Standard

Definition

• The goal of standardization is to improve efficiency of actions and interactions.

There are various degrees of technical standards:

1. "Real standards" of very high formal quality adopted by bodies such as ISO, IEE, IEC, ITU, etc.
2. Standards like the W3C "Recommendations" or the IETF "Requests for Comments" (RFCs) or the OASIS document standards.
3. De facto standards (usually no formalization at all) like Microsoft products.

• Standards can be open or propriety. Open means publicly available, not necessarily free.

Standards in educational technology

See also educational modeling language that deals in more depth with the question of modeling learning materials and activities

Pedagogical standards

There are no real general standards, but the closet things are

• Rather formal Instructional design methods like MISA who do make a few minimal assuptions about good pedagogy
• Data standards like IMS Learning Design or IMS Simple Sequencing do rely or support some classes of instructional design models. Even IMS Content Packaging default organisation section can be considered a pedagogical standard if one considers that "shovelware" or "page turners" are a standard pedagogical design ;)

• In some countries there are quite precise curricula standards, e.g.
  • American Association for the Advancement of Science’s (AAAS, 1993) Benchmarks for Science Literacy
  • National Research Council’s (NRC, 1996) National Science Education Standards,

Pedagogical data standards

• IMS Content Packaging, a standard for assembly of resources, metadata and sequencing information into a learning object
• IEEE Learning Object Metadata Standard (LOM), a standard to describe artifacts
• IMS Learning Design and IMS Simple Sequencing, to describe pedagogical scenarios
• IMS Question and Test Interoperability (QTI), a test and testing data standard
• There are more IMS Global Learning Consortium standards, e.g. some related to student data.
• The SCORM 1.2 profile extends IMS Content Packaging with more sophisticated sequencing and Contents-to-LMS communication
• The SCORM 2004 profile includes IMS Simple Sequencing

Systems standards

• The SCORM specifications define some java-script bindings to insure interroperability of simple interactive contents (that is BTW one of the areas where a lot of systems are not Scorm compatible, even if they claim so ...)
• IMS General Web Services to allow for interoperability of various systems. This is a fairly new standard (Jan 2006) and is an interesting initiative.

Content Packaging (overall structure of a reusable learning object and minimal sequencing)
[[IMS Content Packaging]]	1.1.2 (8/2001)	The IMS Content Packaging Specification provides the functionality to describe and package learning materials, such as an individual course or a collection of courses, into interoperable, distributable packages.

Standardization bodies

This is a list of bodies that create "real" or "de facto" standards

• W3C - World Wide Web Consortium (Web standards)

• OASIS

• The Internet Engineering Task Force (part of the Internet Society

• RFC - Requests for comments (Informal Internet standards, sometimes standardized by an "official body" sometimes not. The most important source for Internet standards.)

General

(including ICT standards)

• ISO - International Organization of Standardization (many very formal ICT standards).

• CEN - European Committe for Standardization ,featuring a not standards-compliant webpage ;)

• CETIS - the centre for educational technology interoperability standards A British consortium that is the best overall resource on standards related to our field.

• Resource-Base - Standards, Architectures and Open Source in Education. Large index (backended with delious so get nice tag clouds).
