Recently for my educational technology class, we were instructed to use Diigo to bookmark different webpages that would be beneficial to us later as educators or even now as we are training to be educators. This is a great way to be able to collect ideas, and come back and find them using the tags.
One of my favorite new findings is the following website http://www.schrockguide.net/bloomin-apps.html. This website is so great! This takes Bloom's Taxonomy to a whole new level. Many schools are incorporating iPads into their daily lessons. This website has great app recommendations that are categorized according to which Bloom's category fits best. Very cool! I also found a lot of blogs that teachers have posted with so many printables and freebies. Diigo will make it convenient to come back to these blogs.
