QTI-FAR - A Framework and ARchitecture for Assessment Systems

Posted in

This project is about applying intelligent reasoning techniques in e-assessment systems. We have developed QTI-FAR - a framework for design and implementation of e-assessment systems based on the IMS Question and Test Interoperability (QTI) standard.  We call such systems QTI assessment systems, or just QTI systems. The framework is developed starting from the OMG Model Driven Architecture (MDA) software engineering standards. It includes a QTI metamodel (in UML and ECore) and model transformations for QTI assessment systems, as well as a QTI model repository that could be reused in implementation of other QTI models that an assessment expert may suggest in a specific assessment system. It also specifies an architecture for QTI assessment systems that is reusable, extensible, and facilitates interoperability between its component systems. QTI-FAR systems are QTI assessment systems implemented using QTI-FAR. A use case model for a simple choice example question in QTI-FAR system is shown here. Details about the DL reasoner used by this QTI-FAR system are shown in the RAS project.
