'Context' is a concept for linguistic analysis which has rarely been subjected to close empirical scrutiny. This volume presents an attempt to investigate in microscopic detail various processes of contextualization by which children organize their interaction 'frame by frame', achieve, sustain, and embody their working consensus on what it is that they are doing together, and thereby situate their linguistic activities. Microethnography comprises research methods of context analysis, ethnography, and conversational analysis and seeks to locate phenomena of social order in both verbal and nonverbal behavior.
