- Aggregate content based on LT specifications- Low level of abstraction- Mostly driven by the LT tags

Proposal of an abstract layers stack and a

design model

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


5

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).

Describing tasksDescribing tasks

• Tasks depeding on the kind of outcome (text, file, jme, latex,..)

• Not yet collaborative tasks


16

Some conclusionsSome conclusions

• Authoring educational content can be improved by means of abstraction

• A 2-axis based abstraction model– Modelling instructional knowledge domain– Modelling instructional template (learning

design)

• Some future work is possible…

Integrating SW for e-learning Integrating SW for e-learning with web 2.0with web 2.0

• Domain models and instances are growable by the social web

• Content material can keep semantic labels form conceptualizations

• Social rating can provide metadata
