Q: From what you've seen in the field, what's the most interesting instructional use of mobile devices happening now?
Keren-Kolb: Definitely what's going on in Australia. Teachers are using QR (two-dimensional bar codes) for activities and learning. In the United States, about 60 percent of the phones can do this, but in most other countries, it's almost universal. So, in some Australian schools, this means [that] students come in on the first day of class and their entire syllabus is on a bar code they scan directly into their phone—same thing with some books and homework assignments. They'll scan a code for their homework, and it'll link to video tutorials and activities. So, moving away from textbooks and moving toward paperless learning that's much more interactive. I think that's exciting—how much information you can attach to that little bar code, and use it to extend learning.
