    The characteristics of exchange structure patterns of an adult low-level ESL classroom using a genre-based approach to the teaching of writing : a study of classroom discourse
    Suherdi, Didi ( 1994)
    This study is concerned with the characteristics of exchange structure patterns of an adult low-level English as a second language (ESL) classroom using a genre-based approach to the teaching of writing in an Australian context. To provide an appropriate system of analysis, Ventola's (1987; 1988h) system for analysing conversational structure in service encounter texts has been expanded to suit the characteristics of the data in the current study. Applying the expanded version of Ventola's system, the whole data have been segmented into exchanges. Two major categories of exchange structure patterns have been identified: non-anomalous, which comprises simple and complex exchanges, and anomalous, which comprises elliptical, defective, and broken exchanges. Using this exchange categorisation as a basis, the characteristics of the interactional patterns, the shifts of roles of information supplier, and the variability of language use in a genre-based approach classroom have been identified and explicated. Exchange structure patterns dominant in certain sub-stages vary in accordance with the variation of other factors. In conjunction with the shifts of roles of the information supplier, for example, in Sub-stage 1, in which the students were cast to serve the function of information supplier, B-event exchanges were dominant, Only a small number of A-event exchanges occur in this sub-stage. In contrast, in Sub-stage 2 and Rehearsal where the teacher served the function of information supplier, A-event exchanges were dominant.
