Strategic competence, or the cognitive resources necessary for utilizing language knowledge, is widely recognized as an essential component of second language (L2) ability. However, research on strategic competence in the context of L2 speaking assessment has been limited, and findings have been inconsistent, making it challenging to discern the…

The demographic changes in the U.S. have contributed to linguistic, cultural, and ethnic diversification of today's society; however, monolingual ideologies continue to define many societal and academic discourses due to their historical roots (Matsuda, 2006; Wiley, 2014). One area of higher education that this trend is observed is academic…

As online collaboration continues to normalize in the post-pandemic digital age, how students engage online through collaborative learning has grown in importance. Web 2.0 has led to a shift in learner engagement that impacts the ways students interact with class content, and this provides opportunities for more meaningful collaboration and…

This study was focused on adult English language learners (ELLs) that described their experiences with language acquisition in an elementary, middle, or high school in the United States. The problem addressed in this qualitative descriptive study was that public schools were unable to handle the academic inadequacies of ELLs as well as the…

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…

Multilingual college students often struggle with writing and revising for academic purposes. This dissertation explored the effectiveness of a Concept-Based Language Instruction (C-BLI) approach to teaching revision processes to college-level multilingual writers. Although a significant body of research exists on effective feedback on…

Academic vocabulary is one of the most important skills needed in language learning, but it may be difficult for students whose native language is not English. The purpose of this qualitative study is to investigate how classroom core subject teachers at Middle School 55 (pseudonym) perceive their ability to implement specific instructional model…

Speech disfluencies refer to interruptions in the forward flow of speech and are distinct from the colloquial use of "fluency," to characterize knowledge of a language. Prior research indicates that some speech…

Given the increasing number of multilingual learners enrolled in U.S. secondary schools and persistent disparities in access to quality STEM education for these students, teacher education programs must prepare secondary science teachers capable of teaching multilingual learners in equitable ways. There is a consensus in science education…

Although studies in higher education have paid attention to the complexities of learning disciplinary language and discourse, little attention has been given to learning professional discourse in a second language (L2). Recent studies on language socialization have addressed this gap by focusing on L2 students' emerging communicative competence in…

This doctoral dissertation explores diverse facets of online research and comprehension among college students with English as a second or foreign language (L2 students). The research involves three distinct investigations within this overarching theme. Firstly, the study delves into the online reading and writing practices employed by Korean L2…

Bilingual education in the United States basically involves English language learners (ELLs) in mainstream classes and students who are learning an additional language in a foreign language immersion (FLI) program. Although academic vocabulary instruction for ELLs has attracted increasing attention in the past two decades (e.g., McQuillan, 2019;…

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…

In the field of Instructed Second Language Acquisition (ISLA), written corrective feedback (WCF) has been shown to play a facilitative role in improving written accuracy (e.g., Ashwell, 2000; Ferris & Roberts, 2001; Ferris, 2006; Sheen, 2007; Bitchener, 2008; Liu & Brown, 2015). However, studies that examine the effects of different types…
