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 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 purpose of this study is to analyze the grammatical complexity features of international teaching assistants' (ITAs) mock-teaching presentations and to compare the distributions of these features to those found in the Oral English Proficiency Test (a local ITA assessment), university classroom teaching, conversation, and academic writing. The…

Language is inherently variable, and learner language is particularly variable. The variationist paradigm considers learner language a heterogeneously variable yet inherently rule-governed system. Specifically, learners' alternation between native-like and nonnative-like variants of a variable or invariable target native speaker (NS) form…

This study attempts to explain a systematic phenomenon that has been described in interlanguage grammars crosslinguistically: Null-Prep, which consists of omitting the obligatory preposition in certain movement constructions. We propose that Null-Prep is not related to lack of knowledge of "wh"-movement, as previously assumed, but to…

The Spanish subjunctive mood (SUBJ) is said to be highly vulnerable in heritage language (HL) acquisition. However, there is little controlled research on HL-speaking children acquiring the various Spanish SUBJ contexts, so we do not have a clear picture of when, how, or why heritage speakers (HSs) develop in the SUBJ as they do. This study tests…

Although there is consensus that collaboration refers to two or more learners working together to accomplish a task (Davin & Donato, [Davin, K., 2013]; Ohta, [Ohta, A., 2001]), debate remains about how to assess collaboration. Researchers have pursued two approaches to evaluate collaboration during peer interaction: rater judgments (e.g.,…

In the present study, we take a longitudinal, corpus-based perspective to investigate short-term (over 9 months) linguistic change in the language produced for the spoken and written sections of the "TOEFL iBT"® test by a group of English-as-a-foreign-language (EFL) learners in China. The goal of the study is to identify patterns that…

This study investigated the role of corrective feedback timing in the acquisition of Spanish noun--adjective gender agreement. Forty-five learners completed a communicative task via synchronous computer-mediated communication (SCMC) in one of three groups (immediate, delayed, control). The immediate-feedback group received error reformulations…

This study investigates whether gestures can be used during recasts to enhance the saliency of a target structure (locative prepositions) and to lead to better production of the target structure. Forty-eight low-intermediate English as a second language (ESL) students partook in communicative activities during which they received either no…

This study launched an investigation into the extent to which textual enhancement in captions can promote learner attention to and subsequent development in second language (L2) grammar. Using eye-tracking, it also intended to extend research on the relationship between attention and L2 learning. A pretest-posttest experimental design was…

This study investigates the referential choice of Mandarin-speaking children with autism spectrum disorder (ASD). The data consist of narratives from 16 children with ASD and 16 typically-developing (TD) children. The narratives were elicited using the wordless picture book "Frog, where are you?" Participants' referential expressions…

This study used elicited production methodology to investigate the negative sentences that are produced by English-speaking children with specific language impairment (SLI). Negative sentences were elicited in contexts in which adults use the negative auxiliary verb doesn't (e.g., "It doesn't fit"). This form was targeted to see how…

Investigations of the validity of a number of high-stakes language assessments are conducted using an argument-based approach, which requires evidence for inferences that are critical to score interpretation (Chapelle, Enright, & Jamieson, 2008b; Kane, 2013). The current study investigates the extrapolation inference for a high-stakes test of…

The present study investigates whether the implementation of a dictogloss task within a proactive Focus on Form approach (e.g., Long 1991; Long and Robinson 1998) has significant effects on the acquisition of Spanish present subjunctive. A total of sixty-six learners in a fifth-semester Spanish course participated in the study and were assigned to…
