Second language acquisition (SLA) researchers have long searched for patterning in the development of linguistic elements (e.g., grammar and morphology). However, little attention has been given to the examination of systematicity in vocabulary acquisition, limiting our understanding about how overall vocabulary is learnt. The current study…

In response to calls for an assessment tool that provides a separate performance dimension from the linguistic quality-oriented measures of complexity, accuracy, and fluency (CAF) and guided by systemic functional linguistic (SFL) theories, this study introduces a set of fine-grained objective measures of communication/content/function…

Complexity, accuracy, and fluency (CAF) as measures of language proficiency have been used extensively in assessing second language production in English language studies related to task-based language teaching. The present review adds the following critical elements to the existing body of literature: (i) Provides synthesis and critical analysis…

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…

Peer feedback has been widely used in English as a foreign language (EFL) writing classes, but its effect is highly variable and its quality and validity are often questioned by students as well as teachers. This research aims to explore the effects of teacher intervention on student use of different types of peer feedback and on their…

There is a lack of tests available for assessing sign language proficiency among L2 learners. We have therefore developed a sign repetition test, SignRepL2, with a specific focus on the phonological features of signs. This paper describes the two phases of developing this test. In the first phase, content was developed in the form of 50 items with…

Making adults learn from larger linguistic units can facilitate learning article-noun agreement. Here we ask whether initial exposure to larger units improves learning by increasing the predictive associations between the article and noun. Using an artificial language learning paradigm, we taught 106 Hebrew-speaking participants novel article-noun…

We investigated whether learning and retaining vocabulary in a second language (L2) can be improved by leveraging a combination of memory enhancement techniques. Specifically, we tested whether combining retrieval practice, spacing, and related manipulations in a 'multidomain' pedagogical approach enhances vocabulary acquisition as compared to a…

Previous research has shown that task repetition can positively affect L2 oral performance. However, few studies have explored the effects of task repetition on young EFL learners' production. Also, task repetition research has paid little attention to effects of "spacing" examined through longer time intervals between the two occasions…

This quasi-experimental study investigates the effects of pre-writing (Pre-EI) and post-writing explicit instruction (Post-EI) on L2 learners' overall writing accuracy and errors at different severity levels. Situated within process-genre-oriented writing classrooms, a total of three intact groups (N = 101) were designated as two experimental…

This paper evaluates the use of Factor Analysis (FA) in English education research in Korea and suggests improvements in methodology. A detailed coding protocol was used to review 179 FA cases from 12 major English education journals (2014-2023). The review identified several key issues, including small sample sizes and lenient criteria for sample…

Language learning activities involving time-pressured repetition of similar content have been shown to facilitate improvements in fluency. However, concerns have been voiced about whether these gains might be offset by reduced levels of grammatical accuracy. This descriptive study tracked the oral proficiency of 32 Japanese university students…

Language testing research has suggested that placement accuracy can be an important factor in the consequences of placement decision-making. However, previous studies primarily have used a one-shot teacher judgment of placement accuracy, suffering from a lack of students' perspectives of their time-varying experiences. The present study aimed to…

In this study, I compare the accuracy of automatic speech recognition (ASR) transcription against two measures of intelligibility provided by human listeners. The data came from readings of five texts recorded by 15 language learners of French. Human understanding was gauged by (i) asking a group of 36 naïve first language (L1) speakers of French…

Machine translation (MT) is the automated process of translating text between different languages, encompassing a wide range of language pairs. This study focuses on non-professional bilingual speakers of Turkish and English, aiming to assess their ability to discern accuracy in machine translations and their preferences regarding MT. A particular…
