This study explores the extent to which the difficulty levels of grammar items in an English test can be predicted by the complexity of grammatical structures. The researchers carried out two sets of analyses. In the first analysis, the item facility and item discrimination indices of 175 multiple-choice items were examined. In the second…

This study aims to investigate ChatGPT's ability to comprehend input from nonnative speakers, specifically those learning English as a second language, with Japanese speakers serving as the model population. The experiment examines how ChatGPT evaluates the difficulty levels of the Test of English for International Communication (TOEIC), which is…

This dissertation investigates the interplay between the implicit knowledge that learners have of a nonnative language and their processing of that language, examining two types of relative clauses (RCs) in English: gapped RCs (e.g., "the man that they hired") and resumptive RCs (e.g., *"the man that they hired him").…

This study is aimed to identify the effects of task complexity on first language (L1) use and the functions it may serve when two groups of learners of English as a foreign language (EFL) work on collaborative tasks. Twenty-four pairs of Chinese EFL learners from two universities were assigned to a lower-proficiency and a higher-proficiency group,…

According to the IELTS official website, IELTS candidates usually score lower in the IELTS Writing test than in the other language skills. This is disappointing for the many IELTS candidates who fail to get the overall band score they need. Surprisingly enough, few studies have addressed this issue. The present study, then, is aimed at shedding…

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…

Form-Focused Instruction (FFI) has been extensively studied, yet past experimental results are often inconsistent or even contradictory. Overly simplistic examinations of grammatical complexity and learner characteristics (e.g., L2 English proficiency) may have fueled the confusion, limiting understanding of how different FFI techniques can be…

Researchers have recommended that English-as-foreign-language (EFL) classrooms should use lexically easy short poems. However, no studies have examined EFL learners' actual reading processes for these poetry texts, the insights of which are vital for corroborating future poetry-teaching methods. Hence, this study investigates how…

In successful writing development, English as a foreign language (EFL) learners not only need to acquire grammatical complexity (GC) features but also know when and how to use them flexibly across communicative contexts, known as register flexibility. The present study, guided by the sociocultural theory of language learning, examines descriptive…

Recently, researchers have expressed their growing concern over the scrutiny of language test items in light of cognitive load theory (CLT). While cognitive load has been central to language learning research, it has not enjoyed due attention in high-stakes language tests. The current study set out to delve into the relationship between difficulty…

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…

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…

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…

Previous studies have been done to research the effects of different electronic feedback (e-feedback) modes of helping English as a foreign language (EFL) students improve their writing. The purpose of this study was to employ online peer feedback (OPF) and automated corrective feedback (ACF) to assess EFL learners' writing performance in the…

This study investigated the involvement of the Social Agency Theory within a multimedia learning environment to improve English language proficiency. The primary aim of this study is to find the effects of designing language learning instructional videos following the embodiment principle on language learners' motivation, cognitive load and…
