IMS QTIEngine on Android to Support Mobile Learning and Assessment

The IMS Question and Test Interoperability (QTI) specification defines a standard for representation of assessment content and results, supporting the transfer and delivery of these materials in multiple IT systems. The ability to import test items and assessment results in mobile contexts offers greater flexibility and interactivity for learning and teaching. Recent mobile devices provide a platform on which more complex applications can be implemented and therefore have the potential to be used as powerful learning tools, both offline and online. In this paper, we describe a mobile QTI rendering architecture and tools built on top of the core software library of “ASDEL” to deliver an assessment consisting of an assembly of QTI items and to retrieve assessment results. A mobile QTI engine was deployed upon an Android system and provided services for rendering and processing QTI XML. It allowed learners to play QTI items natively and receive feedback effectively which enabled better support for offline mobile learning.
