1 A QTI Management System for Service Oriented ArchitecturesTenCompetence Open Workshop, Manchester, 11th-12th January 2007 A QTI Management System for 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 A QTI Management System for Service Oriented ArchitecturesTenCompetence Open Workshop, Manchester, 11th-12th January 2007 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 A QTI Management System for Service Oriented ArchitecturesTenCompetence Open Workshop, Manchester, 11th-12th January 2007 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 A QTI Management System for Service Oriented ArchitecturesTenCompetence Open Workshop, Manchester, 11th-12th January 2007 General structure 1 XHTML APIS 2 Assessment item (XML file) Feedback Browser

5 A QTI Management System for Service Oriented ArchitecturesTenCompetence Open Workshop, Manchester, 11th-12th January 2007 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
