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…

The measurement of second language (L2) productive lexical proficiency has driven a great deal of research over the past two decades. Research has indicated that more proficient speakers and writers tend to use a wider range of words and that more proficient writers tend to use words that are more sophisticated (less frequent in reference…

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…

In order to address the needs of the continually growing number of Chinese language learners, the present study developed and presented initial validation of a 100-item Chinese vocabulary proficiency test (CVPT) for learners of Chinese as a second/foreign language (CS/FL) using Item Response Theory among 170 CS/FL learners from Indonesia and 354…

Second language acquisition (SLA) in English can be revolutionized by artificial intelligence (AI) because it can provide personalized learning methods for learning English. Although AI has made advancements in this area, the standard SLA systems that are familiar with often fail to provide real-time, personalized feedback that can enhance…

The present study performs a three-level meta-analysis to investigate the overall effectiveness of automated writing evaluation (AWE) on EFL/ESL student writing performance. 24 primary studies representing 85 between-group effect sizes and 34 studies representing 178 within-group effect sizes found from 1993 to 2021 were separately meta-analyzed.…

To date there have been a lot of currently emerging studies focusing on English speaking anxiety experienced by Indonesian university students. Nevertheless, particularly the studies have not investigated university students in Lampung region as the new context. This study aims to describe the level, attitude and perception, and the causes of…

Learner corpus research has expanded from focusing primarily on English as a second language (L2) to include languages such as L2 Spanish, reflecting the growing importance of corpus linguistics in second language acquisition (SLA) research. In this context, and because prompts are the means by which learner corpora gather their texts, it has…

This study examined the influence of cognate status and language distance on simultaneous bilingual children's vocabulary acquisition. It aimed to tease apart effects of word-level similarities and language-level similarities, while also exploring the role of individual-level variation in age, exposure, and nontarget language proficiency. Children…

Digital reading facilitates L2 development by allowing anytime-anywhere learning with various digital resources. Although there has been increasing research exploring the role of digital reading on L2 vocabulary learning, synthesized evidence regarding the overall facilitating power of digital reading is still lacking. This meta-analysis…

This study investigated the effects of assisted oral reading on EFL learners' oral reading rates and took into account repetition times, passage features (length and type), and language proficiency. Forty-nine students from a university of technology took part in a 27-week oral reading program. Teaching assistants were assigned to assist…

Language negotiations facilitate second language acquisition (SLA) in both face-to-face (FTF) and computer-mediated interactions. Research shows that dyadic type can impact the quantity and quality of negotiations. Although both learner (L)-learner and native speaker (NS)-L dyadic type interactions have shown to be beneficial to SLA, it is still…

Drawing on a growing body of research on the interface between corpus linguistics and second/foreign language testing and assessment, we adopted "Peykare," a large-scale, annotated, Persian written language resource to evaluate the content (i.e., coverage and typicality) and construct validity of a Persian language proficiency test…

Different studies have demonstrated that people with dyslexia have difficulties in acquiring fluent reading and writing. These problems are also evident when they learn a second language. The aim of our study was to investigate if there is a linguistic transfer effect for writing in children with dyslexia when they face tasks in English (L2), as…

Using context to derive a word's meaning is typically conceptualized as part of the reading comprehension process. However, context sensitivity develops early--before children start to learn to read. This study took a developmental perspective, attempting to capture children's context sensitivity through spoken discourse and assess its value in…
