This study investigates the effects of three word-focused exercise conditions on vocabulary learning. The exercises were developed based on the involvement load hypothesis. This study also explores how individual differences (e.g. second-language English proficiency level and working memory) affect vocabulary learning outcomes. A total of 180…

Single word items have usually been the unit of analysis for measuring L2 learners' vocabulary size, for designing word lists and for estimating word coverage of reading texts. However, what is lost in these estimates is the consideration of multiword expressions, such as idioms. To empirically test the assertion that the knowledge of single word…

The study investigated L2 learners' perceptions of narrow reading. Thirty-two students finished four sets of graded readers organized by the same author with the same genre and same title, or random texts. After finishing each set of three graded readers, the students answered an eight-item questionnaire and wrote their reading feedback. Linear…

A great deal has been written about what English as an International Language (EIL) actually is (e.g. Alsagoff et al., 2012; Matsuda, 2012; McKay and Brown, 2016; Sharifian, 2009), ranging from a view of EIL as the many varieties of English that are spoken today to the use of English by second language speakers of English. Thus, EIL is viewed both…

This article provides preliminary validity evidence for the shorter Mandarin version of the Vocabulary Size Test (VST) under the content aspect, technical quality, substantive and generalizability aspect of Messick's (1995) construct validity framework. The shorter version with 177 Chinese university students in three proficiency levels indicates…

This study examines whether unfamiliar proper names affect English as a second language (ESL) learners' listening comprehension. A total of 110 intermediate to advanced ESL learners participated; comprehension of a short news text was tested under two conditions, Names Known (all proper names pre-taught in advance) and Names Unknown (all proper…

This paper reports an attempt to develop and validate a bilingual Persian version of the Vocabulary Size Test (VST). Due to the particular educational system in Iran, there is a dire need for a test that can effectively estimate English learners' vocabulary sizes. Previous research (Nguyen and Nation, 2011) has indicated that bilingual versions of…

Growing concerns have been voiced about strategies employed in L2 reading in general and dealing with unknown words in particular. Among other strategies, lexical inferencing has received attention in the literature. However, more research is needed to further clarify how different levels of L2 reading proficiency may affect the readers'…

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…

Language teachers often encourage L2 readers to guess the meaning of unknown words in texts. This paper argues that before any statements about the value of guessing can be made, it is necessary to show how reliable learners' guesses are. To this end, the present study investigates how accurately EFL learners assess their understanding of unknown…

The purpose of the current study was (a) to assess the effectiveness of the lexical-set (LS) and the semantically-unrelated (SU) vocabulary instruction, separately and relative to each other, and (b) to assess the differential effects of the two methods for students of lower and upper English proficiency levels. Two intact EFL classes were…
