This study explored two assessment approaches to oral performances: analytical complexity, accuracy, and fluency (CAF) indices and human raters' evaluations. CAF indices are frequently used in second-language speaking (L2) research; however, because tasks are communicative and goal-oriented, the degree to which students achieve such communicative…

A perfect writing skill has been deemed instrumental to achieving competence in EFL, yet it is considered one of the most impressive learning domains. This study investigates the impact of human-AI collaborative feedback on the writing proficiency of EFL students. It examines key teaching domains, including the teaching environment, teacher…

This study examined how L2 English speakers interpreted the notion of native English speakers (NESs) and nonnative English speakers (NNESs) and whether nativeness would influence their self-perception and speech production. It aimed at filling the following research gaps. First, limited studies have explored how L2 English speakers view the other…

The rating of proficiency tests that use the Inter-agency Roundtable (ILR) and American Council on the Teaching of Foreign Languages (ACTFL) guidelines claims that each major level is based on hierarchal linguistic functions that require mastery of multidimensional traits in such a way that each level subsumes the levels beneath it. These…

It is general practice to use rater judgments in speaking proficiency testing. However, it has been shown that raters' knowledge and experience may influence their ratings, both in terms of leniency and varied focus on different aspects of speech. The purpose of this study is to identify raters' relative responsiveness to fluency and linguistic…

Many studies that have investigated the educational value of online machine translation (MT) in second language (L2) writing generally report significant improvements after MT use, but no study as of yet has comprehensively analyzed the effectiveness of MT use in terms of various measures in syntactic complexity, accuracy, lexical complexity, and…

This study compares the language proficiency gains of two groups of students taking a business English course module in a bilingual university in Catalonia (Spain). Whereas one of these groups followed a 'translanguaging' or 'plurilingual' pedagogy, the other followed a strictly monolingual approach. Participants were 54 mostly Catalan/Spanish…

This study was designed to determine how well existing analytic rating scales functioned in the assessment of low- to mid-proficiency Japanese university students' interactive English speaking ability when engaged in small group discussions. Many-facet Rasch measurement (MFRM) was employed to evaluate the quality of adapted rating scales for…

In this study, we examined whether interpreters and interpreting trainees are better predisposed to respeaking than people with no interpreting skills. We tested 57 participants (22 interpreters, 23 translators and 12 controls) while respeaking 5-minute videos with two parameters: speech rate (fast/slow) and number of speakers (one/many). Having…

The current study examined the extent to which native speakers of North American and Singapore English differentially perceive the comprehensibility (ease of understanding) of second language (L2) speech. Spontaneous speech samples elicited from 50 Japanese learners of English with various proficiency levels were first rated by 10 Canadian and 10…

In the present study we investigated the effect of test format on oral performance in terms of test scores and discourse features (accuracy, fluency, and complexity). Moreover, we explored how the scores obtained on different test formats relate to such features. To this end, 23 Iranian EFL learners participated in three test formats of monologue,…

The current study longitudinally examined the influence of aptitude on second language (L2) pronunciation development when 40 first-year Japanese university students engaged in practice activities inside and outside English-as-a-Foreign-Language classrooms over one academic year. Spontaneous speech samples were elicited at the beginning, middle,…
