1: Nevertheless do you have the impression that you are doing a practical course in electronics?
2: Is the fact that the instruments are abroad motivating or without interest for you?
3: Would you wish that other practical courses are put on line?

Reliability aspectsReliability aspects
• During 20 sessions the Retwine tool was in use
• It failed 4 times
► (3 times with the same professor !!!)
► WWW = World Wide Wait, be patient
► 1 time: Intranet network problems

ConclusionConclusionThe realisation is possibleSome teachers have more problems than students in
using the new toolInternet connection problems occur sometimes,
be patientThe students seem to appreciate the new approachThey are satisfied and enthusiasticThe students could attend to “most modern practical
courses” with high tech instruments

T. Zimmer Minerva Coordinators Meeting – June 2001 Brussels (Belgium)
PerspectivesPerspectives
• Horizontal– RETWINE: adding new instruments and the corresponding tutorials to
the instrumentation pool
• Vertical– Use the RETWINE opportunity to perform practical courses in a virtual
Lab
– Integrated course concept in scientific fields for e-Learning
A new Minerva project ?
