Motivation

• Businesses spend up to 100 billion each year to
  train workers. Yet estimates are that less than
  10 of this training transfers to the job. So
  business wastes 90 billion each year....
  
• Review on US training effectiveness (Detterman
  1993)

School vs Workplace Learning
3
Identified Learning Processes

• Reflection-in-action (Schon)
• Domain Construction (Sumner)
• Perspective Taking (Boland Tenkasi)

4
RichODL

• Application of Enrich to modelling and simulation
  of dynamic systems (e.g. fluid, electrical,
  mechanical) for traditional and distance learning
  
• Facilitate reuse of simulation models
• Enable SMEs to carry out simulation of dynamic
  systems
• Simulation tools are expensive
• Simulation knowledge is scarce

Summary (1/2)

• Workplace learning not the same as school
  learning
• reflection-in-action, domain construction,
  perspective taking
• Knowledge Representations
• informal structured (text, diagrams, discussion
  spaces)
• formal (ontologies and knowledge bases)
• artifacts (models as MatLab simulations, VRML
  etc)
• Ontology Tools
• OCML - operational knowledge modelling language
• WebOnto - web based knowledge model
  browsing/editing tool
• Lois - query interface automatically generated
  from the ontology
