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

- development of the interactive

teaching platform

13 Universities (16 groups)

- creating contents (learning units)

- all chemistry disciplines involved

  • undergraduate students in chemistry

  • graduate students

  • -further education

VIPRATECH

Idea: online laboratory course in chemical engineering and unit operations

Aim: support and improvement- carrying out a real experiment

- evaluation of data

- experiment manual

web-based material (Experiment LUs)

remote control experiments

manuals

Observe and control an experiment by using a standard web-browser

  • hardware description

  • experimental objectivs

  • theoretical backgrounds

  • offline experiments

  • online experiment

  • evaluation of data

  • interactive simulation

  • self control

  • Sharing expensive lab resources

  • Bringing lab experiments into the lecture hall

  • Enabling more flexible timetabling of labs

  • Sharing resources

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

Recording a real Experiment

(Data, Video, Audio)

Database

SMIL Animation

Streaming Server

Internet/ Intranet

Web-Browser

Experiment LU – Offline Experiment

  • access to distant laboratory equipment (experiment) by VSC Experiment LU

  • Using a streaming client

Online – Experiment : Remote Control

Why?: - Sharing expensive lab resources

- Bringing lab experiments into the lecture hall

- Enabling more flexible timetabling of labs …

Experiment

Data Aquisition :

TCP/IP-based hardware

Observation:

WEB-CAM

Remote Control Server

(MIFFY)

Camera Server

Internet/ Intranet

Web-Browser

Experiment LU – Online Experiment

  • access to distant laboratory equipment (experiment) by VSC Experiment LU

  • 3 web pages: user management ; scheduling ; remote access

  • Java-Client: Java Bean Library to create Java Clients

    - realized: simple scheduling, user management

Adsorption

  • In 2004 the adsorption experiment has

  • been realized

  • aim: building ,testing and analyzing

  • a network of remote controled experiments

Vipratech experiences

VIPRATECH: Experiences

  • being in use for the last 4 years

  • high reliability of servers (MIFFY)

  • easy to create servers/clientsServer: 1 day; Client: 4-6 weeks

  • Who is using it?Students from Leipzig / Oldenburg/..

  • most used experiment in 2004 :RTD Experiment (2004: 96h, 271 sessions)

ICEE 2005 Gliwice/PL (c) R.Moros, ITC Leipzig


Vipratech experiences1

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:building a network of remotely controlled experiments
