Abstract
Background: This study adopted a corpus-linguistics approach to investigate the gender effects in students' technical and scientific writing. Specifically, we analyzed whether gender influenced how males and females used adverbs (e.g., very, really, and definitely) and passive voice (e.g., the article was published in the journal). The overuse of both adverbs and passive voice has been associated with poor writing clarity and concision. Literature review: Previous research works on gender effects in language have been mixed. Since these are all the essential elements of effective technical communication, teachers need to know what gender effects might exist. Research questions are as follows: 1. Does gender influence the student writers' use of adverbs? 2. Does gender influence the student writers' use of passive voice? Methodology: The sample included 87 writers (46 females and 41 males) who contributed to a 757,533-word corpus. Researchers analyzed 12,111 instances of adverbs and 4,732 instances of passive voice within a variety of technical texts. Results/discussion: Female writers used significantly more adverbs as well as more additive/restrictive, degree, and stance adverbs than expected. Male writers used more linking and manner adverbs than expected. Female writers also used significantly more passives, particularly passive verbs associated with reporting findings and interpretation. In contrast, male writers associated with passive verbs used to describe methods and analyses. Overall, the results suggested that females and males used the same style markers to fulfill different rhetorical functions.
