CBT & eLearning

“Through the Internet, education will become learner- and goal-oriented rather than faculty-centered”

Lesser, Klein, MIT

“eLearning should not be confused with traditional forms of CBT, which is nothing more than recorded education”

Drucker, Delphi Group

Computer Based Training (CBT)

Origin of eLearning Attempt to automate education

Process of learning predeterminated by: Time Place Content

If we intend to implement a real application: Better – CBT Tools

eLSE is a research project (not real application): We need eLearning Tools:

New architectures (service-oriented) Semantic Web, Semantic Grid

Standards – architectures, protocols, e-content, … ADL SCORM

Multi-communication access to information sources (mobile devices)

Agent-based approaches Knowledge technologies Application integration Profiling
