Marginalia (http://www.geof.net/code/annotation/) is an award-winning open source Web annotation tool integrated into Moodle discussion forum. It allows users to highlight passages of text and type notes in the margin of a post, as with a paper book. Furthermore, a user can choose to share the notes with others in a forum. By making annotations in a discussion forum, participants are better able to mark up points for follow up, summarize the dialogue, and make further contributions based on what they have read. This presentation describes the design of Marginalia, explains the pedagogical considerations behind its design, illustrates how it can be used in online classrooms, and shares our initial research findings.
