Collaborative Web Page Annotations With Diigo

After introducing students to the concept of annotating their sources, the instructor describes Diigo. Diigo is an add-on for Firefox (a more limited add-on is available for Chrome, but the Firefox add-on is used for this activity). It allows for real-time collaborative annotation of text on web pages. Users may highlight text, add sticky-note annotations to specific highlights, or add floating notes to any web page. Diigo also provides a bookmarking & caching function to store pages on diigo.com servers to mitigate against digital impermanence. Teachers may sign up for an educator account which provides access to group administration features useful for working with a group. Users within a group, for instance, can share annotations with each other without making them publicly available to all Diigo users.

As students are introduced to Diigo's functions, they should sign up for an account on the website. Teachers choosing to work with a Diigo group can add students to the group, or users can make their annotations public to share with the group.

Once set up, students work in pairs to annotate a page selected by the instructor responding to questions relevant to the goals of the course (in this case evaluating how accurately discussants in a discussion thread summarized each other).  Students highlight text & add sticky notes with their responses.  After students are done, the class reviews the annotations as a group.
