Introduction
  • Charles Duncan
  • Senior lecturer, Edinburgh University, 1980-2002
  • Project manager of many e-learning projects 1985
    present, including EuroMET winner of European
    Academic Software Award 1998

  • Co-founder and CEO, Intrallect, 2000

4
Intrallect provides
  • Solutions for Learning Object Management
  • Strategic consultancy

  • Bespoke development and customisation

5
UK Organisations
  • Schools
  • Primary (5-12)
  • Secondary (12-18)
  • Further Education (FE) Colleges
  • Vocational (16 )
  • In work Training
  • Universities (Higher Education HE)

6
Learning and Teaching bodies
  • JISC1
  • CETIS
  • RDN (Resource Discovery Network)
  • Regional Centres
  • LTSN
  • ILTHE
  • HESDA (Cooke Report2)
  • BeCTA
  • NLN
  • ALT (SURF)
  • Others
  • UKOLN

7
CETIS
  • Centre for Educational Technology
    Interoperability Standards
  • IMS, SCORM, CEN/ISSS, etc
  • News and email discussions
  • SIGS (coordinated)
  • Metadata and digital repositories
  • Pedagogy
  • Accessibility
  • Assessment
  • Educational content

8
Standards
  • Why are standards needed?
  • Sharing
  • Reuse
  • Interoperability
  • Avoid proprietary systems
  • Promotes new activities (or does it?)

9
IMS

Other bodies
  • ADL
  • SCORM
  • IEEE
  • LTSC
  • Learning Object Metadata (LOM)3
  • CEN/ISSS
  • Internationalisation of LOM
  • ISO and national standards bodies

11
Metadata and Beyond
  • IEEE Learning Object Metadata
  • First e-Learning standard
  • Application profiles
  • CanCore, SingCore, UKCMF4
  • Internationalisation
  • CEN/ISSS

12
IEEE LOM
13
Application profiles
  • Mandatory and optional fields
  • Agreed vocabularies
  • Agreed use of indentifiers5
  • Mapping educational levels6
  • Common classification system
  • Minimise/exclude extensions
  • What skills are needed for metadata creation?7

14
Accessibility
15
Learning Object Repositories
  • Networked storage of learning objects8
  • To promote sharing and reuse
  • Learning object economy

16
Digital Repositories are..
  • Not portals
  • Safe, organised, reliable storage
  • Not libraries
  • Not quite, but good analogy
  • Many people can put books on the shelves
  • Not VLEs
  • No prescribed pedagogy
  • Interoperability through standards

17
Digital Repository Interoperability
18
Finding objects
  • Task
  • Search
  • Gather
  • Alert
  • Browse
  • DR Response
  • Expose
  • Object?
  • Metadata?
  • Selected metadata?
  • Priority?

19
Browse
20
Requesting objects
  • Task
  • Request
  • ID?
  • Unique?
  • DR Response
  • Deliver
  • Raw
  • Streamed
  • Packaged
  • Metadata only?

21
Publishing objects
  • Task
  • Publish
  • Metadata?
  • Deliver
  • From one repository
  • DR Response
  • Store
  • Metadata?
  • Store
  • In another repository

22
Aggregator tool
  • Task
  • Aggregate
  • Metadata?
  • DR Response
  • Deliver
  • Update Metadata?
  • Store aggregation

Roles
  • Librarian
  • Contributor
  • Borrower
  • Casual user
  • Administrator
  • Software Agents
  • Alert, search, browse, aggregate, deliver, harvest

28
Some examples
  • SeSDL Scottish electronic Staff Development
    Library
  • http//www.sesdl.scotcit.ac.uk/
  • MERLOT US and Canada
  • http//www.merlot.org/
  • intraLibrary
  • http//www.intrallect.com/

29
Positioning IntraLibrary
  • IntraLibrary is a Learning Object
  • Management System, which means it
  • is a strategic technology which underpins a mixed
    learning environment9
  • improves the management of all learning assets
  • leads to better quality teaching material with
    less effort

30
Current Situation?
31
Using a LOMS

intraLibrary Demonstration

33
Portals
  • One-stop shop?10
  • How many?
  • People change their context
  • Must be adaptable
  • by providers
  • by institutions
  • by individuals

SOSIG Example
36
Bringing it together
  • Key technologies11
  • Z39.50 for searching
  • OAI PMH for exposing metadata
  • RSS for alerting
  • OpenURL for resolving appropriate copy

37
JISC Information Environment
38
The future Learning Design
  • Ability to define learning activities12
  • Capable of handling collaborative learning
  • Design independent of implementation
  • Ability to share and reuse designs

39
MSG-CAL granularity

Interaction/ problem-solving
Name Interaction
MCQ (multiple choice question) Multiple choice question. The question, options and feedback may all include images. There can be many questions in a quiz or only one. More than one correct answer is allowable.
Matrix question Similar to a multiple choice question but there can be several choices such as true/false or visible/ir/wv.
Image hotspot Question in which the answer is given by clicking on an area in an image. Multiple correct and incorrect answers are possible. Multi-spectral images are supported through toggling images from one channel to the next.
Drag and drop Both text-based and image-based drag and drop exercises are possible. These require the student to correctly place objects in defined locations. Multiple correct locations are possible and mismatched numbers of draggable objects and drop locations are also possible. Useful for getting students to label diagrams or construct logical process sequences.
Animation Animate sequences of images with ability to play in single-step, loop or swing modes. Student can control play speed. Includes ability to play only every second image to simulate first generation Meteosat.
Slide show Sequences of images with extended captions with forward and backward paying under student control.
