摘要：We propose to actualization of a framework of reference related to the hypertextuelles
structures within the hyperm¨¦dias (Baron, 1991; Beaufils, 1991; Leclerq, 1991; Wheel, 1992; Nanard,
1995; Bruillard, 1997). This framework of reference, formalized since the beginning of the years 1940
(Mac Culloch & Pitts, 1943), emancipate with project MEMEX initiated by Bush in 1945 (Baron,
1991). The hypertextuelles structuring position the originator and learning it. They give bench marks
on the situations of training and the relevance of the teaching approaches from a technical, practical
and theoretical point of view. The framework of analysis concerning the design of the contents by the
expert, or the professor, is moved towards that of the use which is made by learning by it. This last
specificity does not imply that it is learning it which conceives the course, but which it is less with less
constrained by the preliminary structuring of the course. The data-processing environment of training
can propose a ¡°adaptivity¡± with the user: modification of the interface according to the use of the
system hypertext implemented. It would then be a question of passing from the concept of interactivity
to that of plasticity (Thevenin & Coutaz, 1999).
