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 of its workforce as opposed to its geography, trade laws, patents, and natural resources.”
“The worker of the 21st century must have science, math, and information technologies skills, 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

Today’s Education Challenges
Information & knowledge is growing exponentially
Teaching methods and materials do not keep pace
Learning today is too passive and static: learning by listening and watching
But, Life is highly active, dynamic, multi-tasking
Students become de-motivated and lack creativity
Existing e-Learning environments are scratching the surface
I’ve tried to tell Bill he’s overloadinghimself with
too much information
We need 1000s of new jobs in science and engineering
We have to start with K-12 students and their teachers !

=> 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

e-University: Fluid-Structure Interaction
This model exemplifies how fluid-structure interactions can be modeled using COMSOL Multiphysics. Viscous forces and the system’s pressure impose forces to the surface of a structure. The deformation in the soft structure is not small and the fluid regime will therefore dynamically change: change in the structure is coupled back to the fluid dynamics.COMSOL solves this phenomena using the Arbitrary Langrangian-Eulerian (ALE) method. This ensures a true coupling of the physics and the mesh deformation, solved simulataneously.

e-University: Dynamics of the Bladder
This model simulates a common dynamic test bladder functionality. The purpose of the model is to estimate the displacement and stresses on the bladder walls during this
test. The test consists of subjecting a fluid-filled bladder to a dynamic pulse, more specifically, two short
coughs. The pressure in the urethra is monitored during the test. The aim of the test is to draw conclusions about the cause of incontinence and to determine treatment. One of the main difficulties of the model is the generation of the geometry from the CAT (Computed
Axial Tomography) scan images; here COMSOL Multiphysics interface with COMSOL Script becomes very handy.

e-University: Magnetic Drug Targeting in Cancer Therapy
Current research on methods to target chemotherapy drugs in the human body includes the investigation of bio compatible magnetic nano-carrier systems, e.g., magnetic liquids such as ferro-fluids.This model example investigates an external magnetic field and its interaction with blood flow containing a magnetic carrier substance. The model is based on the Maxwell and Navier-Stokes equations, where a static magnetic field is coupled to fluid flow. This is achieved by adding a magnetic volume force to the Navier Stokes equations, which stems from the solution of magnetic field problem. Model provided by Daniel Strauss, the Institute for new Materials, Germany.

e-University: Sloshing Tank
Transport of large quantities of fluid can happen in unstable environments. A perfect example is an oil tanker on the high seas. This model uses ALE for an incompressible Navier-Stokes problem with a free surface. This models the fluid with its original mesh, but allows the mesh to deform according to the fluid’s
‘deformation’. This requires that the position of the mesh and its nodes be directly coupled to the position of the fluid. The fluid is sloshing in a 2D container. The fluid movement is driven by the fact that the gravitational vector direction is varying periodically.
