Comparing lexical bundle use in EAP reading textbooks to lower-division university textbooks
This study employed a corpus analysis to describe differences in lexical bundle patterns between English for academic purposes (EAP) reading textbooks and lower-division university textbooks by focusing on three characteristics: (1) the frequency of occurrence of bundles, (2) the frequency of bundle structures (e.g., phrasal vs. clausal), and (3) the frequency of bundle discourse functions (e.g., stance, discourse organizers, and referential; see Biber et al., 2004; Biber, 2006). Results revealed that the corpus representing lower-division university textbooks employed more passive bundles, intangible framing bundles, and text deixis bundles. On the other hand, the corpus representing EAP reading textbooks contained more prepositional phrase bundles, anticipatory it bundles, and place bundles. A qualitative comparison also revealed that quantity bundles in the corpus representing lower-division university textbooks made reference to technical and academic calculations. These results show how the communicative purposes of EAP reading textbooks differ from introductory university textbooks, which can be used to inform EAP reading instruction.
