History (since 2002)

• Bi-annual Engineering Week of INPG
• Less students choose science
• Public highschool students (15 years old)
• Goal discover research and engineering
• How 1 week of tutorials
• MobiNet Tutorials
• GRAVIR / IMAG-INRIA

3
Mobinet Interactive simulation software

• Put theory into practice
• develop intuition
• introduce scientific, engineering approach
• Try, understand and learn
• accessible, easy to use
• no fear of making mistakes
• Develop team work
• networked simulation space

4
MobiNet approach

• Experience notions, visually !

5
MobiNet approach

• Model of real world
• Objects state variables (x)
• ? mathematical model
• Objects motion (x x1)
• ? physical model of behavior
• Nothing magic !
