For a discourse to thrive, its founding problematic has to be perceived as ‘real’ by its target audience – in this case, presumably, healthcare workers.
Real in this sense can be defined as something perceived to have an influence on foundational values, for better or for worse.
He goes on to distinguish the difference between a discourse community and a speech community.
Swales identifies a speech community as a group that shares similar linguistic goals, similar use of language, or both –as quoted by Hymes, “a community sharing knowledge of rules for the conduct and interpretation of speech” (470).
He then gives an example and discusses further issues regarding the concept of a discourse community.
To begin his argument, Swales touches on all of the past definitions of what a discourse community is.Together these features of ESP practice emphazise a situated view of literacy and underline the applied nature of the field.The teaching of literature has recently been resurrected as a vital component of English language teaching.In this chapter, I will briefly point to some of the major ideas and practices that currently influence ESP, focusing on needs analysis, ethnography, critical approaches, contrastive rhetoric, social constructionism, and discourse analysis.I then go on to look briefly at some of the effects ESP has had on language teaching and research, arguing that it has encouraged teachers to highlight communication rather than language, to adopt a research orientation to their work, to employ collaborative pedagogies, to be aware of discourse variation, and to consider the wider political implications of their role.Communication can be through text or confrontation.Information exchange is relative to the common goals.more The field of English for specific purposes (ESP), which addresses the communicative needs and practices of particular professional or occupational groups, has developed rapidly in the past forty years to become a major force in English language teaching and research.ESP draws its strength from an eclectic theoretical foundation and a commitment to research-based language education which seeks to reveal the constraints of social contexts on language use and the ways learners can gain control over these.In “The Concept of Discourse Community,” John Swales attempts to establish the true definition of a discourse community.Swales argues that there is a difference between a speech community and a discourse community and that there are six defining characteristics for a group to be a discourse community.
