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”

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