Some of my favourite online learning tools...
Okay, here's a brief list of some of the ones that I'm playing around with at the moment:
Prezi - great little slideshow software completely web-based.
xTranormal - great fun text-to-speech application. Again, completely web based, though you do have to sign in.
Dropbox - allows submission of work online!
And I can't go past Google Docs, either. Great for collaborative writing.
I tried to include some links, but it triggered the spam filter. Should be easy enough to find by doing a search, anyway.
