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???

Somehow find a way to use Diigo to assess student web-log writing without defacing the students' "intellectual property" and turning writing into "schooliness."

My students have joined the Group. Now when they go to their web-logs, after logging in to their Diigo account and setting "Show Annotations > Show Group Annotations" on their Diigo toolbar, they will see the highlights of specific passages from their writing that I have left (and I can start students doing this too, it occurs to me in a very attractive flash), and my annotations will pop up on their screen when they hover their mouse over the highlights.Also good, our Diigo Groups Bookmarks page records all highlights and annotations I have made on one page. Students can use that to see all feedback I have given to specific strengths and weaknesses on all students writings.And since they're using anagrams instead of first-name usernames on their blogs, there's less of a chance of any embarrassment resulting from this "public feedback"--with "invisible ink."

Web 2.0 services are generating what is truly a personal learning renaissance.Here's a comment from teacher Elizabeth Davis at Classroom 2.0:"Following and reading blogs, participating in ning, contributing to wikis, writing in my blog, I haven't thought this much in years. It truly is an amazing phenomenon. I feel so intellectually alive. I'm inspired and challenged constantly. The blogs I read lead me to question and explore new tools and Websites. I haven't written this much since I was in school. It is all so exciting and energizing. For me, classroom 2.0 could just be about my own growth and learning and that would be enough."A good example of a free Web 2.0 service is Wikispaces. Here's a class wiki made with the service - A Broken World, the World War I wiki of a Grade 9 class. Their teacher comments:You are now "textbook writers." Your goal is to make a better, more interesting textbook than that overweight, boring, 20th Century history textbook you're now using. And to do work of such high quality that you can include it on your resume as another example of your academic skills in your "digital portfolio."Here are some other School 2.0 online services:* Diigo- for "social bookmarking" of Web sources.* Blogger - to create a class weblog.* Ning - to build your own social network]

I just finished teaching a computer ethics course at Judson University--okay, it's still Judson College now, but they will be changing to University this Fall (www.judsoncollege.edu). I used a web 2.0 tool called diigo (www.diigo.com). Diigo is an acronym for "Digest of Internet Information, Groups and Other stuff".It may be that you've heard of del.icio.us which is a very popular social bookmarking tool. Diigo is a social bookmarking tool plus annotation tool. It allows you to read an article, bookmark it, and within the article, make annotations like "highlighting" and "sticky note comments". This makes it an awesome research tool.In the past I have had students bring articles to class that pertain to the assigned chapters, but this time I made this an entirely digital activity. The students were to find online articles, book mark, annotate, and share them with the group forum that I set up for them. We then, with the group forum on the projector screen, would have each student talk us through their article.While this tool is still in "beta" the student assessment survey that was taken at the end of the last class seemed to indicate that this activity was well received.
