Diigo

Though I am having some trouble figuring out how to use diigo I do see it's educational applications.  What an easy way to store websites for a lesson, especially a webquest!  And you can easily point out what it is you want to kids to notice.  It's also a GREAT way to teach them to evaluate web resources because it makes their thinking process visual.  You can ask them to skim and highlight (inquiry skills!) and then see if they understand by seeing what they've done.  You can ask them to sticky note a specific number of facts and then review to see that they are choosing the best info.  It also saves on a lot of paper and would be completely engaging to kids!  And they could work on it at home if there's an issue with computers in the library and you could still see their thought process!
