The purpose of the current dissertation is to map the relationships between first language (L1), writing quality, and syntactic complexity, accuracy, lexical complexity, and fluency (CALF) in second language (L2) writing. CALF are characteristics of language production that have been of significant interest in L2 writing research for the past few…

Research on economic activity in Africa consistently ignores the importance of individuals' linguistic repertoires. We argue that an important contributing factor to the persistence of this lacuna is the lack of visibility of language in the social and economic data that is collected by governments through social surveys. We examine the specific…

Aural lexical knowledge (ALK) is crucial for second language (L2) listening. Despite its importance, there is scant research that has validly explored the relationship between ALK and L2 listening across different English as a Foreign Language (EFL) contexts. In an effort to broaden this research base, the current study closely replicates a…

Developmental difference is a common characteristic of autism spectrum disorder (ASD) with unclear sex differences. The current study included 610 children with ASD, aged between 2 and 7 years, with completed language profiles. We used a nonparametric item response theory model called Mokken scale analysis to examine the order of acquisition of…

As the first study addressing family language policy (FLP) in d/Deaf-parented families in China, the current research explores language ideologies, practices and management held by different members within the families. Children of d/Deaf adults (Codas) form an unusual bimodal bilingual group, and the study concerning this group prompts us to…

This study investigated how questioning strategies impact language learner performance. Specifically, it explored how questioning strategies influence (i) verb production and subject-verb agreement in the target language, and (ii) learner confidence in completing tasks without translation software. Sixty-eight novice language learners enrolled in…

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…

This is a longitudinal study of foreign language teacher professional identity development. We traced a single teacher's sociohistorical identity development at three temporally different moments during the first eight years of his teaching profession. The data, collected mainly through classroom observations and semi-structured interviews, were…

The partners of the Saudi students who come to the United States on scholarships to earn a degree (Bachelor's, Master's, or Ph.D.) are eligible for full scholarships as well. However, most of them fail to proceed in earning a degree or fulfill the language proficiency requirement needed to join an academic degree program. This study surveys…

Teaching language has challenges for many reasons, including learners' backgrounds, learning styles, motivation, and socio-economic status. However, EFL students can benefit from differentiation across the learning continuum to a large extent. This study investigated Afghan EFL learners' perceptions of differentiated instruction and the factors…

Background: Approximately 50% of all young children with a developmental language disorder (DLD) also have problems with speech production. Research on speech sound development and clinical diagnostics of speech production difficulties focuses mostly on accuracy; it relates children's phonological realizations to adult models. Contrarily to these…

This study examines whether children acquiring Tseltal (Mayan) demonstrate a noun bias -- an overrepresentation of nouns in their early vocabularies. Nouns, specifically concrete and animate nouns, are argued to universally predominate in children's early vocabularies because their referents are naturally available as bounded concepts to which…

Over decades, the body of research about the experiences and perceptions of prospective teachers of English during their teaching practicum has grown substantially. However, little research is currently available on the role of the wider educational context in shaping the TESOL practicum. The current study attempts to fill this gap by…

This duoethnography traces two transnational woman teacher-scholars' translanguaging pedagogies for equitable language and literacy education. Research on translanguaging has highlighted how lived experiences of transnational language and literacy educators crucially shape their language ideology, and professional identities and pedagogical…

Switching between languages requires the participation of executive functions (EFs) which comprise both the 'hot' affective aspects (hot EFs) and the 'cool' cognitive aspects (cool EFs). However, the role of these EFs in language switching is not clear. This study employed a word valence categorization task to explore the effects of hot (i.e.…
