Understanding standards

Why standards

There are a number of standards, specifications, recommendations and "wannabe standards" that apply to learning technology. Conformance with standards can dramatically reduce the cost and time to specify, design and deploy learning technology solutions. For example, if content conforms to SCORM, most of the cost of integration of the content with a learning management system is eliminated. The ROI is higher for content developers as well as for the enterprise that uses the content, and the time to deployment can often be reduced from several months to a few minutes. Other standards and specifications that have become de facto standards exist or are being developed for metadata (data that describes learning resources or content), for learner information, to describe an individual's special needs for accessibility, to describe a competency or learning objective in a generic way, for competency records, and so on.

The bottom line is this: The judicious application of the relevant standards can save a lot of time and money.

Standards can be a challenge

Standards are thus extremely valuable, but they can be difficult to interpret without guidance, and they are not all equal in quality or relevance. In fact, some of them may be obsolete or demonstrably flawed, but are still being referenced and promoted to preserve existing investments, or sometimes because of simple ignorance. The ideal standard meets real world requirements, is economical to implement, and guarantees interoperability because every aspect of conformance can be verified. Sometimes, poor quality in a standard means that there are ambiguities that interfere with interoperability, or that it contains so many features that implementation is too expensive, or that it is so complex that full conformance is not verifiable.

Sometimes, standards can get in the way. At that point, one has to reconsider. Sometimes there is just no workaround but the business demands conformance. Sometimes conforming to the standard is just not worth it. But often all it takes is a new, creative approach to the problem to allow the functional and learning design goals to be achieved, while still conforming to the standard. This, in turn, requires experience, deep knowledge of the features supported in the standard, and the ability to look at all aspects of the problem with a fresh eye. This is why bringing in a consultant for as little as a few hours can pay off handsomely. Of course, this consultant should be independent and open-minded. If the consultant is suspiciously pushing a particular product or vendor, get a second opinion.

What makes a standard?

The ideal path to standard development is well ordered:
Practice -> recommendation or specification -> validation in the field -> accredited standard
Some recommendations or specifications never make it to the standard stage, but are nonetheless in such wide use that they become a de facto standard. Much of the Internet is built on such recommendations and specifications from the World Wide Web and the Internet Engineering Task Force, and learning technology standards often reference some aspects of those also.

Standards initiatives

Some standards initiatives applicable to learning technology include:

IEEE Learning Technology Standards Committee (LTSC)
The IEEE Learning Technology Standards Committee (LTSC) is chartered by the IEEE Computer Society Standards Activity Board to develop accredited technical standards, recommended practices, and guides for learning technology. Standards developped by the LTSC include metadata for learning objects (LOM), content object to LMS communication interface, content object to LMS communication data model, and so on. Any any individual with a direct and material interest may participate.

Advanced Distributed Learning (ADL)
A government sponsored initiative in partnership with industry and education. Publishes SCORM, the "Shareable Content Object Reference Model", a set of application profiles for interoperable learning content that can be launched and tracked by any conformant learning management system, using common web browsers. SCORM incorporates several other standards and specifications into a coherent model, and provides a test suite to verify conformance. SCORM was designed from the ground up to support global enterprises and to provide robust packaging, and has gained considerable acceptance around the world. An updated version, SCORM 2004, adds rule-based sequencing and a way to work with objectives that were missing from the previous version, SCORM 1.2. Both versions will probably coexist for quite a while, because SCORM 1.2 is simple and relatively inexpensive to implement, while SCORM 2004 conformance requires much more effort from implementers. However, since SCORM 1.2 is no longer supported by ADL, any new project should be based on SCORM 2004. ADL also promotes research on other standards, such as global identifiers for learning resources, repositories, simulation and collaboration, and so on.

IMS Global Learning Consortium
An international consortium of learning technology stakeholders from academic institutions and the enterprise world, that develops and publishes a number of specifications such as metadata profiles, learner information package, content packaging, content sequencing, enterprise web services. The IMS members are due-paying organizations, enterprises, academic institutions and government agencies.

Aviation Industry CBT Committee (AICC)
The AICC is focused on the needs of the aviation industry, which has large investments in both legacy content and legacy training systems. It published one of the first content interoperability specifications. SCORM includes some of the best ideas from the AICC specifications, along with more recent developments in IEEE standards and IMS specifications. The AICC is pursuing the development of updated specifications adapted to the needs of its aviation stakeholders, and strives for wide adoption outside of the aviation industry. The AICC PENS specification (Package Exchange Notification Services) is a protocol to enable "single click publishing" of LMS-ready content between the systems that support elearning.

ISO/IEC

ISO/IEC is the pre-eminent international standards organization. Its members are nations, not organizations or individuals. The scope of ISO standards encompasses all technologies and business processes.

A committee of ISO/IEC, ISO/IEC JTC1 SC36 (http://jtc1sc36.org/), has been working on learning technology standards, and several of the other standards organizations mentioned above have been submitting their specifications and standards to that body for ultimate publication as an ISO standard. Various ISO/IEC standards are referenced in other learning technology standards, which means that implementers of the learning technology standards must be able to look up those standards as well.

The ISO standards documents must typically be purchased. However, some of of the ISO/IEC standards are freely available (http://isotc.iso.org/livelink/livelink/fetch/2000/2489/Ittf_Home/PubliclyAvailableStandards.htm).
