Appendix F Telecommunications and training

Television has played an important role in training for many years. The way Open Universities work is the best example of it, on top of educational programmes offered to schools by public and private TV channels. In the first case, learners work alone and are offered to regularly meet with tutors; they receive written material and homework by mail; they are sometimes using computer E-mail to correspond with teachers and other learners. In the second case, the TV educational programme is used in the classroom by the teacher as a support for his or her course.

PC networks (LANs or WANs) offer interactive possibilities, to different extents: access to centralised courseware, to centralised information (dictionaries, encyclopaedias) or virtual classrooms using different types of lines according to the infrastructure existing in the countries, with different one- or two-way audio and/or video transmission.

PC teleconferencing is another interesting tool for training: still frames and audio may be sent in both directions on rather slow lines, or motion video and audio can be sent via faster lines (ISDN, optical fibres). When compressed video is used on both sides of the system, the user can see his or her correspondent and both can see and discuss the same document on their respective screens. Nowadays the market offers different hardware and software packages for this application. PC teleconferencing can be very interesting for remote learners who wish to correspond with other learners, teachers and tutors; questions and answers, opinions, contradictions, etc. can be expressed and solved very quickly using this system.

Different transmission systems can be used:

· ISDN (Integrated Switched Digital Network);
· PSDN (Packet Switched Digital Network);
· PSTN (Public Switched Telephone Network).

Electronic mail (Esnail) has a similar function, but it is more oriented to the one-to-one communication, while in a PC teleconferencing system everyone can read everyone else's input, and anybody can answer or join the discussion.

Last but not least, the Fax (or Fac-simile) is a very simple and cheap means of transferring educational material, homework, questions and answers, etc. at low cost. In some circumstances, it may be the only available tool!
