Since corpus linguistics gained popularity as a methodology in the latter half of the 20th century, second language acquisition research has seen the emergence of work investigating formulaic language, such as idioms, lexical bundles, and collocations. A collocation is a string of words that co-occur more routinely than probability would predict,…

This mixed methods study draws upon theoretical perspectives from usage-based linguistics (UBL) and variationist sociolinguistics to explore four learners' use of second language (L2) Spanish present tense indicative verbal inflectional morphology (i.e., simple present conjugations). The study compares the frequency and distribution of students'…

Relative clause (RC) production is an important language milestone for children. Incorporating a felicitous context when assessing RC production is of theoretical and clinical value. This study investigated how a felicitous context influenced elicited production of RCs from monolingual English-speaking and bilingual Mandarin-English speaking…

Native Arabic speakers used idiomatic expressions such as idioms, formulas, and collocations, in their daily communications. In learning Arabic as a second language (L2), effective communication requires "the ability to understand and use idioms appropriately and accurately in a variety of sociocultural contexts, in a manner like that of…

This study examined the differences and similarities among the writing of three types of developmental English and advanced ESL United States community college students, comparing the writing of resident English learners (RL2), whose home language was not English but who attended United States public schools for five years or more, to that of…

Just as pronouns like "she" and "he" make anaphoric reference to individuals, English words like "that" and so can be used to refer anaphorically to a proposition introduced in a discourse: "That's true; She told me so". Much has been written about individual anaphora, but less attention has been paid to…

Learning to use prepositions in English as a second language (L2) has been widely acknowledged to pose significant difficulties to learners, especially within metaphorical contexts. Difficulties relate to the complex distributional patterns of prepositions in discourse, namely, the variety of collocations requiring their use, as well as…

Conceptual Metaphor (CM; e.g., Lakoff & Johnson, 1980, 1999; Kovecses, 2020) is central to our thinking and ubiquitously manifested in our language. Given its importance, the teaching of conceptual metaphors has gained much attention in Cognitive Linguistics and Applied Linguistics. While most empirical studies have focused on specific aspects…

This dissertation uses the Conceptual Blending Hypothesis from the socio-cognitive method presented and refined by Kecskes (2002, 2004, 2007, 2010, 2020) to explain how the lexical choice of bilinguals differs across sociocultural situations. Quantitative (lexical density, lexical diversity, and lexical sophistication) and qualitative (lexical…

This dissertation explored whether unnecessary linguistic complexity (LC) in mathematics and biology assessment items changes the direction and significance of differential item functioning (DIF) between subgroups emergent bilinguals (EBs) and English proficient students (EPs). Due to inconsistencies in measuring LC in items, Study One adapted a…

Second language (L2) writing has been determined to be influenced by what is read, with language learners tending to borrow words and short phrases from input texts while writing (e.g., Wang & Wang, 2015). This phenomenon is referred to as lexical alignment. Only one empirical study has investigated the influence that the linguistic complexity…

While recent research has shown that multimodal feedback and use of formulaic sequences (FS) are effective in improving student performance on writing tasks, there is a dearth of studies on the impact of these aspects on computer-based academic speaking assessments. This dissertation seeks to fill this gap by examining the impact of both…

This dissertation examines the interface between music and language in "Huju", which is a Shanghai dialect based regional opera. Chapter I is a short introduction. Chapter II presents a thorough review of the studies on linguistic tone and music tune, and provides descriptive background information about "Huju" and Shanghai…

One of the most researched challenges in learning Spanish is the acquisition and use of the past aspect, namely, the preterit and imperfect. L2 learners encounter this challenge due to differences in how native English and Spanish speakers view past events. Numerous studies on the Spanish past aspect have analyzed L2 learners' past aspectual…

Studies in English as a Foreign Language (EFL) indicate that the use of discourse markers (DMs) in the academic writing of second language learners improves the overall quality of these texts by contributing to their cohesion and comprehensibility (Saif Modhish 2012; Jalilifar 2008; Intaraprawat & Steffensen 1995). However, despite the…
