TAILIEUCHUNG - Lecture Notes in Computer Science- P32

Lecture Notes in Computer Science- P32: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. The authors of these accepted papers | 142 Y. Miao P. Sloep and R. Koper concept support-activity in LD. An assessment process model based on APS can be transformed into an executable model represented in LD and QTI. Thus we should be able to use an integrated LD and QTI run-time environment to execute various forms of assessment based on APS. In addition APS will be organized using the IMS Content Package specification. It can use IEEE Learning Object Metadata LOM to describe the meta-data of elements in APS. Moreover the IMS Reusable Definition of Competency or Educational Objectives can be used to specify traits and assessment objectives. The IMS ePortfolio can be used to model portfolios coupled with artifacts in APS and integrate a portfolio editor. The IMS Learner Information Profile can be used to import global properties from a run-time environment and export them to it. IMS Enterprise can be used for mapping roles when instantiating a UoA. Therefore APS is compatible with most existing relevant e-learning technical specifications. 5 Conclusions and Future Work This paper addressed the problems one faces when attempting to use QTI and LD to support the management of assessment processes in particular formative assessment and competence assessment. In order to support the sharing of assessment process information in an interoperable abstract and efficient way we developed APS as a high-level assessment-specific process modeling language. We have developed the conceptual model of APS by adopting a domain-specific modeling approach. The conceptual model has been described through detailing the semantics aggregation model the conceptual structure model and the process structure model. The first validation study has been conducted through investigating whether the conceptual model of APS meets the requirements of completeness flexibility adaptability and compatibility. The results suggest that the model does indeed do so. APS should meet additional requirements . reproducibility formalization and
