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…

Although the TOEFL iBT Listening test is sometimes used for other purposes, it was designed primarily for use as a college entrance examination. Item difficulty in TOEFL iBT Listening tests is the product of interactions between two sets of complex relationships: 1) relationships among numerous item characteristics themselves, and 2) relationships…

The current paper intends to exploit the Many Facet Rasch Model to investigate and compare the impact of situations (items) and raters on test takers' performance on the Written Discourse Completion Test (WDCT) and Discourse Self-Assessment Tests (DSAT). In this study, the participants were 110 English as a Foreign Language (EFL) students at…

Language proficiency policies act as critical gatekeepers for multilingual international students (MIS) who intend to pursue an education at English-medium universities. The current study revisits the question of the predictive validity of a standardized English proficiency exam--International English Language Testing System (IELTS)--in comparison…

This study examined the relationship of linguistic complexity, captured using a set of lexical richness, syntactic complexity, and discoursal complexity indices, to second language (L2) learners' perception of text difficulty, captured using L2 raters' comparative judgment on text comprehensibility and reading speed. Testing materials were 180…

Chinese directional complement (DC) constructions, as a subtype of Chinese multiword sequences, are challenging to acquire for second language (L2) learners. However, little is known about L2 Chinese learners' acquisition of figurative DCs and their comprehension of literal and figurative DCs. This study investigated whether the acquisition of…

Scheduling of practice to create a spacing effect has been observed to lead to superior retention of L2 vocabulary and grammar. Two of the various methods of scheduling L2 task practice discussed widely in recent times are interleaving and blocking. In a desirable difficulty framework, both of these methods have been recommended for task…

This study employed a multi-methods design to investigate the impact of preparation on Chinese test-takers' perceptions of the integrated TOEFL iBT speaking and writing design. Combining results from over 1700 surveys and 10 interviews, it was found that these Chinese test-takers, who are the most vulnerable group in the multimillion testing…

The aim of this experiment was to investigate how glossing influences second language (L2) reading comprehension in relation to text difficulty and the two local and global meaning representations. Fifty-eight undergraduate students were asked to read three easy, moderate, and difficult texts and, following each passage, answer twenty…

Estimating the difficulty of reading tests is critical in second language education and assessment. This study was aimed at examining various text features that might influence the difficulty level of a high-stakes reading comprehension test and predict test takers' scores. To this end, the responses provided by 17,900 test takers on the reading…

The digital transformation in educational assessment has led to the proliferation of large-scale data, offering unprecedented opportunities to enhance language learning, and testing through machine learning (ML) techniques. Drawing on the extensive data generated by online English language assessments, this dissertation investigates the efficacy…

The increasing popularity of the Common European Framework of Reference (CEFR) in non-native English-speaking countries has generated a demand for concrete examples in the creation of CEFR-based tests that assess the four main English skills. In response, this research endeavors to provide insight into the development and validation of a…

The present study sets out to measure Turkish EFL learners' receptive affix knowledge and productive derivative vocabulary knowledge. More specifically, the extent to which Turkish EFL learners recognize written form of affixes, know the meaning of affixes and determine the part of speech of the derivatives produced by means of affixes and how…

Despite being a popular topic in language testing, cognitive load has not received enough attention in vocabulary test items. The purpose of the current study was to scrutinize the cognitive load and vocabulary test items' differences, examinees' reaction times, and perceived difficulty. To this end, 150 students were selected using…

Dative alternation between prepositional and double object datives has been a popular topic in second language (L2) acquisition, but only few studies deal with discourse constraints such as the "given-before-new" principle, or given-new (GN) ordering, which describes the tendency to place given information before new information. The…
