Elearning in the semantic age

1
Elearning in the semantic age

• Emerging web technologies provides exciting new
  posibilities.
• Standards focusing on semantics rather than
  syntax provides durable and extensible methods
  for data integration.
• Open source and open standards, reuse and
  evolution will given time and a framework to
  compete in give rise to a rich learning
  environment.

Our vision

• Lerner motivation is crucial, a learning
  environment need to be inspiring and trigger
  curiosity.
• Content managementCourse/content creation,
  portfolios, profiles, annotations, etc.
• Knowledge navigationSeparation of content and
  context
• Experience-oriented environmentsVirtual
  communities, 3D-environments

Three problems with current approaches

• Teaching models remains unchanged
• Canned books / taped lectures
• Email correspondence school
• Multiple choice test
• Perspective on metadata is too limited.
• Definitive instance
• Diversity
• Monolithic proprietary systems will not easily
  adapt to new standards

Proposed solutions

• Learner-centric educational architectures
• Knowledge Manifold / Conceptual
  WebInterest-based knowledge pulling
• Semantic Web layer
• A distributed metadata language RDF. Achieving
  semantic interoperability, extensibility and
  reusability are some of the goals.
• A Learning Framework
• A layered open architecture where independent but
  cooperating applications present the user with a
  smorgosbord of learning offerings.

Anyone can say anything about anything

• SW-techniques allow you to add metadata to
  distributed resources just like html allows you
  to link to such resources.
• Metadata is not bound to a fixed description
  format (schema), i.e. you may invent a
  description format of your own.

6
Things you can do with SW

• Express metadata about remote resources
• Add personal annotations
• Extend content, versions may split, evolve and
  merge
• Certify resources

7
Introducing the Learning Framework

• Not monolithic
• Layered open Architecture
• Pluggable architecture
• Open Standards
• Open source
• Simplify
• Metadata exchange
• Application development
