Outline
  1. Standards in general
  2. Learning technology standards
  3. Some technical details
  4. Whats next
  5. Open discussion

3
No results found
4
Standards Can
  1. Specify the form and function of technology
  2. Determine how information is exchanged
  3. Require procedures to be followed
  4. Define acceptable outcomes

5
Standards Can
  • Specify the form and function of technology
  • Determine how information is exchanged
  • Require procedures to be followed
  • Define acceptable outcomes

Learning technology standards define
technological infrastructure

We converse today about the details so that we
may not converse about them tomorrow and the day
after.
10
Why Bother With Standards?
  • Standards define and catalyze new technology
  • Standards enable new solutions
  • Standards solve existing problems

11
Why Bother With Standards?

HELP THE CONSUMER
  • Standards prevent lock-in
  • Standards accelerate commoditization
  • Standards increase reliability
  • Standards enable competition

12
Why Bother With Standards?


BUILD MARKETS
  • Standards can lower design, development and
    production costs
  • Standards help modularize supply chains
  • Standards build consumer confidence
  • Standardization distributes effort

13
When Does Standardization Occur?
INOVATION
HELP THE CONSUMER
BUILD MARKETS
14
Education is an influential community
(But not the only one)
15
What is the state of Learning Technology
Standards?
INOVATION
HELP THE CONSUMER
BUILD MARKETS
MOSTLY HERE
SOME HERE
STARTING HERE
16
We will now talk about standards organizations
and standards
17
But must remember
18
Nothing is a standard until it is acknowledged
and adopted by the community it serves.

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
21
Leading to a diverse portfolio of organizations
and 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)

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

24
Standards Specifications with Less Adoption
  • 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

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

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

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

28
Do I need to pay attention to all that?
(Probably Not)
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

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

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.

32
How to get an honest and useful answer
  • Dont 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?
  • Dont 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.

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

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

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

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

37
Details on SCORM
  • WHAT IT DOES
  • HOW IT WORKS

39
WHAT IS SCORM?
  • A REFERENCE MODEL A set of profiles of standards
    and specifications that tells you how to do
    something useful
  • A SOLUTION Solves the problem of separating
    Web-based training content from delivery systems
  • A STANDARD
  • Adopted by most commercial LMS products
  • Required by government directives (U.S., Korea )
  • SCORM 2004, 3rd Edition, is on track to being
    standardized as an ISO technical report
  • SCORM means SCORM 2004 in this presentation

Sequencing Navigation
  • Activities are aggregated and organized into a
    tree.
  • A default traversal path can be modified by a
    learning designer.
  • Traversal is triggered by a sequencing request.
  • Request is triggered either by the learner
    through navigation events or by the delivery
    system.
  • Sequencing rules are evaluated at runtime and can
    be conditional.
  • Activities are delivered one at a time.
  • Actual content resides in leaves of the tree

50
Remediation Using Objectives
Rule Exit if Obj_1 AND Obj_2 are Satisfied.
Else, Continue.
Rule Skip Lesson 1 if Obj_1 is Satisfied

61
WEB 2.0 ITS NOT YOUR TEACHERS WEB ANY MORE
BUT, LIKE ALL STANDARDS, SCORM IS OLD SCHOOL
62
SO WHATS NEXT?
63
TRENDS ISSUES
  • Underlying Topology
  • Client / Server replaced by a distributed model
    with multiple content servers
  • Underlying Philosophy
  • Provider broadcast replaced by user collage
  • Mass production replaced by mass customization
  • Learning Technology
  • Learning Management Systems replaced by
    personalized learning environments
  • Passive learning replaced by interactive control

64
In general
  • Learning is becoming more embedded
  • Learning technology is becoming less
    distinguishable from other technology
  • Learning technology standards are borrowing more
    from other domains
  • The problem is no longer managing learning The
    problem is letting learning take place and
    managing everything around it.

65
Buzzwords Watch List
  • Personal learning environments (CETIS project)
  • Web services
  • Web Services based on a specific set of
    standards that solve enterprise scalability
  • Web services based on a different collection of
    standards that solve Web 2.0 scalability
  • Competencies the neglected building block of
    learning
  • Repository standards, because we still need to
    get to seek, and ye shall find.
