Why Math-Bridge?Why Math-Bridge?
• Numbers of graduated engineers insufficient– Germany 1996: 52.278– 2002: 31.000

Why Math-Bridge?Why Math-Bridge?
• Students lack mathematics competencies for (engineering) fields-of-study all over Europe
• Drop-out rates high in Europe! 15-60%• No. of graduated engineers insufficient
– E.g., Germany 1996: 52.278– 2002: 31.000
A possible remedy:personalized online Bridge Courses

Why Math-Bridge? Why Math-Bridge?
• Existing remedial courses for higher education insufficient:– Do not adapt enough to individual students– Do not adapt enough to field-of-study– Do not illustrate early enough importance of
mathematics in field-of-study

Ava Babili
• Existing digital content not properly reusable– single languages instead of multi-lingual– not interoperable– not standard compliant (or no metadata)– not for all colleges and universities
• Existing digital content not well accessible– No semantic search– No cultural-adaptiv search
• Existing digital content with little interactivity• Existing digital content without cultural
adaptation

Main Goals of the Main Goals of the Project Project
– Bridge the Mathematics gap between schools and higher education in Europe
– Enhance several large European content sources to
interoperable format, use them in Math-Bridge service
– Improved use and reuse through ActiveMath– Multi-lingual and multi-cultural access
• English, German, Finnish, French, Dutch, Hungaria, Spanish
– Customize ActiveMath platform for personalized remedial service
