What is a QR code?
QR code is short form for “Quick Response Code”. It is essentially a unique, pictorial link to a website, which is accessed by scanning it with a QR code reader on a smartphone or tablet device. What does it look like? Generally, they look a little like barcodes. They are a randomly generated collection of black marks on a white background that are completely unique. How do they differ from barcodes in supermarkets? On barcodes on the back of packaging, the barcodes are made with vertical lines, alternating in black and white and of various thicknesses. The code is capable of holding 30 numbers, and the combination of these numbers dictates what the machines think the code is for. On a QR code, the image holds up to 7,000 numbers, which allows for a greater range of unique outputs. In essence, they can do more. How are they of use to students? In the classroom, pupils may use QR codes to direct family members to online work displayed on class blogs, videos, pictures, or websites. Teachers may use them to link pupils to homework or useful information. Pupils may also write their own online work and link their teacher to them by creating their own unique QR codes. How are they of use in the real world? QR codes can be put on anything. Bus stops, newspapers and magazines, t-shirts, books. Anything printable. How do I generate my own QR code? By visiting one of the following websites (others also exist). http://www.qrstuff.com/ http://qrcode.kaywa.com/ http://quikqr.com/ Have a go at following the following QR codes! One is for the computing primary national curriculum (captured from the University of Manchester Computing handbook) and the other is for the Primary Newbie twitter account.
