An ortogonal view for authoringAn ortogonal view for authoring
• Conceptualization– Knowledge domain ontology– Learning design abstract model (visual
languages for LD) or instructional templates
• Instantiation– Topic map based on a given ontology– LT-based content with references to LOs

Ontologies in e-learningOntologies in e-learning
• Entities and relationships within knowledge domain
• Axioms, rules and constrains of the entities of the ontology
• Allow content interoperability at a “knowledge level” (A. Newel, 1982)

Structure vs. Knowledge domainStructure vs. Knowledge domain
• Knowledge domain– Based on instructional ontologies– Growable and maintainable– …Ready for Web 2.0!
• Structure and Learning Design– Different templates for different purposes– Integrate activities– Content retrieved using high level queries

Levels of abstractionLevels of abstraction
Content level: retrieve, embed or links to the appropriate LO. We consider only a low granularity component at this level.
Structure level: provide hierarchical decomposition of the learning environment. This level provides an explicit description of the table of contents that can be incorporated to the information model.
Task level: definition of learning processes, collaborative activities and grading type.
Sequencing level: Scheduling of modules and tasks, time restrictions and instructional dependencies between modules.
Management level: considers interoperability issues between learning content and virtual learning environment (VLE).
