Lecture Notes in Computer Science- P28: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 | Modeling Units of Assessment for Sharing Assessment Process Information 135 2. A UoA provides a base for analyzing and evaluating an assessment plan by using formal techniques . validation and simulation for a deeper understanding comparison and improvement. 3. An executing UoA can scaffold learners tutors and other stakeholders to perform the tasks suggested by providing guidance and awareness information such as current status suggested next steps available resources and decisions . terminating activities and initiating a service . 4. An executing UoA can enforce learner tutors and other stakeholders to strictly follow a plan by configuring a workspace for carrying out prescriptive tasks . doing an examination with a QTI tool and demonstrating skills with a simulator by controlling and changing the sequence of activities based on the execution state and circumstantial information and by orchestrating the efforts made by different roles participants. For all these benefits to materialize APS has to match the following requirements derived from 14 15 1. Completeness The APS must be able to fully describe the whole assessment process which consists of various types of activities performed by various roles that use a variety of assessment resources. 2. Flexibility The APS must be able to express the assessment meaning and the functionality of the different data elements within the context of a UoA. It must be sufficiently flexible to describe a wide range of assessment strate-gies approaches. 3. Adaptability The APS must be able to describe adaptation aspects within a UoA so that the assessment resources and assessment activities within a UoA can be adapted to the preferences portfolio educational needs performances assessment results and situational circumstances of users. 4. Compatibility The APS must be able to match and integrate available standards and specifications such as the IMS and IEEE LTSC . In particular it should be
