Thanks for your comments, tweets and face-to-face discussions regarding the previous posts on using iPod Touches in the classroom (part 1 / part 2). This blog post concentrates on the issue of using QR codes with a mobile device that doesn’t have a camera!
I met with a colleague from the Aberdeenshire iPod Development Group this week to share what we were doing and to see if there was potential to work together. They discussed an idea to use the iPods in an outdoor learning exercise and wondered about using QR codes to allow pupils to access educational resources while exploring a forest.
I’d also been reflecting on using QR codes within the school for an iPod treasure hunt and we had both realised that the lack of a camera on the iPod Touch 3G made this tricky. Tricky but not impossible. The BeeTagg Reader Pro app (currently free) can read QR codes (and other types) from the iPod Photo Library!
I had successfully tried this app before but wanted to know if I could put more information into the image containing the QR code. This would allow the pupils to be able to differentiate between them in the Photo Library. I tried adding some text underneath the QR code and transferred this image to the Photo Library.
It worked! However the text is a little difficult to read on the small screen, especially when you only have the smaller tile view of the Photo Library. So next I tried colour-coding the QR code images.
It worked as well! I imagine that colour-coded or labelled QR codes could be printed out and placed in appropriate locations (either in the forest or within the school. Or even within your classroom!). The pupils could match up the QR code to the ones pre-stored in the Photo Library and then access the material on their mobile device. This method also enables use of mobile devices with cameras, so has longevity if planned correctly. The material linked to the QR codes can also be modified without having to reprint the labels so resources can be tweaked to improve pupil learning at will.
There are more pressing concerns as to how the content will be stored on the iPods or accessed from within a forest (I imagine you’ll need a 3G signal for internet access unless you can set up some kind of adhoc wifi network in the trees!) but allowing pupils to access this content quickly means mobile devices already have a significant benefit to classroom teachers.
