Developing a Corpus-Based Academic Word List for Welding Metallurgy ESP/EAP Courses(مقاله علمی وزارت علوم)
حوزههای تخصصی:
Employing reliable evidence-based academic word lists has been a noticeable concern for numerous educators, students, and researchers in English for Academic/Specific Purposes (EAP/ESP) courses. Currently, many of these courses still lack research-oriented materials and rely heavily on traditional ways of teaching field-specific terminologies. This study aimed to create a specialized corpus to identify the most frequent academic words in Welding Metallurgy (WM) and to analyze the most prevalent three- and four-word lexical bundles (N-grams). We employed a corpus-based approach, and identified top-tier journals of WM; then, we analyzed the articles from 2017 to 2023 that followed the Introduction, Methodology, Results, and Discussion (IMRD) format. As such, 875 empirical research articles were compiled and analyzed to establish a specialized corpus with four million words. After applying word selection criteria, 608 lemmas were identified. Furthermore, we recognized 68 technical acronyms in the field and grouped them into an independent list. We also highlighted the most prevalent N-grams to explore the field's formulaic language. Consequently, 61 prevalent technical N-grams were recognized. As part of pedagogical implications, this study would deepen ESP course instructors’ knowledge and urges them to be more mindful of evidence-based material. It also encourages students to give more weight to their fundamental discipline-specific needs by incorporating authentic word lists in practice.
