Abstract
This paper shows how the organization of instruction including its design and sequential trajectories in a university laboratory and a boxing gym, is affected by the organization of participants' visual attention at that moment. Based on C. Goodwin (2003, 2006, 2007), we show that taking body position where participants can see each other or look at the same object, enables them to use multimodal resources such as gestures, in order to show and understand their own actions. We also demonstrate that what kind of sequential trajectory appears depends on whether participants can establish such joint attention.
