Lecture Notes in Computer Science- P30:This year, we received about 170 submissions to ICWL 2008. There were a total of 52 full papers, representing an acceptance rate of about 30%, plus one invited paper accepted for inclusion in this LNCS proceedings.

IMS Question and Test Interoperability QTI is an e-learning standard supporting interoperability and reusability of assessment tests items. However it has insufficient expressiveness to specify various assessment processes especially the new forms of assessment. In order to capture current educational practices in online assessment from the perspectives of assessment process management we extend QTI and IMS Learning Design LD with an additional layer that describes assessment processes in an interoperable abstract and efficient way. Our aim is an assessment process specification that can be used to model both classic and new forms of assessment and to align assessment with learning and teaching activities. In this paper the development of the assessment process specification and its benefits and requirements are described. A conceptual model the core of the assessment process specification is presented. The proposed conceptual model has been subject to a first validation which is also described.

QTI addresses those assessment types for which an unambiguous definition in technical terms can be specified such as multiple-choice and filling-in-blank. In addition QTI provides sufficient flexibility to grow into the advanced constructed-response items and interactive tasks we envisage as the future of assessment 1 . Recently many QTI-compatible systems and assessment items have been .
