Implementing SCORM: Icodeon SCORM Player
• Since 2005
• Integrated into e-learning systems, LMS
Trend 2008-2009:
SCORM use is
increasing.

The Player applications enable vendors of e-learning systems to
rapidly add the full feature set of e-learning standards.
SCORM Run Time Environment
• Content uses a
SCORM API that must
be added to the
browser.
• Tight integration
between content
availability and content
sequence.
• User interface
controls specified by
SCORM replace
standard browser
devices.
… SCORM requires tight coupling between content & run time environment

Free the Content?
SCORM based content is
“trapped” because:
• tight coupling between
content and environment
• content does not use
standard browser devices
for common internet
functions
Does IMS Common Cartridge really “Free the Content” ?
1. SCORM – one way in which
content can be “trapped”
2. The Icodeon Common Cartridge
implementation
3. IMS Common Cartridge –
evaluating the claim to “Free the
Content”
Both SCORM and IMS CC Use Packaged Content

IMS Common Cartridge can be implemented to break the coupling between
content & environment, and to use standard browser devices.

The cartridge content can be more or less “free” – this depends more on
the technical implementation than on the technical specification.
