I'm introducing twiki in the University of Florence as a distance teaching tool. The address is http://didattica.dma.unifi.it but the access is restricted. If someone wants to have a look, please write to me (bagnoli@dmaPLEASENOSPAM.unifi.it). A similar TWiki implementation, freely accessible, is at http://www.complex.unifi.it.
Find attached a document explaining in details what we are doing.
In summary:
The WebTeach suite is composed by three pieces: WebCheck (a database for test scheduling), WebTest (automatic generation/correction of quizzes) and WebWrite, a twiki implementation.
At present TWiki is used to favour interactions among teachers and students.
We would like to use TWiki as THE front-end to all services.
