  • 9. 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

  • 21. Open source
  • 22. Lessons learned
  • 23. 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
  • 24. 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
  • 25. 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)
  • 26. Only Recent Items are Stored in the Syndication Feeds • Blogger feeds contain 25 most recent items • WordPress feeds contain 10 most recent items
  • 27. Conclusions and future work
  • 28. User testing • User testing in Tallinn University: 4 courses running • Think aloud usability testing
  • 29. Future work • Aggregating recent content from various Web 2.0 services • Providing visualization widgets for external web sites • Archiving the course posts and comments
  • 30. Ideas • Using EduFeedr visualizations for centralized/ closed LMS • Using EduFeedr for TEL researchers’ blogs
