Diigo: Once they start their web-related search, Diigo, an add-on extension for Firefox and Internet Explorer, allows students to highlight text and post sticky-notes directly onto webpages, then share their comments within the group. Others can add their own comments to the note. Selected text is archived to a "my bookmarks" page, along with the comments and a copy of the website. Students can collaborate within the bookmarks site or on the individual websites. Diigo supports RSS feeds, allowing teachers to follow student progress. The more I use this tool, the more I'm convinced it ought to be integral to every research project. It allows students to actively connect with the information they're reading--to question, annotate and infer. All in collaboration with their group. How amazing is that???
