During my blogging hiatus, which corresponded with my move to the Canadian Polytechnic where I now am employed and a subsequent maternity leave (identical twins!!), I was jotting down on a post-it note new tools that I thought would be useful for instructors and students, but needed more time to explore. I came back to a very tidy cubicle (thank you tidyers) but no post-it. I’m trying to recall some of those tools, and bubbl.us came to mind. I remember liking bubbl.us because like my old standby, Gliffy, it passed the 2 minute test and the drag, drop, click interface works nicely. But bubbl.us is definitely more suited to concept mapping, since connections between ideas are automatically drawn . In the past I’ve taught an online distance course where a student assignment was to submit and share a concept map–we used CMap for this purpose, but it wasn’t as seamless as we had hoped. Bubbl.us would be a good replacement–a quick visit shows that the interface is even more intuitive than before, and the ability to collaborate with others (something we love to do in our constructivist-designed online courses) is a huge plus. The usual import and export features are there, and although I haven’t tested those recently, I’m pretty confident they work quite nicely–at the very least, it’s easy to find.
