The study explored the correlation between teaching lexical bundles and improving writing skills in English composition courses. The study addressed two research questions. First, to what extent can the explicit teaching of lexical bundles facilitate greater comprehension and retention of the elements of the bundles? Second, the study investigated…

This study investigates the influences of early and intense L2 exposure on children's L1 causative verb production, assessed by an experimental causative verb production task. Turkish expresses causality by morphological and lexical means, whereas English does so by periphrastic and lexical means. Learning L2 English might enhance L1 Turkish…

Domestic immersion (DI) is an effective context for postsecondary language learning, given that DI's instructor-curated environments promote meaningful second language use while providing abundant support for learners. However, DI is at present understudied within second language acquisition research, especially when compared to its more…

This study investigates the effects of pre-task planning on English as a second language (ESL) learners' engagement in oral tasks in the face-to-face real-time communication (FTF) and synchronous video-based computer-mediated communication (SvCMC) modes. A total of 36 ESL learners performed two decision-making tasks (with versus without pre-task…

While formal L3 morphosyntactic acquisition research has focused on the roles of the L1 versus L2 during the L3 initial stages, we examine their roles during development. Specifically, we explore whether the L3 (here, Portuguese) revision process after non-facilitative transfer differs whether the initial L3 representation reflects the L1 or L2.…

The main goal of this tutorial is to promote the study of children with developmental language disorder (DLD) across different languages of the world. The cumulative effect of these efforts is likely to be a set of more compelling and comprehensive theories of language learning difficulties and, possibly, of language acquisition in general.…

The issues of depth vocabulary knowledge and Willingness to Communicate (henceforth, WTC) are among the most important issues in second language learning. The present study set out to empirically look into the contribution of WTC to depth of vocabulary knowledge in L2 learning. To this end, 88 English L2 learners, divided into two groups in terms…

Relative clauses (RCs) are complex syntactic structures because they consist of multiple clauses and involve syntactic movement. RCs are known as a reliable clinical marker of syntactic impairment across many different languages and populations. Children with autism spectrum disorders (ASD) struggle with the comprehension and production of RCs,…

This study investigates the effects of Processing Instruction (PI) on the acquisition of grammatical gender and gender-marked pronouns in German. PI was compared to Traditional Instruction, i.e. a traditional, vocabulary-oriented approach using color cues (TI) and a Categorization and Memorization task (CM). The results of an immediate posttest…

With the growing interest in integrating information and communication technology in the EFL classroom, the present study investigated the impact of electronic first language (L1) translations and second language (L2) definition glosses on incidental vocabulary learning and retention among Moroccan EFL learners. In total, 172 first-year university…

In this mixed-methods study, we investigated the relationship between instructional approach, students' self-efficacy beliefs, and students' English language proficiency, as well as the perceptions of the instructor and students regarding problem-based learning (PBL) in a College English course in China. Using path analysis, we assessed the…

Assessing vocabulary knowledge is an important part of establishing language proficiency in bilingual children. The crosslinguistic lexical tasks (CLTs) provide a framework for testing vocabulary development in three-to-six year-olds using a standard procedure and comparable items for multiple languages. This study describes the development of the…

Background: Although students in teacher education programmes in Namibia study through the medium of English, their academic language (AL) proficiency remains a challenge for most of them. In the Junior Primary Education programmes, they are not only required to master AL for their own studies, but they must also learn how to teach emergent…

This study examined the significance of the mode of delivery--aural versus written--in second language (L2) vocabulary knowledge and L2 comprehension skills. One of the unique aspects of listening comprehension that sets it apart from reading comprehension is the mode of delivery--language input is delivered not visually but aurally. Somewhat…

This dissertation is about the learnability of different generative, Separationist approaches to nominal morphosyntax. The core of my investigation is number, gender, and declension class, as manifested across nouns, adnominals (adjectives, numerals, demonstratives, and quantifiers), and articles. An extreme position would require that all of…
