Discoursing disciplinarity: A bibliometric analysis of published research in the past 30 years

Diverging from the long-held homogeneous view of academic discourse, the issue of disciplinarity has come to the forefront in EAP teaching and discourse analysis. Although disciplinary discourse is a well-established and expanding line of inquiry, there has been limited retrospective analysis to unpack its evolutionary nuances. This bibliometric study maps its evolution from 1990 to 2022, tracing its journey from a fringe component within applied linguistics and language pedagogy to a globally recognized field. Using 921 articles retrieved from the Web of Science's core collection, our analysis reveals enduring scholarly interest in disciplinary literacy, writing, and socialization, with a marked shift since 2006 towards exploring the interplay between disciplinary knowledge-making practices and interpersonal features, such as stance, identity, and function. These studies, often using corpus approaches, highlight how these themes both reflect and are shaped by the disciplinary epistemology and ideology inherent in communities of practice. Emerging areas include student writing, spoken English, multimodal resources, and the temporal and interdisciplinary dynamics in various disciplines. The diverse authorship and geographical sources across various fields further underscore the global relevance of these topics. This overview could serve as a valuable resource for researchers, educators, and practitioners navigating this dynamic and significant field.
