This review paper aims to provide an overview of vocabulary in English language learning, teaching, and testing in Vietnam. First, we review studies on the vocabulary knowledge of Vietnamese EFL learners. Recent research evaluating different aspects of vocabulary knowledge shows that Vietnamese EFL learners generally have limited knowledge of both…

This study investigated the effects of processing three types of texts, namely expository texts, narrative texts, and a combination of both known as twin texts, on incidental vocabulary acquisition and retention in L2 learners. College freshmen (N = 109), who were lower to upper intermediate learners of English, were assigned into a control group…

This paper reports on a quasi-experimental study that explored the differential effects of input- and output-based tasks on L2 vocabulary learning. The study adopted a pretest-posttest within-participants design, with sixty Vietnamese EFL university students. Participants in the experimental group completed four input and four output tasks in an…

The present study employed a mixed methods quasi-experimental design to investigate the effectiveness of applying motivational strategies and mental imagery (i.e. visionary techniques) to facilitate second language (L2) vocabulary learning. Four treatment sessions were integrated into a six-week language course offered to 150 intermediate students…

With the fast-paced development of technology in today's society, there has been emerging a shift from paper-based reading to digital online reading. While the benefits of exposure to print have been well-established in previous studies, how online reading may impact individuals' literacy development is largely underexplored. The current study…

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 paper explores how various teaching methods, namely Phonology-Based Instruction (PBI) and Translation-Based Instruction (TBI), have an effect on students' acquisition of formulaic sequences. 20 multiword expressions were taught to 48 Vietnamese EFL students from three intact classes as 2 treatment groups (PBI and TBI) and 1 control group.…

Mobile phone ownership among university students in Vietnam has reached almost 100%, exceeding that of Internet-capable desktop computers. This has made them increasingly popular to allow learners to carry out learning activities outside of the classroom, but some studies have suggested that learners are not always willing to engage in activities…

This article describes the development and validation of a Vietnamese bilingual version of the Vocabulary Size Test--a test which measures written receptive vocabulary size. The test can be used to measure the English vocabulary size of Vietnamese learners of English. A learner's total vocabulary size is calculated by multiplying their test result…

In Vietnamese secondary education, translation and visuals are traditionally used as major techniques in teaching new English lexical items. Responding to the Vietnamese government policy issued in 2008 on using IT for a quality education, the application of PowerPoint has been considered the most prevalent type of technology used in the…
