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

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)
Model 1 – Example – Icodeon blog

Module 1 – example wookie/moodle

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
Model 2 – Example Moodle and cohere

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
15
Model 3 – many widgets from the web into one Widget container
Mash-up of number of web based sources /resources
16
Model 3 – many widgets from the web into one Widget container - example
17
http://www.netvibes.com/employability#Welcomehttp://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
18
Model 4 – many providers and many clients
Google wave Federation of
clients and servers creating collaborative spaces
19
Model 4 – many providers and many clients - example
20http://wave.google.com/about.html
Model 4 – many providers and many clients
Strengths Highly interactive Highly collaborative Flexible
Weaknesses Relatively new
technology Usability issues
21
Model 5 – both provider and a client
22
Model 5 – both a provider and a client - example
23
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
