Kevin Hall and Mike Crosson are based at Wintec and have been piloting QR codes and video clips in trades training - partly to encourage students to do some revision. QR codes are described in Wikipedia as "A QR Code is a matrix barcode (or two-dimensional code), readable by QR scanners, mobile phones with a camera, and smartphones". The idea is that it makes it easier for students to access and use conent on online courses.
The speakers demonstrated live how to create a resource in Moodle and an associated URL (and how to create a much shorter link by also using Tinyurl). All content has been trialled in advance to make sure that it is mobile compatible. The benefit for students is that they don't have to mess around trying to get a URL ' perfect', and makes it really easy to grab a link from (with) a mobile phone.
