• The Challenge: world-wide data and knowledge explosion
• The Challenge: we need more scientists and engineers, but
students are not interested
• The Challenge: schools and teachers are not prepared
• The Solution: new ways of teaching and learning for our digital natives
• The Technology: e-Infrastructures for enriched learning
• The Didactics: working with didactic and pedagogic experts
• The Prototype: e-School, interactive science laboratory, the
digital sand-box for life-long learning

Data Challenges Today
“The amount of scientific data is doubling every year, and mining, analysis, knowledge and reproduction is becoming very complex.”
A.Szalay & J.Gray: Science in an exponential world.
In: Nature, Vol 440, 23 March 2006.
This trend is likely to continue:
- Moore, Gilder, Metcalf Laws continue- In 3-5 years: 10-fold more processing,
. storage, and also network bandwidth- This will result in 10 times more data- Science is scaling up (e.g. LHC) and
. scaling out (commodity technologies)Copy: Aple iPod Ad fromSueddeutsche Magazine June 2 2006

But
Education

!!!
Our knowledge doubles every 12 months !

New cultural community that supports peer collaboration and new modes of education, based upon
- broad and open access to leadership computing;
- data and information resources;
- online instruments and observatories; and
- visualization and collaboration services.
CI enables distributed knowledge communities that collaborate and communicate across disciplines, distances and cultures.
Research and education communities beyond traditional brick-and-mortar facilities, becoming virtual organizations that transcend geographic and institutional boundaries.
Dr. Arden L. Bement, Jr.
Director of the National Science Foundation, in March 2007

Emerging IT is reshaping education
� Economic & technological shifts change education dramatically
� IT is becoming the foundation of knowledge and skills
� Changes in the characteristics and behaviors of learners
� “Competitive advantage for a region is now built on the skills ofits workforce as opposed to its geography, trade laws, patents, and natural resources.”
“The workers of the 21st century must have skills in science, math, and information technologies, creativity, and the ability to solve complex problems.” C.Dede, S.Corte, R.Nelson, G.Valdes, D.Ward, 2005
Transforming Learning for the 21st Century: An Economic Imperative
� “States must foster, support, and enhance online learning for all students and develop 21st century citizens with the capacity for lifelong learning and productivity! John Watson et all, 2005
Keeping Pace with K-12 Online Learning
BELIEF-6Choice Delhi Jan 29 2009 Wolfgang Gentzsche-School
Today’s Education Challenges
� Information & knowledge is growing exponentially
� Teaching methods and materials do not keep pace
� Learning today is too passive and static, life is highly active and dynamic
� Students become de-motivated and lack creativity
� e-Learning environments are scratching the surface
We need 100Ks of We have to focus
new jobs in science on K-12 students and engineering and their teachers
I’ve tried to tell Bill he’s overloadinghimself with too much information

Vision:Establish persistent European HPC ecosystem integrating national Tier-1 (Tflop/s) and Tier-0 (Pflop/s) centres.
Mission:Enhance Europe’s capability in computing and science by integratingsupercomputers into European HPC e-infrastructure.
Build European Supercomputing Service on top of existing national services, based on the deployment and operation of a persistent,production quality, distributed supercomputing environment with continental scope.
Strategy:
Consolidate the existing DEISA1 HPC infrastructure and services.
Deliver a turnkey operational solution for the future persistent European HPC ecosystem.

Distance Learning on e-Infrastructures
Distance Learning...
• Independent of time and space
• Self-paced learning
• Teacher-independent learning
• Deductive science education
• Mostly single-learner envirnmt.
• Linear inter-reactivity, at best
• Mostly static and repetitive
=> Improved (but similar to)
class-room learning
...on e-Infrastructures
• Independent of time and space
• Self-paced learning
• Teacher-independent learning
• Inquiry-based science education
• Allows for collaborating groups
• Fully nonlinear interactivity
• Highly dynamic and nonlinear
• Allows for complex simulations, data processing, and visualization
• Brings creativity, motivation and commitment to the students and to the teachers
=> Paradigm Shift
