The assessment encompasses essential concepts and their related measures about the information gathered. The conceptualization within a study becomes imperative to ascertain the corresponding variables and establish appropriate methodologies for their measurement. The willingness to communicate (WTC) concept, an individual's engagement in…

This book traces and summarizes the author's theoretical insights and empirical findings in the field of foreign language education. The volume explores themes such as individual differences in L1 ability and their connection to L2 aptitude and L2 achievement, L2 anxiety as an affective or cognitive variable, and the relationship between L1 and L2…

Purpose: We examined native language (L1) and second language (L2) convergence of underlying skills in adult L2 learners as well as the contribution of instructional L2 level on L2 attainment across speech motor, lexical, and narrative levels. Method: Thirty-four adult Spanish L2 learners who had completed at least 1 year of college Spanish…

In this study, 96 world language teachers in the state of Georgia completed a survey regarding their delivery of instruction in the target language. While ACTFL (2010, 2021) recommends using the target language 90% or more of the time to deliver instruction, only 20% of the world language instructors who were surveyed reported doing so. According…

This paper provides fresh insights on how PIs (Polarity Items) in non-veridical contexts (questions and conditionals) are represented in the grammar of multilingual learners of Catalan at different stages of development. It explores how this non-native grammatical system interacts with other previously acquired systems of negation and the implicit…

This study aims to provide a comprehensive profile of collocational competence, a key component of one's overall linguistic competence. For the maximum of ecological validity, we elicited naturalistic oral/written production data from 84 Chinese intermediate EFL learners and performed a 2×2 fashion of analysis on their performance in each of the…

This study investigated whether second language (L2) classroom instruction that incorporates a principled approach into the use of the first language (L1) by students and instructors has an effect on beginning learners' development of L2 speaking and writing proficiency, compared to L2-only instruction, over the course of one semester.…

In order to better understand the role of syntactic similarity in a code-switched sentence, the current study explored the effect of similar and different syntactic structures on Chinese-English bilinguals' intra-sentential switching costs. L2 proficiency and switching directions as factors that potentially intervene in bilingual performance were…

The effects of learner- and task-related variables on second language (L2) writing syntactic complexity (SC) have been extensively investigated. However, previous research has rarely assessed the reliability of computational tools for analyzing the SC of L2 spoken production, and we know less about the effects of such variables on L2 speaking SC.…

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…

Despite the widespread use and effectiveness of the Modern Language Aptitude Test (MLAT) composite score in predicting individual differences in L2 achievement and proficiency, there has been little examination of MLAT subtests, although they have potential for illuminating components of L2 aptitude and the mechanism of prediction. Here we use…

This study investigated how input frequency (i.e., type frequency and token frequency) and proficiency levels enhanced the perception of English nominal suffixes by first language (L1) Thai learners. Based on the Usage-based Account (Tomasello, 2003), it was hypothesized that input frequency, i.e., token frequency (frequency of derived forms…

The ACTFL Assessment of Performance Toward Proficiency in Languages (AAPPL, https://www.actfl.n.d.org/assessments/k-12-assessments/aappl) assesses proficiency in 11 languages for students in grades 3 to 12 and is often used to award the Seal of Biliteracy. While arguments for the valid interpretation and uses of the AAPPL have previously been…

English-medium instruction (EMI) has burgeoned alongside two decades of L2 self-regulated learning research. In both areas, listening remains under-researched, longitudinal designs are under-employed, and in-depth studies are necessary to unpack learner development. In a context believed to initiate self-regulated learning, the current study…

This study investigated the impact of student-selected pairs on emotional engagement and language-learning opportunities generated during collaborative tasks. Sixteen learners of English at a Hong Kong secondary school performed collaborative tasks in two pairing arrangements: student-selected pairing and teacher-assigned pairing (mixed…
