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/

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 Search
