We’re fortunate enough to have a number of iPads, which are centrally managed by our IT department. That’s great, except for when we have special projects that require the students to access specific websites. It’s too time consuming to have our IT department add web links for a short project (and, let’s face it, it’s entirely likely that we need those links available pretty quickly – too quickly to go through IT). Rather than worry about getting the web links on the iPads, we just generate QR codes for them and have the kids use the QR code reader on the iPad to get to the site. It seems obvious, now that I’ve written it out, but it, um, took us a while to figure that out.
