PIRC• Where we’re going – what an NG system
would look like, what vision it entails• How will we get there – standards (OKI,
Apache, …), CHEF Technology, open source, support for transition

The Next Generation• What we’ve done – the success of CT, WT• What’s the context –increasing adoption,
success, PIRC –President’s Info Revolution Commission
• Where we’re going – what an NG system would look like, what vision it entails
• How will we get there – standards (OKI, Apache, …), CHEF Technology, open source

PIRC – Information Revolution at UM
The University in a Changing Information Environment
Never has the need been more pressing for the University of Michigan to examine its relationship to information and communication technologies. The information revolution that is radically altering our whole world at an ever-accelerating pace touches every aspect of university life.http://www.umich.edu/pres/inforev/
![Page 14: Learning and Research The Next Generation of On-Line Learning Support Systems at the University of Michigan ACSF Presentation May 28, 2002.](https://reader036.fdocuments.us/reader036/viewer/2022081519/56649d545503460f94a30215/html5/thumbnails/14.jpg)
PIRC – Encourage Experimentation
The key is to experiment in a systematic fashion, coordinating and exchanging information across the institution, and in the process transforming the University into a living laboratory.
An “Ecology of Experimentation”
![Page 15: Learning and Research The Next Generation of On-Line Learning Support Systems at the University of Michigan ACSF Presentation May 28, 2002.](https://reader036.fdocuments.us/reader036/viewer/2022081519/56649d545503460f94a30215/html5/thumbnails/15.jpg)
PIRC – Knowledge Networks
Research and scholarship are increasingly interdisciplinary, collaborative efforts. The Internet and new information and communication technologies are enhancing — and transforming — research and scholarship, enabling users scattered throughout the world to share facilities, instruments, immense collections of multimedia information, and tools for analysis and synthesis.
Knowledge Networks
![Page 16: Learning and Research The Next Generation of On-Line Learning Support Systems at the University of Michigan ACSF Presentation May 28, 2002.](https://reader036.fdocuments.us/reader036/viewer/2022081519/56649d545503460f94a30215/html5/thumbnails/16.jpg)
PIRC – Knowledge Networks,Build and study them here
Over the past decade, the University of Michigan has played a key role in designing, developing, and applying knowledge networks. The University should continue to pioneer by further developing knowledge networking technology, exploring innovative uses for it, and studying its impact on the way we work and learn.
Building Knowledge Networks
![Page 17: Learning and Research The Next Generation of On-Line Learning Support Systems at the University of Michigan ACSF Presentation May 28, 2002.](https://reader036.fdocuments.us/reader036/viewer/2022081519/56649d545503460f94a30215/html5/thumbnails/17.jpg)
The Next Generation
• What we’ve done – the success of CT, WT
• What’s the context –increasing adoption, PIRC
• Where we’re going – what an NG system would look like, what vision it entails
• How will we get there – standards (OKI, Apache, …), CHEF Technology, open source
![Page 18: Learning and Research The Next Generation of On-Line Learning Support Systems at the University of Michigan ACSF Presentation May 28, 2002.](https://reader036.fdocuments.us/reader036/viewer/2022081519/56649d545503460f94a30215/html5/thumbnails/18.jpg)
Support for Learning Lifecycle
• Teaching, Learning • Research, collaboration with
colleagues• Making it easy to move from one to
the other Goal:
Integration of research, the practice of knowledge work, within education
![Page 19: Learning and Research The Next Generation of On-Line Learning Support Systems at the University of Michigan ACSF Presentation May 28, 2002.](https://reader036.fdocuments.us/reader036/viewer/2022081519/56649d545503460f94a30215/html5/thumbnails/19.jpg)
Enhancing Distributed Learning –
Continuing to move forward• Building on current functionality – CT,
WT, Lessons• Support for what users need
– Group support– E-portfolio– Case-based tools– Grading, reporting
• Integration– Library resources– printing
![Page 20: Learning and Research The Next Generation of On-Line Learning Support Systems at the University of Michigan ACSF Presentation May 28, 2002.](https://reader036.fdocuments.us/reader036/viewer/2022081519/56649d545503460f94a30215/html5/thumbnails/20.jpg)
Knowledge Networks Vision• Open systems – in all senses
– Open source, build community of support– Open to custom components, cots, fots– Open to all users
• Enabling core competency at University– Teaching/learning, research
• Supporting early adopters• Experimenting at low cost• Encouraging everyone – raising all boats• Leading – we discover we are already – CT/WT
– OKI, JetSpeed, IMS/SCORM (RDF, runtime teamlets)
![Page 21: Learning and Research The Next Generation of On-Line Learning Support Systems at the University of Michigan ACSF Presentation May 28, 2002.](https://reader036.fdocuments.us/reader036/viewer/2022081519/56649d545503460f94a30215/html5/thumbnails/21.jpg)
The Next Generation
• What we’ve done – the success of CT, WT• What’s the context – increasing adoption,
PIRC• Where we’re going – what an NG system
would look like, what vision it entails• How will we get there – standards (OKI,
Apache, …), CHEF Technology, open source, support for transition
![Page 22: Learning and Research The Next Generation of On-Line Learning Support Systems at the University of Michigan ACSF Presentation May 28, 2002.](https://reader036.fdocuments.us/reader036/viewer/2022081519/56649d545503460f94a30215/html5/thumbnails/22.jpg)
Choices in Platform
Why adopt CHEF• open source – code,
tools, developer community
• configurability/customiz-ability - users, admin
• centralization/decentralization of services as appropriate
• aggregation - rss, html, xml - syndication
• prototype rapidly
Why retire Domino• proprietary• rather closed• not as easy adding
features• no community of
developers• finding expertise hard• but, has been good to
us

Integrating Your Own Tools
• Basic Integration– Existing tools– Puts tool immediately into NEES
context with minimal effort• Advanced Integration
– New tools– Develop using Portlet API– Tool can utilize NEES services and
interact with other NEES tools

Integrating Your Own Web Tools: Basic
• Easy way to integrate existing tools• Requires URL Accessible, iFrame
compliant tool (e.g., web page, web app)
• Create simple teamlet definition for tool

Integrating Your Own Tools: Advanced
• Develop tool using Portlet API– Currently using: Jetspeed-1.4 Portlet
API– Summer 2003: JAVA Portlet API 1.0

Data Viewer
• Inputs – repository data• User selects experiment,
channels (data and/or video)
• Choose plot types• Results: tiled, time synchronized
plots of selected channels
Through EA, will accept a limited, early spec data type with minimal user interface

Data Viewer
• EA – prototype available• Will be demo’d at the June 21
NEES Awardees meeting• Post EA
– convert to Chef teamlet– Discussions with Nestor (e.g., Tele-presence
integration)– Add functionality (plots, UI control as
indicated from EA usage)

Support for Transition
• Continuing support for CT, natch• Advance notice of timelines• Input from users - faculty, students,
staff, and other developers - as we go along
• Transition support as we go along,– Media Union staff– Online info, notices of NG development
![Page 67: Learning and Research The Next Generation of On-Line Learning Support Systems at the University of Michigan ACSF Presentation May 28, 2002.](https://reader036.fdocuments.us/reader036/viewer/2022081519/56649d545503460f94a30215/html5/thumbnails/67.jpg)
Transition - CT.NG looks like CT
Design criteria:A user familiar with CT should be able to easily use CT.NG.Interfaces should be recognizable.Actions should be similar.New features should be integrated into familiar frameworks.
