, where you will find teacher resources by grade level. QR codes are used for many applications, whether it's in an advertisement in the newspaper or on someone's business card. Believe it or not, there are many ways to use QR codes in education. Here's a great presentation put together by Steven Anderson which offers many suggestions by other teachers how they use QR codes in the classroom. I'm sure your students will love the idea of using their smartphone in the classroom; that is, of course, if cell phones are allowed in the classroom.
