  • 1. Distributed Learning Environments – an overview Sheila MacNeill, Assistant Director University of Nottingham, VLE review 24/6/2010
  • 2. JISC CETIS
    • JISC Innovation Support Centre (ISC).
    • Provide strategic advice to the JISC, support its development programmes.
    • Represent UK HE sector on international standardisation initiatives.
    • Work with the wider educational community to facilitate the use of standards based e-Learning.
    • Support the current JISC eLearning programme.
  • 3. Community Engagement
    • Beginning with SIGs
    • Accessibility
    • Assessment
    • Educational Content (EC)
    • E-portfolio
    • Enterprise
    • Metadata and Digital Repositories (MDR)
    • Lifelong learning group
    • Pedagogy Forum
    • Now – working groups
    • Short life-span, specific outputs, smaller scale than SIGs
    • More agile response to needs of community
    • E.g.
      • QTI profiling
      • Semantic technologies in teaching and learning
      • Widgets
  • 4. CETIS: website, publications and resources http://jisc.cetis.ac.uk
  • 5. CETIS: website, publications and resources
    • Cloud Computing
    • Business Case for Standards
    • Distributed Learning Environments
    • Semantic Technologies
    • Annual horizon scan
  • 6. Programme support lifecycle
  • 7.
    • Details about this topic
    • Supporting information and examples
    • How it relates to your a Annual Horizon
    • Scanning
    • udience
  • 8. Distributed (Virtual) Learning Environments – what are they?
    • Building on existing technologies
    • Natural progression of mash-ups/widget developments
    • New ways to use/build/extend/integrate learning environments
    • Lightweight, user centred, utilising web services, standards and the cloud
  • 9. Model 1: One system in the cloud, many outlets
    • Services gathered in one place (the cloud), - broadcast out to variety of delivery platforms (VLE, blog, mobile device)
  • 10. Model 1 – Example – Icodeon blog
    • http://ccplatform.blogspot.com/2009/11/organic-chemistry.html
    http://ccplatform.blogspot.com/2009/11/organic-chemistry.html
  • 11. Module 1 – example wookie/moodle http://getwookie.org/moodle/my/index.php
  • 12. Model 1: One system in the cloud, many outlets
    • Strengths
    • Secure integration with current systems
    • Growing developer community
    • Easy deployment on multiple platforms
    • Weaknesses
    • No standard way to feed user interaction back to other applications
    • Some competing standards
    • Implementation in early stages.
  • 13. Model 2 – Plug-ins to existing VLEs
    • Extending functionality of exiting VLE using plug-ins
  • 14. Model 2 – Example Moodle and cohere http://www.vimeo.com/12700689
  • 15. Model 2 : Plug-ins to existing VLEs
    • Strengths
    • Data interaction between plugin and VLE
    • Growing developer community within HE sector
    • Potential to share many tools/plug-ins across the sector
    • Weaknesses
    • Dependency on host VLEs
    • Full IMS LTI spec underdevelopment
    • Not so great for integrating social media tools from web
  • 16. Model 3 – many widgets from the web into one Widget container
    • Mash-up of number of web based sources /resources
  • 17. Model 3 – many widgets from the web into one Widget container - example http://www.netvibes.com/employability#Welcome http://sheensharing.wordpress.com/
  • 18. Model 3 – many widgets from the web into one Widget container
    • Strengths
    • Easy to set up
    • Low cost – mainly freely available tools/services
    • Demonstrates aggregation of resources into a collective space
    • Weaknesses
    • Need some technical confidence
    • Lack of durability – might not always be free
    • Lack of integration with institutional systems
    • Limited scope for integration of any service requiring authentication
  • 19. Model 4 – many providers and many clients
    • Google wave
    • Federation of clients and servers creating collaborative spaces
  • 20. Model 4 – many providers and many clients - example http://wave.google.com/about.html
  • 21. Model 4 – many providers and many clients
    • Strengths
    • Highly interactive
    • Highly collaborative
    • Flexible
    • Weaknesses
    • Relatively new technology
    • Usability issues
  • 22. Model 5 – both provider and a client
  • 23. Model 5 – both a provider and a client - example https://camtools.cam.ac.uk/
  • 24. Model 5 – both a provider and a client
    • Strengths
    • Flexibility
    • Lets every system play to its strengths
    • Truly distributed architecture
    • Many options for sharing functionality
    • Weaknesses
    • Not many (UK) implementations
    • Heavy load on provider and client
    • Potential single point of failure
  • 25. Resources, links, contact details
