Sharable Content Object Reference Model (SCORM) is a collection of
standards and specifications for web-based e-learning. It defines
communications between client side content and a host system called the
run-time environment (commonly a function of a [[learning management
system]]). SCORM also defines how content may be packaged into a transferrable
ZIP file.
SCORM is a specification of the Advanced Distributed Learning Initative, which comes out of the Office of the Secretary of the Defense.
SCORM 2004 introduces a complex idea called sequencing, which are rules that
specify the order that a learner may experience content objects.
The standard uses XML, and it is based on the results of work done by
AICC, IMS, IEEE, and [[Ariadne
(software)|Ariadne]].
Conformance
A testing initiative was started in 2003.
Avilar's WebMentor LMS was the first
to receive SCORM certification on February 12, 2003. In December 2004, the
US Department of Defense mandated that all its e-learning purchases must
conform to SCORM standards. By August 2005, ADL had validated 178
SCORM-conformant products.
SCORM versions
SCORM 1.0
The original version. Proof of concept only. Introduced the notion
of Sharable Content Object (SCO) and the API model in which the burden of
managing communication latency across the Internet is handled by the runtime
environment, not by the content objects.
SCORM 1.1
The first production version. Used an Course Structure Format XML
file based on the AICC specifications to describe content structure, but
lacked a robust packaging manifest and support for metadata. Quickly abandoned
in favor of SCORM 1.2.
SCORM 1.2
The first version with a real conformance test in the form of a
test suite. Uses IMS Content Packaging specification with full content
manifest and support for metadata describing the course. Also allows optional
detailed metadata tagging of the content objects and assets described in the
manifest. Usually works well; both the delivery system and content pass the
test suite without cheating, but lacks sequencing and some other desirable
features. No longer maintained or supported by ADL.
SCORM 2004
The current version. Based on new IEEE standards for API and
content object-to-runtime environment communication, with many ambiguities of
previous versions resolved. Includes ability to specify adaptive sequencing of
activities that use the content objects. Includes ability to share and use
information about success status for multiple learning objectives or
competencies across content objects and across courses for the same learner
within the same learning management system. A more robust test suite helps
ensure good interoperability.
