It seems that paper.li is gaining momentum. This is an online paper and free to sign up. I am thinking of creating a class paper using this site, take a look and whilst there, check out these:
At the start of each term I try to pick one or two online tools to add to my growing knowledge. Whilst I know it is not new, and I am probably the last to use it - http://delicious.com I think is brilliant! I have created a stack which has a collection of educator blogs called: Innovative educator blogs. It is a great way to bookmark sites and I like the visual element.
Awesome Screen Shot (found in the Chrome Web Store - free) is brilliant you can take a screen shot and then annotate it before saving it on your computer.
So that's 2 tools I am using and it is only day 2 into term 4, off to a good start!
