Purpose: This study builds a new system for automatically assessing learners' speech elicited from an oral discourse completion task (DCT), and evaluates the prediction capability of the system with a view to better understanding factors deemed influential in predicting speaking proficiency scores and the pedagogical implications of the system.…

The introduction of Vygotsky's sociocultural theory (SCT) into the second language (L2) domain provides a potential site to explore the mechanisms underlying L2 learners' cognitive modification and the transformation of social understanding into the personal one. This study provided a picture of L2 personalization in two groups of advanced and…

Differentiated second/foreign language (L2) instruction (DI) has received growing attention in pedagogical research. Yet, as a cornerstone of inclusive education, the DI is still under-documented. In this study, we integrated diagnostic assessment (DIA) and collaborative language learning in a differentiated (tiered) oral tasks intervention and…

This study reports syllable position effects on second language (L2) Portuguese speech perception, revealing that L2 segmental learning may be prone to an influence from the suprasegmental level. The results show that first language (L1) Mandarin learners had diminished performance on the discrimination between the target Portuguese liquids (/l/…

Within the last two decades, researchers have begun to investigate how L2 learners process syntactic, morpho-syntactic, and lexical information during the comprehension of L2 sentences. The present study aimed to add to research by investigating how L1 influences L2 processing of sentences indicating plurality in constructions involving numerals.…

Substantial progress has been made toward applying technology enhanced conversation-based assessments (CBAs) to measure the English-language proficiency of English learners (ELs). CBAs are conversation-based systems that use conversations among computer-animated agents and a test taker. We expanded the design and capability of prior…

Recent technology advancements have increased the prospects for automated spoken language technology to provide feedback on speaking performance. In this study we examined user perceptions of using an automated feedback system for preparing for the TOEFL iBT® test. Test takers and language teachers evaluated three types of machine-generated…

Integrated speaking tasks requiring test takers to read and/or listen to stimulus texts and to incorporate their content into oral performances are now used in large-scale, high-stakes tests, including the TOEFL iBT. These tasks require test takers to identify, select, and combine relevant source text information to recognize key relationships…

L2 pragmatics have explored the effects of different factors on different aspects of learners' pragmatic performance, but often not simultaneously. In addition, syntactic complexity is rarely examined in L2 pragmatics. This cross-sectional study aimed to conduct a multidimensional analysis to explore the effects of proficiency and study-abroad…

Scholars debate whether musical and linguistic abilities are associated or independent. In the present study, we examined whether musical rhythm skills predict receptive grammar proficiency in childhood. In Experiment 1, 7- to 17-year-old children (N = 68) were tested on their grammar and rhythm abilities. In the grammar-comprehension task,…

As a branch of artificial intelligence, automated speech recognition (ASR) technology is increasingly used to detect speech, process it to text, and derive the meaning of natural language for various learning and assessment purposes. ASR inaccuracy may pose serious threats to valid score interpretations and fair score use for all when it is…

Adopting Linacre's guidelines for evaluating rating scale effectiveness, we examined whether and how a six-point rating scale functioned differently across raters, speech acts, and second language (L2) proficiency levels. We developed a 12-item Computerized Oral Discourse Completion Task (CODCT) for assessing the production of requests, refusals,…

This study uses both offline and online tasks in order to investigate whether second language learners of English from an article-less first-language (Mandarin) are able to integrate the indefinite article into their grammar despite the lack of articles in their first language. This article reports on two studies, one on learners' sensitivity to…

This study is the first to examine contributions of proficiency subskills to pragmatic development. We used the latent growth curve modeling to reveal the causal relationships between proficiency subskills and pragmatic competence in 109 American learners of Chinese across two data points over three months abroad in China. Proficiency was measured…

This book focuses on English as a Foreign Language (EFL) and provides advice on how to approach EFL teaching in the online context. Coronavirus has accelerated e-learning significantly and has highlighted the need of appropriate web tools that will allow teachers to present their material either synchronously or asynchronously, while also…
