Setting up IT-mediated project work with secondary school children in a French as a Second Language class gives the opportunity to work on both structural and pragmatic aspects of language. As far as the learning of French is concerned, this classroom technique allows learners to be involved in authentic language activity. The pedagogical project which we set up was organized in two stages: the elaboration of a newspaper followed by the elaboration of a cyber-magazine. The passage between these two stages implies the complete management by the children of the computer tools (the web page layout, computer techniques, and so on). Also, it means confrontation with new learning materials. Our analysis, based on three levels (the learning activities, the collaborative process, the place and function of the computer) aims at pointing out the similarities, novelty or differences between the two stages. Our objective is to decide whether there is rupture or complementarity between the construction and transformation knowledge processes in each stage.
