Lecture Notes in Computer Science- P101: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 | A Flow-Oriented Visual Language for Learning Designs 489 one place. This feature together with a carefully designed visual aspect should increase the usability of the notations with respect to more exchange-oriented ones such as IMS LD . The following subsections go inside the different notations which constitute the unified flow-oriented view. Notation for Describing Learning Objectives The notation for describing Learning Objectives is a diagram that allows the definition of the learning objectives to be covered in the UoL. In addition this notation can include the definition of which role will be involved during the achievement of the learning objectives. Each learning objective definition includes a verbose textual description which can be attached to the graphical representation. Fig. 1. Example of a learning objectives definition with role association Fig. 1 shows an example of this notation. This example contains two objectives OBJ 1 and OBJ2 represented with ellipses. In addition OBJ 2 is subdivided into a graph of sub-objectives using a dashed arrow. In the figure two roles have been defined STUDENT a learner role and TEACHER a staff role represented as stickmen. These roles are associated to learning objectives using lines between the stickman and the objective. It should be pointed out that the association between actors and objectives is inherited by sub-objectives which means that the role associated to the main objective also participates in the achievement of the subobjectives. In our example the TEACHER role is only involved in the achievement of OBJ and OBJ learning objectives while the STUDENT role is involved in OBJ 1 OBJ 2 and in all the sub-objectives of OBJ 2 . OBJ OBJ OBJ and OBJ . Note that it is also possible to design learning objectives for different learner roles because the notation for learning objectives is not restricted to only one learner role per diagram. 490 I.
