Synchronization in demonstrations. Multimodal practices for instructing body knowledge

Abstract

Abstract Demonstrations are a central resource for instructing body knowledge. They allow instructors to provide learners with a structured perceptual access to the performance of an activity. The present paper considers demonstrations as inherently social activities, in which not only the instructor but also the learners may participate. A particular form of co-participation is that learners synchronize their own bodily actions with the demonstration of the instructor. The paper examines two practices of synchronization in demonstrations. In emergent synchronizations the instructor invites the student(s) to synchronize, rather than request them to do so. In orchestrated synchronizations teachers actively pursue the students’ bodily synchronization. The two practices are typically used for different instructional purposes. While emergent synchronizations are typically used in corrective instructions, orchestrated synchronizations are typically used to instruct new knowledge. Based on a large corpus of instructions in dancing Argentine Tango, the paper uses multimodal interaction analysis to characterize both practices regarding their interactional organization, their functional properties and the resources used by the participants to establish synchronization.
