Abstract
Abstract The present study compared 4-word lexical bundles found in a general engineering corpus (2,030,000 words) with those found in a corpus of texts collected from a Pathway engineering course for ESL (English as a Second Language) students (356,000 words) and a corpus of pedagogical materials used to teach advanced ESL students at an intensive English program (440,000 words). The results indicated that the structural and functional characteristics of the lexical bundles in the Pathway engineering materials were representative of the discourse features found in the general engineering corpus. This finding provides additional evidence of the overall appropriateness of the pedagogical materials selected for the Pathway course. Furthermore, the two engineering corpora also included a substantial number of bundles that were unique to the specific course materials, and, therefore, can potentially be targeted during language instruction.
