    • Problem
    • How to follow and support learning activities which cross the borders of different Web 2.0 applications?
    • Vision
    • Requirements and limitations • support for all major blogging platforms using open standards (RSS, Atom, trackback, pingback) • no special plug-ins should be required on the student blogs • the scope of EduFeedr is limited with aggregating and annotating the feeds from both teacher’s and students’ PLE’s and visualizing the process of knowledge building • only teacher has an user account in EduFeedr, which allows her to modify the EduFeedr settings • anyone has read access to aggregated course content

    • Design methodology
    • Design methodology • Lightweight prototyping • Scenario-based design • Participatory design sessions • User stories • Paper prototyping
    • Current implementation of EduFeedr
    • http://www.edufeedr.net
    • Downloads • OPML file with blog posts feeds • OPML file with blog comments feeds • vCard file for Address Book • Tab separated file with social network data
    • Technical implementation
    • Blogs User Crontab initiated aggregation of REQUEST with credentials content EduFeedr EduSuckr front-end WSDL / SOAP back-end service RESPONSE with data MySQL / MySQL InnoDB
    • Development platform • EduFeedr is developed as Elgg plugin • SimplePie PHP library is used for aggregating feeds • JSViz JavaScript library is used for social network visualization • NuSOAP toolkit for PHP
    • Open source
    • Lessons learned
    • Locating the Comments Feed • Comments feed location is not always specified in the web page • Currently we support only Blogger and WordPress • Possible solutions: - Specifying the comments feed location for major blogging platforms - Adding the comments feed manually
    • Linking Student Posts with the Assignments • Methods - Link to the assignment post in the course blog - Assignment deadline - Asking from the facilitator • In the first course 10 posts from 91 contained the exact link
    • Linking Comments with the Participants • URL in the comment metadata is used to link the comment with a participant • Comment meta URL’s in the first course (100 comments): - participants’ blog in the course (3) - Blogger profile URL (57) - URL in the WordPress user profile (18) - OpenID URL (7) - No URL (15)
    • Only Recent Items are Stored in the Syndication Feeds • Blogger feeds contain 25 most recent items • WordPress feeds contain 10 most recent items
    • Conclusions and future work
    • User testing • User testing in Tallinn University: 4 courses running • Think aloud usability testing
    • Future work • Aggregating recent content from various Web 2.0 services • Providing visualization widgets for external web sites • Archiving the course posts and comments
    • Ideas • Using EduFeedr visualizations for centralized/ closed LMS • Using EduFeedr for TEL researchers’ blogs
