ICWL 2010 in Shanghai

  1. 1. Delivering QTI Self-tests to Personal Learning Environments using Wookie Widgets<br />Vladimir Tomberg, Raido Kuli, Mart Laanpere, PeeterNormak<br />Tallinn University<br />Estonia<br />09.12.2010, ICWL 2010, Shanghai<br />1<br />
  2. 2. Personal Learning Environments <br />The shift of PLE pedagogical paradigm: from teacher-driven to self-directed learning process<br />Web 2.0 technology is causing a decrease in the use of existing digital content, which is still valuable and re-usable<br />2<br />
  3. 3. PLE and Tests<br />Questions and tests are digital learning objects, which currently can be hardly delivered to PLE<br />But there is a wealth of valuable, reusable questions and tests stored in learning object repositories<br />3<br />
  4. 4. IMS QTI XML: de facto standard for assessment-related content<br />Since 2005 QTI ver. 2 is stable and widely used (but still is beta!)<br />Possibility to import/export tests<br />Testing system as a set of tools or services:<br />authoring tool, <br />repository, <br />test construction tool, <br />assessment delivery system<br />4<br />
  5. 5. Widgets technology<br />Lightweight Web applications designed for a single specific function<br />Great choice of different widget platforms and related specifications not compatible between themselves<br />First standard: W3C Widget Packaging and Configurationspecification (2006)<br />5<br />
  6. 6. Our scenario for Self-Testing in PLE<br />Teacher embeds selected self-tests into her/his blog in form of widget<br />Embedded search tool provided to learners for finding suitable self-tests from repository <br />Students generate self-test by themselves<br />6<br />
  7. 7. Functional Requirements<br />Searching a suitable test from a repository<br />Visualization of testing questions and submitting the test<br />Receiving results of test’s completion with feedback<br />7<br />
  8. 8. Overall Architecture of Software Solution<br />To implement the embedding widgets into blogs we used Java servlet server Apache Tomcat, which serves several web services and software: Wookie application, QAPS API and question rendering engine R2Q2.<br />8<br />
  9. 9. QAPS<br />QAPS (QTI Assessment Proxy Service) is API, which deals with self-test related data exchange between a Learning Object Repository and the Widget engine.<br />9<br />
  10. 10. Using QAPS API for Self Testing Solution<br />10<br />
  11. 11. Workflow for QTI player prototype components<br />11<br />
  12. 12. Widget at Work: Searching for Test<br />12<br />
  13. 13. Widget at Work: Implementation of Test<br />13<br />
  14. 14. Widget at Work: Finishing Test<br />14<br />
  15. 15. Widget at Work: Feedback<br />15<br />
  16. 16. Conclusion<br />The implementation of QAPS demonstrated the feasibility of re-using the existing QTI content stored in Learning Object Repositories<br />Project source code address:http://trac.htk.tlu.ee/modules/wiki/qti_player<br />16<br />
  17. 17. To Do<br />Adding authentication<br />Service, which is going to aggregate the learners’ profiles, and store their tests’ results<br />17<br />
  18. 18. Thank you.<br />18<br />
