  10. INNOVATION Why Bother With Standards? • Standards define and catalyze new technology • Standards enable new solutions • Standards solve existing problems A Tour of Learning Technology Standards

  11. Why Bother With Standards? HELP THE CONSUMER • Standards prevent lock-in • Standards acceleratecommoditization • Standards increase reliability • Standards enable competition A Tour of Learning Technology Standards

  12. Why Bother With Standards? BUILD MARKETS • Standards can lower design, development and production costs • Standards help modularize supply chains • Standards buildconsumerconfidence • Standardization distributes effort A Tour of Learning Technology Standards

  13. Market moves from underservedtooverserved* * Clayton M Christensen & Michael E Raynor, (2003). The Innovator’s Solution: Creating and Sustaining Successful Growth, Harvard Business School Press, Cambridge, Mass. Need arises in an influential community When Does Standardization Occur? INOVATION HELP THE CONSUMER BUILD MARKETS A Tour of Learning Technology Standards

  14. “Education” is an influential community (But not the only one) A Tour of Learning Technology Standards

  15. What is the state of Learning Technology Standards? INOVATION HELP THE CONSUMER BUILD MARKETS MOSTLY HERE SOME HERE STARTING HERE A Tour of Learning Technology Standards

  16. We will now talk about standards organizations and standards A Tour of Learning Technology Standards

  17. But must remember … A Tour of Learning Technology Standards

  18. Nothing is a standard until it is acknowledged and adopted by the community it serves. A Tour of Learning Technology Standards

  19. DLF (1995) History of Relevant Standards Organizations But few new ones since 2001 SISO (1994) EICA OKI IEEE LTSC AICC (1988) CanCore CEN/ISSS WS-LT SIF EdNA (1994) 1996 1997 1998 1999 2000 2001 ARIADNE ADL JTC1 SC36 ebXML IMS Dublin Core (1995) HR-XML CONSOR- TIUM AEN OASIS MERLOT ALIC W3C (1994) A Tour of Learning Technology Standards

  20. Learning technology standardization efforts have been • Driven by • Young companies* • A few key consumer groups • Focused on • Search & Discovery • Learning Content • Learning Delivery Systems (e.g. LMS) • Specialized to Learning • Relatively little adoption of other standards *including new divisions within large software vendors A Tour of Learning Technology Standards

  21. Leading to a diverse portfolio of organizations and standards… A Tour of Learning Technology Standards

  22. The Players • ADL (Advanced Distributed Learning initiative) • AICC (Aviation Industry CBT Committee) • CEN (CEN / ISSS Technical Committee on Learning Technology) • HR-XML (The HR-XML Consortium) • IMS (IMS Global Learning Consortium – a consortium representing Higher Education) • LTSC (IEEE Learning Technology Standards Committee – an accredited standards body) • SC36 (ISO/IEC JTC1 SC36 – Standards for Learning, Education and Training) • WSIL (Web Services in Learning, a vendor effort) A Tour of Learning Technology Standards

  23. Mature Standards with wide Adoption • Metadata • Search & Discovery • SCORM (and AICC equivalents) • Content / LMS interoperability • Made up from IMS & IEEE standards • Question & Test Interoperability • XML representation of Quizzes and test banks A Tour of Learning Technology Standards

  24. IMS Enterprise Interface between an LMS and SIS OKI Service Interface Definitions Used in Higher Education Learning Technology Systems Architecture IEEE standard used by some U.S. Defense contractors Learner Information Package Education & Training Records IMS e-portfolio IMS Learning Design High level instructional design IEEE Digital Rights Expression Languages Recommended practice for education and training IMS Repository Really more of an architecture reference model IMS Sharable State Persistence Integration of LMS / SIM Standards & Specifications with Less Adoption* A Tour of Learning Technology Standards * Based on observation, not hard data

  25. New Consumer-driven Efforts • Frameworks • Not “standards” but frames for conversations about standards • Quality Standards • Address the development of digital learning content • CORDRA • Content Object Repository Discovery Resolution Architecture • Just an architecture and recommended practice • SCORM / SIM Interoperability • Driven by military simulation community A Tour of Learning Technology Standards

  26. New Provider-driven Efforts • Competencies • Defining and modeling learning objectives, skills, knowledge, ability, tasks • Web Services in Learning • Handling LMS / Content Server architecture • Handling “catalog update” • IMS Common Cartridge • Exchange of courses for academic LMS A Tour of Learning Technology Standards

  27. And Some Other Work • Search / Query / Harvesting standards • Several of these, many from other communities • Efforts updating standards by updating view points • Research Aggregation Model (ontology) • Content packaging  UML version / some updates • LOM / Dublin Core Abstract Model A Tour of Learning Technology Standards

  28. Do I need to pay attention to all that? (Probably Not) A Tour of Learning Technology Standards

  29. What does a Consumer need to know? • What problems are being addressed ? • What problems have been solved? • How to ask the right questions • Hint: “Do you conform to X?” is not the right question A Tour of Learning Technology Standards

  30. Problems Being Addressed • Separating content from delivery systems • Making it easier (or possible) to find the right stuff • PREVENTING LOCK-IN • Getting learning systems to talk to other systems A Tour of Learning Technology Standards

  31. Problems Being Solved • Separating content from delivery systems • This is what IMS Content Packaging, SCORM, IMS Question & Test, and AICC standards do. • So far this works well but not perfectly. • Applies only to Web-based content and assessments • Content still needs to be tweaked for specific systems • Making it easier to find the right stuff • This is what metadata does • The biggest problem is the lack of (good) metadata • PREVENTING LOCK-IN (MORE AND MORE) • Getting learning systems to talk to other systems – not really, not yet. A Tour of Learning Technology Standards

  32. How to get an honest and useful answer • Don’t ask about standards, ask about solutions: • After I have developed 100 one-hour courses in your system, what will be the cost to migrate them to a different system? What have you done to make this easy for me? • Don’t ask about conformance – ask for details • What is the minimum set of tags associated with a title in your catalog? Provide a screenshot of your search screen that shows which tags are searchable. Show / explain how authors generate tags in your tools. A Tour of Learning Technology Standards

  33. What does a Content Developer need to know? • How content interoperability standards such as SCORM (and its components) work and what they do • Which standards are used by authoring tools and supported by delivery systems A Tour of Learning Technology Standards

  34. What does a Technology Developer need to know? • Where standards are along the adoption and implementation curve • Details and best practices for standards relevant to the technology being developed and that are • Being used in the market - or- • Provide solutions to specific problems (e.g. integrating with a SIS) - or- • Confer a competitive advantage A Tour of Learning Technology Standards

  35. Example 1 Publishing content as a business … • Accepted standards: • Metadata, DOI, SCORM / AICC, OAI-PMH, SRU/SRW, SQI • Emerging standards: • CORDRA • Possible relevant standards: • Query standards, Digital Rights Expression Language, Quality standards • Standards that address the functionality of content, e.g. Sharable State Persistence if the content interacts with simulations or games or Learning Design • Specifications to watch • IMS Common Cartridge (academic), Web Services in Learning A Tour of Learning Technology Standards

  36. Example 2 Building a serious simulation / game … • Accepted standards: • Metadata, High Level Architecture, OpenGL (and Simple DirectMedia Layer) • Emerging standards: • Not sure • Possible relevant learning technology standards: • SCORM, Sharable State Persistence, e-portfolio • Specifications to watch • SIM/SCORM Study Group A Tour of Learning Technology Standards
