The Multimodal Mediation of Knowledge: instructors' explanations in a scientific café
Résumé
In this paper, we present an in depth study of the interplay between various semiotic modes in the specific instructional setting of a scientific café. We analyzed the multimodal performance of five female instructors delivering a monologue explanation during instruction on the following dimensions: speech, gesture (hand gestures, head orientation and gaze) and use of written didactical material. Results first point out the crucial role played by referential hand gesture together with gaze-body behavior both in representing new concepts (conceptual mediation) and in building bridges between information displayed in several modes (semiotic mediation). They also show crossindividual differences in instructors' multimodal performance, that we propose to interpret as three diverse modes of mediating knowledge, guiding being the only one providing both conceptual and semiotic mediation.
