The future: learning design?
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
– CETIS EC SIG co-chair 2000-2002– Co-founder and CEO, Intrallect, 2000 –
Intrallect provides
• Solutions for Learning Object Management– Strategic consultancy– Software– Bespoke development and
customisation
UK Organisations
• Schools – Primary (5-12)– Secondary (12-18)
• Further Education (FE) Colleges– Vocational (16 + )– “In work” Training
• Universities (Higher Education HE)
Learning and Teaching bodies
• JISC1
– CETIS– RDN (Resource Discovery Network)– Regional Centres
• LTSN• ILTHE• HESDA (Cooke Report2)• BeCTA
– NLN• ALT (SURF)• Others
– UKOLN– UK-MEG
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
Standards
• Why are standards needed?– Sharing – Reuse– Interoperability– Avoid proprietary systems– Promotes new activities (or does it?)

Other bodies
• ADL– SCORM
• IEEE – LTSC
• Learning Object Metadata (LOM)3
• CEN/ISSS– Internationalisation of LOM
• ISO and national standards bodies
Metadata and Beyond
• IEEE Learning Object Metadata– First e-Learning standard
• Application profiles– CanCore, SingCore, UKCMF4
• Internationalisation– CEN/ISSS
IEEE LOM
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

Learning Object Repositories
• Networked storage of learning objects8
– To promote sharing and reuse– Learning object economy
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
Digital Repository Interoperability
Finding objects
Task
• Search • Gather• Alert • Browse
DR Response
• Expose– Object?– Metadata?– Selected
metadata?– Priority?
Browse
Requesting objects
Task
• Request– ID?– Unique?
DR Response
• Deliver– Raw– Streamed– Packaged– Metadata only?
Publishing objects
Task
• Publish– Metadata?
• Deliver– From one
repository
DR Response
• Store– Metadata?
• Store– In another
repository
Aggregator tool
Task
• Aggregate– Metadata?
DR Response
• Deliver– Update Metadata?
• Store aggregation
preparing presentations

Roles
• Librarian• Contributor• Borrower• Casual user• Administrator• Software Agents
– Alert, search, browse, aggregate, deliver, harvest
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/
Positioning IntraLibrary
IntraLibrary is a Learning ObjectManagement 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
Current Situation?
Using a LOMS
intraLibrary Demonstration

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

SOSIG Example
Bringing it together
• Key technologies11
– Z39.50 for searching– OAI PMH for exposing metadata– RSS for alerting– OpenURL for resolving “appropriate
copy”
JISC Information Environment
The future: Learning Design
• Ability to define learning activities12
• Capable of handling collaborative learning
• Design independent of implementation
• Ability to share and reuse designs
MSG-CAL granularity
course Structure, size and duration of a course are totally determined by teachers
modulemodulemodule Largest part of MSG-CAL, about 45 minutes long,
complex navigation includes sequences and choices
modulemoduleunit-of-study Between 5 and 10 per module, includes specific
reference library, external URL and communications groups. Knowledge objects arranged linearly
modulemoduleknowledge-object Between 2 and 4 per unit of study. Equivalent to
a web page. Usually contains one interaction
modulemoduleresource Fundamental resources such as images,
animations and video.
Interaction/ problem-solvingName 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.
