Improve Knowledge Referencing
IMS-LD is a progress in eLearning specifications– Some IMS-LD scenarios cannot be expressed in
SCORM– IMS-LD is more general, favors innovative methods
Assigning optional objectives and prerequisites according to the IMS RDCEO specification (IMS 2002) is not enough– Consistency checking is not supported between levels nor
between the content of learning activities and resources, and the actors’ competency
– Knowledge in learning resources is not described – Actor’s knowledge and competencies is only indirectly defined
through educational objectives Need for a qualitative structural representation of
knowledge in activities, but also a quantitative one

Structured Competencies
To say that somebody needs to acquire a certain knowledge is insufficient
A skills’ taxonomy based on different viewpoints : instructional objectives, generic tasks/processes, meta-knowledge Expandable taxonomy from general to
specific Ordering skills from simple to complex Integrating domains of multiple
intelligence: cognitive, affective, social, psycho-motor

Referencing PrinciplesReferencing Principles
1. Tree organization of the knowledge referential: – allows competence inheritance from parent node to children– reduce significantly the mechanisms of competence
analysis and management. 2. Must be completed by relational logic to sustain
more refined mechanism of conceptual matching. 3. Ontology referencing is insufficient without mastery
levels– prevent coarse granulation of sense– weak semantic management services.
4. Quantitative measures to weight ability on knowledge – level scale to be reasonably simple, manageable – levels correspondomg to clearly identify cognitive processes– to be materialized as a learning design
