Lecture Notes in Computer Science- P102: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.

As an example of UoL authoring Fig. 7 shows an excerpt of the visual specification diagram corresponding to the Learning to listen to Jazz UoL. This is a relevant example involving IMS LD Level B features since it addresses adaptability based on student decisions and actions. This example also provides a simple learning style evaluation which is incarnated in how the learning path best suited for the learner s style is recommended by the UoL. In addition the example shows how the progress on the UoL is based on the result of the work that is done in the activities. Fig. 7. Excerpt of the Learning to Listen Jazz UoL diagram with the e-LD notation 4 Conclusions and Future Work In this paper we have presented an EML visual notation specifically oriented to simplify UoL authoring. However it is important to note that we are not promoting yet another new EML. The key idea is to use this author-oriented notation for the authoring process and then translate the designs to the more machine-oriented notations of standard EMLs . IMS LD through importation exportation processes. As a result of the preliminary experiments we think that the graphical notation proposed simplifies the process of authoring UoLs. The creation of UoLs of the complexity of those analyzed in our practical experiments is a feat beyond the reach of most designers but students without a previous background in using EMLs were able to recreate them using e-LD. However further study is required especially in reuse scenarios where non-experts create new UoLs based on UoL templates or previously built UoLs. A Flow-Oriented Visual Language for Learning Designs 495 Readers familiarized with the UML graphical notation will notice several parallelisms with the notation described in this work. This is intentional given the background in Computer Science of the participants in the test case. However different notations can be developed or customized for a particular stakeholder or .
