You have nothing to lose but your chains …
REC

Mature technologies: XML, Flash, web applications etc
Mature specifications: learning objects, metadata, sequencing, learning design
Mature contexts: LMS/VLEs, portals, repositories,
Mature uses: pedagogy, andragogy, heutagogy, blended learning
How high an LTech ‘body count’ will we tolerate?
Now IS the time
REC
AL
3-year project based at the University of Edinburgh
Concentrating on biomedical sciences
Developing a decoupled CAL object model
Separate assets, instructions, templates and runtime shells
Developing a user community
Shared and open research & development
RECAL: an answer
REC
AL
RECAL Architecture
• Assets: images, sounds, movies, animations, data, html, css
• Elements: generic page and other rendering templates - 1˚ in MM Flash
• Sequencing: pages & their metadata, rendering preferences, sequence and presentation - XML
• Runtime: generic shell(s) - 1˚ in MM Flash

If RECAL then:
Templates, branding and skins - accessibility
Different run-time
Changing epistemology
Changing pedagogy
Changing sequencing
Changing resources and content
Adaptation: language, culture etc
Why was that again?
REC
AL
Objects are fine, but what about future-proofing and interoperability?
RECAL will use e-learning standards and specifications:
• Learning objects: IEEE LOM
• Sequencing: SCORM, IMSSS, IMSLD
• Distribution: IMSCP, IMSDR
• ?state, ?learner
Standards and Specifications
REC
AL
RECAL is not about doing things ‘to’ people but ‘with’ people
Nurturing a developer community:
• testing and evaluation
• adaptation and translation
• new templates and materials
• new learning designs
RECAL Development Community
REC

Tension between abstraction and functionality
Specifications still evolving
Ownership and control
Legacy mountain
Developing skills
Developing infrastructure
Changing the culture
Issues
REC

Proof-of-concept and technology R&D
Standards and specifications
Disaggregation and reaggregation
Repository
Developer tools
Developer community
And then ……
