Research has demonstrated that features of lexical and lexicogrammatical use are important predictors of productive second language (L2) proficiency (e.g. Kyle et al. 2018). While some features of lexical use have been studied with L2s other than English (e.g. Tracy-Ventura 2017), multivariate lexical and lexicogrammatical approaches in these L2s…

Second language (L2) research on input manipulation has focused mainly on increasing the salience of target structures, but presentation formats of L2 input can be another important aspect for manipulation. This study compared the horizontal, vertical, and adjacent formats for presenting the characters, pinyin, and English meaning of L2 Chinese…

It is widely accepted that written corrective feedback (WCF) is an effective tool for helping learners develop their L2 knowledge. Yet, it remains inconclusive as to which type of WCF can best facilitate L2 learning. In recent years, many second language acquisition (SLA) researchers agree that "direct" and "focused" WCF may be…

The present study explored the processing units of high-proficiency second language (L2) Chinese learners in on-line reading in an eye-tracking experiment. The critical aim was to investigate how learners segment continuous characters into words without the aid of word boundary demarcations. Based on previous studies, the embedded words of 2- and…

Attaining Advanced proficiency and beyond has been a principal goal for second language learners, practitioners, and researchers. Achieving this level in writing requires producing connected discourse of paragraph-level length and nurturing the ability to arrange various linguistic units to form a unified and cohesive whole. This ability, known as…

Although lexical diversity is often used as a measure of productive proficiency (e.g., as an aspect of lexical complexity) in SLA studies involving oral tasks, relatively little research has been conducted to support the reliability and/or validity of these indices in spoken contexts. Furthermore, SLA researchers commonly use indices of lexical…

Derivational suffixes are known to play a crucial role in assigning stress to multi-syllabic words among native English speakers. However, it is unclear whether second language (L2) learners of English can effectively use derivational suffixes as stress cues in written words. To address this gap, we studied if native Chinese-speaking adults…

This study investigated the effect of synchronous computer-mediated communication (CMC) text chat and voice chat on Iranian EFL learners' oral proficiency and anxiety. To this aim, 81 Iranian pre-intermediate EFL learners were selected from among 125 students at private English language institutes. The selected participants were divided into two…

"How can teachers help students improve their second language (L2) speaking accuracy?" This is a question that most L2 educators ask themselves every day. Although L2 writing is a popular topic among Second Language Acquisition (SLA) researchers, the consideration that L2 writing has the potential to act as a scaffold for L2 speaking…

Given the lack of computational tools available for assessing second language (L2) production in Korean, this study introduces a novel automated tool called the Korean Syntactic Complexity Analyzer (KOSCA) for measuring syntactic complexity in L2 Korean production. As an open-source graphic user interface (GUI) developed in Python, KOSCA provides…

This article introduces the CELI corpus, a new learner corpus of written Italian consisting of ca. 600,000 tokens, evenly distributed among CEFR (Common European Framework of Reference for Languages) proficiency levels B1, B2, C1 and C2. The collected texts derive from the language certification exams administered by the University for Foreigners…

The purpose of this work was to address the overarching questions of how EFL Thai learners preferred corrective feedback strategies and whether there were any significant differences in preferences across learners' language ability levels. The quantitative study collected 418 Thai EFL learners' preferences for corrective feedback via a…

This study aimed to examine the acquisition of Roman alphabetic script among young children within a bilingual (Arabic and English) educational environment employing a language separation pedagogical approach in Muscat, Oman. Data were collected utilizing participant observations, video recordings to capture the interactions of three children and…

This study builds upon previous research investigating the construct validity of phraseological complexity as an index of L2 development and proficiency. Whereas previous studies have focused on cross-sectional comparisons of written productions across proficiency levels, the current study compares the "longitudinal" development of…

The relationship between written and spoken recall (SR) has primarily been analyzed with English-speaking monolinguals. Written recall (WR) has been reported more accurate due to higher cognitive load and attention required to produce a text. This study examined the written and spoken text recall relationship in L2 learners of Russian and analyzed…
