The way in which validity has been conceptualized has changed throughout the years. The focus in validation studies shifted from evaluating distinct components of validity to developing a comprehensive argument for the use and interpretations of test scores. The argument-based approach to validity incorporates the distinct types of the…

With the increasing interest in Positive Psychology within the realm of L2 learning, the role of positive emotions, particularly Foreign Language Enjoyment (FLE) has garnered attention in Second Language Acquisition research (Dewaele & MacIntyre, 2014). Despite the growing interest in FLE in Turkey, the widely used Foreign Language Enjoyment…

This study examines how second/foreign language (L2) word difficulty estimates derived from item response theory (IRT) and classical test theory (CTT) frameworks are virtually identical in the context of vocabulary testing. This conclusion is reached via a two-stage process: (a) psychometric assessments of both approaches and (b) L2 word…

Several high-stakes English proficiency tests including but not limited to IELTS, PTE Academic, and TOEFL iBT recommend a 2-year time limit on validity for score usage. Although this timeframe provides a useful rule-of-thumb for the recency of testing, it can have far-reaching consequences. In response to stakeholder queries around IELTS validity…

The growing diversity among test takers in second or foreign language (L2) assessments makes the importance of fairness front and center. This systematic review aimed to examine how fairness in L2 assessments was evaluated through differential item functioning (DIF) analysis. A total of 83 articles from 27 journals were included in a systematic…

Foreign language classroom anxiety (FLCA) is a popular construct in applied linguistics research, traditionally measured with the 33-item Foreign Language Classroom Anxiety Scale (FLCAS). However, recent studies have started utilizing the eight-item Short-Form FLCAS (S-FLCAS). There is therefore a need, which this study addressed in five…

C-Test is a gap-filling test designed to measure first and second language proficiency. Over the past four decades, researchers have shown the fit of C-Test data to parametric item response theory (IRT) models, but no study so far has shown the fit of C-Tests to nonparametric IRT models. The purpose of this study is to contribute to the ongoing…

Rating scales that language testers design should be tailored to the specific test purpose and score use as well as reflect the target construct. Researchers have long argued for the value of data-driven scales for classroom performance assessment, because they are specific to pedagogical tasks and objectives, have rich descriptors to offer useful…

The study aims to develop and validate an affordable and generalizable survey design tool to measure pre-service EFL teachers' self-efficacy beliefs about cultural and linguistic diversity. It is significant as there are relatively low number of studies aiming to measure such beliefs in today's changing demographic conditions which are beyond its…

Since Gisela Granena's influential work, LLAMA D v2, a sound recognition subtest of LLAMA aptitude tests, has been used as a measure of implicit learning aptitude in second language acquisition research. The validity of this test, however, is little known and the results of studies with this instrument have been somewhat inconsistent. In this…

Language assessment is a central aspect not only of language education in the general population, but also amongst heterogeneous, low-incidence populations. One such population are immigrant deaf and hard-of-hearing learners (IDML) who are bimodal-multilingual and whose languages development often includes the spoken, written, and/or signed…

Lexical diversity (LD) is an important indicator of second language lexical development. Much research has investigated LD indices, with a focus on learners of English. However, further research is needed in languages that are typologically distinct from English, such as Korean. In this study, we evaluated the reliability and validity of LD…

The study seeks to conceptualise foreign language learning burnout and provide its corresponding measurement. The 15-item "Maslach Burnout Inventory-Student Survey" (MBI-SS) was rephrased to fit an English-as-a-Foreign-Language (EFL) learning context. The modified MBI-SS was then assessed among 1718 Chinese secondary EFL students. A…

Chulalongkorn University Language Institute (CULI) test was developed as a local standardised test of English for professional and international communication. To ensure that the CULI test fulfils its intended purposes, this study employed Kane's argument-based validation and Rasch measurement approaches to construct the validity argument for the…

As survey research in second language acquisition grows in popularity, the adherence to best practices associated with questionnaire quality is critical for a better understanding of factors that influence second language (L2) development. To ensure that a self-report scale targets the construct of interest and does it consistently and accurately,…
