摘要：The aim of this communication is to emphasize the contributions of the linguistic interactions at the integration of hypermedias documents in a teaching sequence.
While referring to the theory of " the Interlocutory Logic " which allows the study of conversational sequences, we will show that the exchanges between pupils using a hypermedia document, allow on the one hand, to locate the disadvantages of the hypermédia document and on the other hand, to underline the effect of interactions on the cognition of the interlocutors.
In conclusion, the linguistic interactions can constitute at the same time a way to analyse of the hypermedias and a teaching strategy to reduce the difficulties induced by the hypermedia used.
