    • Distributed Learning Environments – an overview Sheila MacNeill, Assistant Director University of Nottingham, VLE review 24/6/2010
    • 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.
    • 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
    • CETIS: website, publications and resources http://jisc.cetis.ac.uk
    • CETIS: website, publications and resources
      • Cloud Computing
      • Business Case for Standards
      • Distributed Learning Environments
      • Semantic Technologies
      • Annual horizon scan
    • Programme support lifecycle
      • Details about this topic
      • Supporting information and examples
      • How it relates to your a Annual Horizon
      • Scanning
      • udience
    • 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
    • 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)
    • Model 1 – Example – Icodeon blog
      • http://ccplatform.blogspot.com/2009/11/organic-chemistry.html
      http://ccplatform.blogspot.com/2009/11/organic-chemistry.html
    • Module 1 – example wookie/moodle http://getwookie.org/moodle/my/index.php
    • 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.
    • Model 2 – Plug-ins to existing VLEs
      • Extending functionality of exiting VLE using plug-ins
    • Model 2 – Example Moodle and cohere http://www.vimeo.com/12700689
    • 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
    • Model 3 – many widgets from the web into one Widget container
      • Mash-up of number of web based sources /resources
    • Model 3 – many widgets from the web into one Widget container - example http://www.netvibes.com/employability#Welcome http://sheensharing.wordpress.com/
    • 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
    • Model 4 – many providers and many clients
      • Google wave
      • Federation of clients and servers creating collaborative spaces
    • Model 4 – many providers and many clients - example http://wave.google.com/about.html
    • Model 4 – many providers and many clients
      • Strengths
      • Highly interactive
      • Highly collaborative
      • Flexible
      • Weaknesses
      • Relatively new technology
      • Usability issues
    • Model 5 – both provider and a client
    • Model 5 – both a provider and a client - example https://camtools.cam.ac.uk/
    • 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
    • Resources, links, contact details
