ABSTRACT
Chapter Four demonstrates a way to filter data by tracking three sources of expectations that flow into a nexus: interaction orders, historical bodies, and discourses in place. This chapter addresses an ongoing challenge for any nexus analyst: shaping and reshaping the research focus to stay responsive to the fluid goals and concerns of participants (in this case, the teachers and children in primary school classrooms). This chapter demonstrates how a filtering process organized by the three circulating flows can focus a large set of ethnographic video data, from the initial search for a play-based literacy-rich site of engagement to selection of key moments for closer analysis.
