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)

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/

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

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

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
