Recently researchers have proposed using information from teachers and learners to supplement the information from corpora in the selection of the most useful words for foreign language learners. Yet the extent to which these data sets correlate to one another is unclear. This study explicitly investigated the relationships between (a) the lexical…

This article examines the use of prompt-based lexical collocations in opinion essays by Vietnamese English as a foreign language (EFL) students. Fifty second-year English majors at a Vietnamese university wrote 100 opinion essays on two topics as progress tests. The AntConc programme (Anthony, 2020) was employed to identify the frequencies of use…

Data-driven learning (DDL) is an increasingly popular area of research for language teaching and is gradually being incorporated into teacher education programs globally. However, assessing teacher trainees' (self-reported) corpus literacy, and its impact on eventually (and successfully) incorporating corpora into language teaching, is an ongoing…

Word frequency has a long history of being considered the most important predictor of word difficulty and has served as a guideline for several aspects of second language vocabulary teaching, learning, and assessment. However, recent empirical research has challenged the supremacy of frequency as a predictor of word difficulty. Accordingly,…

The rapid development of high technology and the Internet has made online learning increasingly popular, especially in the last few years when the COVID-19 pandemic appeared and spread worldwide. However, implementing online English courses in the pre-COVID-19 period was not prevalent; and only a few courses utilized new technologies to teach the…

In recent years, the use of English corpora to instruct grammar in writing classes has become increasingly popular. In English for Specific Purposes classes, such a novel approach is critically important since it not only allows teachers to achieve a profound understanding of which syntactic structures should be instructed, but it also increases…

This study investigated Vietnamese EFL learners' knowledge of verb-noun and adjective-noun collocations at the first three 1,000 word frequency levels, and the extent to which five factors (node word frequency, collocation frequency, mutual information score, congruency, and part of speech) predicted receptive knowledge of collocation. Knowledge…

The significance of errors in explicating Second Language Acquisition (SLA) processes led to the growth of error analysis in the 1970s which has since maintained its prominence in English as a second/foreign language (L2) research. However, one problem with this research is errors are often taken for granted, without problematising them and their…

This article presents selective findings from an ongoing study that investigates rhetorical differences in business letter writing between Vietnamese students taking an English for Specific Purposes course in Vietnam and business professionals. Rhetorical analyses are based on two corpora, namely, scenario (N = 20) and authentic business letters…
