Although there is abundant evidence for the use of first-language (L1) knowledge by bilinguals when using a second language (L2), investigation into the impact of L1 knowledge in large-scale L2 language assessments and discussion of how such impact may be controlled has received little attention in the language assessment literature. This study…

The last three decades have seen an increase of tests aimed at measuring an individual's vocabulary level or size. The target words used in these tests are typically sampled from word frequency lists, which are in turn based on language corpora. Conventionally, test developers sample items from frequency bands of 1000 words; different tests employ…

The knowledge about affix plays a vital role in the development of word knowledge and vocabulary acquisition. A test for diagnostic information on the level of affix knowledge would be useful in order to inform the test users of what learners have gained or lacked in this integral component of vocabulary knowledge. This paper reports the…

Instrument measurement conducted with Rasch analysis is a common process in language assessment research. A recent systematic review of 215 studies involving Rasch analysis in language testing and applied linguistics research reported that 23 different software packages had been utilized. However, none of the analyses were conducted with one of…

Nonverbal and other visual cues are well established as a critical component of human communication. Under most circumstances, visual information is available to aid in the comprehension and interpretation of spoken language. Citing these facts, many L2 assessment researchers have studied video-mediated listening tests through score comparisons…

Vocabulary's relationship to reading proficiency is frequently cited as a justification for the assessment of L2 written receptive vocabulary knowledge. However, to date, there has been relatively little research regarding which modalities of vocabulary knowledge have the strongest correlations to reading proficiency, and observed differences have…

This study compared three common vocabulary test formats, the Yes/No test, the Vocabulary Knowledge Scale (VKS), and the Vocabulary Levels Test (VLT), as measures of vocabulary difficulty. Vocabulary difficulty was defined as the item difficulty estimated through Item Response Theory (IRT) analysis. Three tests were given to 165 Japanese students,…

Cloze tests have been the subject of numerous studies regarding their function and use in both first language and second language contexts (e.g., Jonz & Oller, 1994; Watanabe & Koyama, 2008). From a validity standpoint, one area of investigation has been the extent to which cloze tests measure reading ability beyond the sentence level.…

The rise in the affordability of quality video production equipment has resulted in increased interest in video-mediated tests of foreign language listening comprehension. Although research on such tests has continued fairly steadily since the early 1980s, studies have relied on analyses of raw scores, despite the growing prevalence of item…

The primary purpose of this study was to provide preliminary validity evidence for a 140-item form of the Vocabulary Size Test, which is designed to measure written receptive knowledge of the first 14,000 words of English. Nineteen native speakers of English and 178 native speakers of Japanese participated in the study. Analyses based on the Rasch…

The present study investigated the effects of reducing the number of options per item on psychometric characteristics of a Japanese EFL university entrance examination. A four-option multiple-choice reading test used for entrance screening at a university in Japan was later converted to a three-option version by eliminating the least frequently…
