1. Knowledge Forum® (KF): theoretical underpinnings of build-in features Johnny Yuen

2. Knowledge Building Discourses The 12 KB Principles (Scardamalia, 2002)

3. 12 KB principles (con’t)

4. Knowledge Forum® (KF) Online Collaborative Knowledge Building Platform (http://www.knowledgeforum.com) Current version: 4.8 Database format: ZooLibTuplebase (http://analysis.ikit.org/kfcoders/index.php/The_Tuplebase) Java (enhanced, lite) & html interfaces

5. Knowledge Forum: A user designed view Singletons Discussion Threads

6. Knowledge Forum: A user designed view Attachments Threads Singletons

7. Knowledge Forum: A Note

8. Knowledge Forum: A Note Problem of Investigation Scaffold Supports Note Content User defined keywords Selected Scaffold Supports

9. Analytic Toolkit for KF (ATK) Developed by OISE, IKIT. Stats appeared in KB related literatures. Individual Student/Class Statistics. Almost instant reports Welcome by teachers. Easy to understand & generate by average users.

12. Pitfalls of relying solely on participatory stats. for assessment Limited to note or view level statistics, lacking thread level analysis, time distribution Pitfalls of using participatory stats for assessing individual or overall KB discourse: High quantity not equals high quality (e.g. large number of “I agree” notes without progression in knowledge) Students may be hinted to act according to the assessment rules (e.g. open notes for the sake of higher read statistics, not really comprehending the notes)

13. KF Build-in Analysis Applets

14. Stats generated through exporting KF database into MySQL Database KF ZooLibTuplebase KF Exporter  MySQL  Re-build Thread Structure  Queries for flat table with participatory statistics , & add coding results from e.g. VINCA, like argumentative markers, question markers and so on… build secondary level tables, e.g. by Pivot Table in Excel or PASW(SPSS) Takes time! Requires technical skills, not open to all users More structured & meaningful data for generating feedbacks to pedagogical design, e.g….

15. Stats generated through exporting KF database into MySQL Database *Discourse Markers: Question markers, Argumentative markers, Content markers, Scaffolds

18. Summary Interpreting discourse participatory statistics alone might not be getting the whole picture Discourse participatory statistics PLUS other qualitative indicators may reveal more in-depth scenario KF®MySQL has made great progress in terms of KF® data manipulation Our goal: an online analysis platform that even teachers with no technical background are able use to evaluate their KB classes Starts from sketch, has lots to build (the platform, plug-in modules) before teachers can use it on their own
