We have all seen them. They seem to be everywhere these days. Those little black and white boxes made up of seemingly random squares.
But what exactly are QR codes and how can they be used in education?
QR or Quick Response Codes are a type of two-dimensional barcode that can be read using smartphones and dedicated QR reading devices. They can link directly to text, emails, websites, phone numbers and more! QR codes can be found on product packaging, shop displays, printed and billboard advertisements as well as in emails and on websites.
If you have a smartphone like an iPhone, Android or Blackberry then there a number of different barcode scanner applications that can read and decode data from a QR code. The majority of these are free, and all you have to do once you install one is to use your phone’s camera to scan the barcode, which will then automatically load the encoded data for you. Examples of barcode scanner applications include Red Laser and QR Scanner
At this stage you might be asking yourself “So what? How does this affect my classroom or library?” Well a recent survey has found nearly half of all Australian adults now own a smartphone and that number growing on a daily basis. The Australian Communications and Media Authority (ACMA) study found a 104 per cent increase in smartphone use in the 12 months to May last year, bringing the number of adult smartphone users to more than 8.5 million (ABC, 2013). QR Codes have the potential to have a major impact upon society and particularly in advertising, marketing and customer service with a wealth of product information just one scan away. Why can’t school libraries ‘get a piece of the action’ by using devices that students and their parents are comfortable with to increase advertising, marketing and customer service?
You can make your own QR codes using designated 2D barcode generators, some of which are listed below. QR Code generators that are currently available include:
So once I can generate QR codes, what do I do with them? Some ideas for use in the classroom or library include:
- For students to view YouTube clips for information
- Put QR codes inside books to send student to reviews of the book.
- Add QR Codes to student homework which link to video tutorials to help students if they are stuck on the problems.
- Place QR codes in the school year book that link to videos on the school’s YouTube channel and various internet sites.
- Get kids to the correct website or web resource for the lesson (place QR code on top of work page). No more students saying that they can’t find the site or the URL doesn’t work!
- A QR Code Quest: a Library Media Scavenger Hunt

I know what you are saying: “My school has banned mobile phone use in school time”. If your school will not allow students to use their phones in class time for educational reasons try using iPods or a class set of iPads or tablets. I have also used the webcam on laptops to scan QR codes as the school would not allow students to use their phones. It is a little more cumbersome but it is achievable.
