Using QR codes for explorative learning

This is the 4th entry in a series of ‘putting the fun back into fundamental learning

QR codes are like a bar code, but rather than being made up of lines, are constructed of squares. An example QR code being below. A QR code is a graphical representation of a string of text, and they can be created by anyone, using something like


The above code is for the web address of this blog (

Most mobile phones that have the ability to take photos can read Qr codes – some will need to download some software (or an app) onto the device (usually free) – you then take a photo of the code, and it will convert it into the text that it represents. In the case above, because the text is a web address – if the phone is internet enabled, it will then go to that website.

There are many ways that QR codes could be used in education, some examples are:-

  • Land based colleges having QR codes next to plants in the grounds, so a learner can point their phone at the code to get more information about that plant.
  • Providing stretch information following an activity – lets say you have a printed worksheet that the students complete with pen and paper. If you want to give them additional reading materials, or additional optional questions – to put a long URL onto the page is of little use, as hard to type in a long URL accurately – but putting a small QR code in the bottom corner, allows them to just point their phone at it, and away they go.
  • Having a set of questions (which may be used on paper in the classroom) – but having some help information, or feedback information stored on a web address somewhere (this could be on the VLE, a Blog, a wiki etc.) create a QR code pointing to this, and then put this onto the document. This allows the students to attempt the questions first, then go to the additional information later on if they need to.
  • Creating information treasure trails. Setting up a trail, where the learners move around the site, locating a QR code – which contains information to do with the subject, possibly asking them a question that points them to the location of the next QR code. Yes this would take a bit of time to set up, but as allows, there is the option of setting the students the task of creating a QR code trail for their peers. The students would need to think about what questions to ask, where to place the codes, etc. Then create them (quite easy to do) and go and put them in the right places, then have fun following each others trails.

An example of something like this, has been created by an Australian PE teacher ‘Mr Robbo
