  1. A QTI Management Systemfor Service Oriented Architectures Josep Blat, Toni Navarrete, Ayman Moghnieh, Helena Batlle (Universitat Pompeu Fabra) TENCompetence Open Workshop on Service Oriented Approaches and Lifelong Competence Development Infrastructures Manchester, 11th-12th January, 2007

  2. Introduction • QTI (Query & Test Interoperability) is the IMS specification for assessment • Last versions: • QTI 2.0: items (questions) • QTI 2.1: tests • Need for open source service-based implementations: • Authoring tools • Management systems (engines/players)

  3. APIS engine • Assessment Provision through Interoperable Segments • Supports QTI 2.0, but only some types of interaction (types of questions) • Web Services-based interface Developed by University of Strathclyde • JISC Project: • http://www.jisc.ac.uk/whatwedo/projects/apis.aspx • Available at SourceForge: • http://sourceforge.net/projects/apis/

  4. General structure Assessment item (XML file) Browser Feedback 2 XHTML APIS 1

  5. Objective of our work • Extend APIS to support: • More interactions types (types of questions) • More datatypes (of variables) • More types of expessions (to obtain the corresponding result) • Assessment tests (QTI 2.1): • Internal structure of tests: sections and parts • Processing the outcome for the whole test

  6. New interactions (types of items) Associate Interaction Gap_match Interaction

  7. New interactions (types of items) Match Interaction Order Interaction

  8. INTERACTION TYPE IMPLEMENTED NOT IMPLEMENTED New interactions (types of items)

  9. New interactions (types of items)

  10. New supported data types IMPLEMENTED NOT IMPLEMENTED

  11. IMPLEMENTED NOT IMPLEMENTED New supported expressions

  12. Support for assessment tests (QTI 2.1)

  13. SourceForge project http://sourceforge.net/projects/newapis/

  14. Demo http://193.145.45.154:81/

  15. Future work (I) • Integration of assessment into learning activities • Integration of new APIS with SLED (through CCSI) • Integration of assessment tests in the workflow of LD Units of Learning • Determining different learning paths according to assessment outcomes Source: SLED website http://sled.open.ac.uk/web/tech/ccsi.jsp

  16. Future work (II) • Development of a graphical editor of items and tests for QTI 2.1 • Previous work: QAEd for QTILite, which also provides other functionalities: • Management of a bank of items • Classification of items • Search • http://gti.upf.edu/leteos/newnavs/qaed.html
