Verb argument constructions in argumentative essays by college-level Asian learners of English: Exploring the effects of English proficiency, acquisition context, and topic

Abstract

This study examined the effects of second language (L2) proficiency, acquisition context, and topic on the use of verb argument constructions (VACs) in Asian college-level L2 writers’ argumentative essays. A total of 776 essays written on two topics by 388 English as a Foreign Language (EFL) and English as a Second Language (ESL) writers of two L2 proficiency levels were used as data. Six indices informed by large-scale corpora of L1 English speakers were used to gauge the frequency and association strength of the VACs. Results of a series of linear mixed-effects models showed the frequencies of verbs and verb-construction combinations were affected by the interaction between L2 proficiency and acquisition context. L2 proficiency also had a main effect on construction frequency, with more proficient writers using constructions of lower frequency than less proficient writers. No effect of L2 proficiency was found on the association strength of VACs. Additionally, acquisition context affected the directional association strength of VACs, with ESL writers using verbs that associated less strongly with constructions than EFL writers. Finally, topic effects were found on five of the six indices. These findings offered empirical evidence for the developmental trajectories of VACs, and carried practical implications for L2 writing pedagogy.
