VS-C – Network for Chemistry Education
Federal Strategic Project in Germany 1999 – 2004
Aims
- network of knowledge modules (Learning Unit ) for undergraduate studies in
chemistry
- LU: 45..60 min ; can be combined to a teaching path
- using a web-based interactive teaching platform
Partners
Usergroups
FIZ Chemie GmbH
- project management

Offline – Experiment
- based on real measured data
- more then one user can carry out an Offline Experiment
- saving real measured data
- close to the real experiment

being in use for the last 4 years
high reliability of servers (MIFFY)
easy to create servers/clients
Who is using it?
Server: 1 day; Client: 4-6 weeks
Students from Leipzig / Oldenburg/..

VIPRATECH: Experiences
Problems:
no problems with client/server
- User management/Scheduling if 2 (or more) Lab providers
- Data storage; Data delivery (e-mails, ftp, download,..)
Necessary to outsource service functions
Next Steps:
Lab Provider and Service Provider
Service Provider which provides all service functions
(user management, scheduling, data storage, data
delivery, statistics, billing,..)
more experiments
(laboratory courses, automation of lab units,..)
translation LUs in other languages
Dream:
07/2005
building a network of remotely controlled experiments
