Motivation: Educational Value Proposition
• Access to Quality Content• Transformations in Form
– Traditional Virtual
• Transformations in Function– Knowing Affecting and Changing
• A pedagogy of abundance– Connected; Continuous; Community
• Impediments and Sustainability

Worldwide Collaboration through Online Laboratories
“If you can’t come to the lab… the lab will come to you!”
iLab: worldwide collaborationNUS (Singapore, 13 time zones)
Since Fall 2000(20-30 students/yr)
iLabs at MIT
Shake table (Civil Eng., to be deployed early 2004)
Flagpole (Civil Eng., deployed 2000, inactive)
Polymer crystallization (Chem. E., deployed 2003)
Microelectronics device characterization (EECS, deployed 1998) Heat exchanger (Chem. E., deployed 2001)STEF
Value of iLabs
• Pedagogy (Opportunity & Flexibility).
– iLabs create laboratory experiences in subjects that didn’t have them before.
– iLabs enable laboratory experiments at most opportune moment in curriculum.
– iLabs allow students to perform experiments in pleasant environments at times of their choice
– iLabs allow students to work in a “stop-and-go” mode
iLab: impact on MIT studentsMIT graduate and undergraduate coursessince Fall 1998
iLabs Value• Labs can be located in places inaccessible to students
• iLabs hold unique scaling characteristics: - round the clock usage; from anywhere in the world
- iLabs can be broadly shared: fundamental change in economics of the lab experience
– Order-of-magnitude more laboratory experiences available to students
– Can afford sophisticated labs involving:
advanced instrumentation; rare materials; unreachable locations
• iLabs embedded inside rich educational platforms containing visualization tools, simulations, data processing remote collaboration and tutoring
• iLabs will spawn communities of learners to share hardware and educational content

One-to-One Vision• Transform Athena into a:
– Collection of services to support student-owned computing and selected cross-department shared computing resources
• special-purpose computing facilities, shared file spaces, collaboration tools, and Application management
One-to-One Computing Status• Laptop Educational Projects (4)
• Laptop loaner program• Experiments in tablet PCs, and
handhelds• Leveraging commodity
computing and individual ownership– Providing services and software
for machines not owned by MIT– Managing licenses and
distribution of DLC owned software
– Managed Windows,– Open AFS client for Linux
IS Customer Survey Spring 2003
Continuation of trend toward student laptop ownership
• Limited penetration of laptops in curriculum
• Standard suite of software needed – Especially for Windows
• Transition of traditional public Athena clusters
• Wireless coverage of residence halls – Lack of Institute service provision

Educational Value Proposition
• Proximities– First Hand; Learner-Teacher; Research-
Teaching
• Choice– time, location, modality
• Active Learning– Experience; Project based; Collaborative
Educational Value Proposition
• Quality Content• Transformations in Form
– Traditional Virtual
• Transformations in Function– Knowing Affecting and Changing
• A pedagogy of abundance– Connected; Continuous; Community
• Sustainable ecology
Pervasive Impediments• Network bandwidth is not uniform throughout.
• No cohesive computing, life, and learning strategy
• Technical and Business models for delivering software and services to a heterogeneous (dis)connected environment not yet there.
• No deliberate curriculum strategy to leverage pervasive computing.
• Logistical impediments: weight, form factor, security

Endgame 1“What is the problem to which headlamp washer-wipers are the
solution?”Neil Postman. Educom Conference 1992
• Enable the movement and manipulation of educational materials - Simply, Meaningfully– Portability– Interoperability– Reusability
• An ecology characterized by Open, Community or proprietary Source Commodities that provide :– Value (heterogeneous)– Choice (of Technology and Tools)– Sustainability
