%0 Journal Article %T Interactive Trace Visualization for Reflexivity: Application to the synchronous collaborative e-learning platform eMediatheque %A Damien Cram %A Denis Jouvin %A Alain Mille %J STICEF %D 2007 %I %X This paper presents an interactive visualization tool for interaction traces, in the context of a synchronous collaborative e-learning activity. This tool has been developed by an e-learning company, eLyc¨¦e, in collaboration with a research team working on e-learning, interaction traces, and experience reuse. This work adopts the grounding hypothesis that metacognitive processes and reflexive activities can facilitate learning. The paper presents the specific issues of such usage trace construction and visualization, the design of the hosting collaborative synchronous platform, and the associated tools and underlying models properties. This tool has so far not been experimented with students, but the technical tests with various researchers have been very promising and encountered a wide acceptance. The paper also points out the generic aspects of the tracing mechanisms, and the possibility for the student, teacher and designer to configure, update and extend it dynamically %K Usage traces %K interaction traces %K synchronous collaborative platform %K e-learning %K interactive trace visualization %K reflexivity %U http://sticef.univ-lemans.fr/num/vol2007/06-cram/sticef_2007_cram_06p.htm
