摘要：This short presentation shows (hypothetically) how the organisation of
pedagogical content influences the types of exchange provoked. Information and communication are considered as the two principal (and complementary) vectors in the
context of on-line learning. A characteristic of technology-enhanced training is that it
encompasses both the individual and the collective approach to knowledge, the latter
provoking exchange and interaction between very diversified learner profiles.
The typology of on-line courses and the analysis of exchanges which follow, show that
a sequentially organised course (such as that found in a textbook table of contents) is unlikely
to encourage exchange; on the other hand exchanges are far more frequent in a course
organised at least partly as a network . It is also noteworthy that the two types of organisation
result in different types of exchange.
