In the ever-changing digital era, the surge of online informal language learning platforms has revolutionized the way we learn new languages. This dissertation delves into the critical role of interactional feedback (IF) in synchronous computer-mediated communication (SCMC), a cornerstone for optimizing these digital learning spaces. Anchored in…

The purpose of these two studies was to examine the state of pre-service and in-service literacy training, self-efficacy, and clinical practice of speech-language pathologists (SLPs) and speech-language pathology programs in the United States. Study one analyzed course descriptions and available syllabi from a sample of 50 accredited graduate…

This dissertation provides an in-depth linguistic description and analysis of the discourse in a target domain of digital games, a domain referred to as "single player offline role-playing games." Gaming discourse from this domain is represented by a 4.8-million-word corpus of spoken and written language extracted from the digital files…

In this research study, an instructional intervention protocol is described. This intervention was designed to help teachers to engage English Learner students (ELs) in mathematical problem-solving lessons and reasoning through discourse. The "Discursive Mathematics Protocol" (DMP) integrates Polya's classic problem-solving framework and…

In the Chittagong Hill Tracts (CHT) (Appendix A), a remote region in the south-eastern corner of Bangladesh, children from indigenous mountain tribes are among the country's most illiterate and at the highest risk of dropping out of school (UNDP, 2009). Their school achievement and completion rate fall disastrously short when compared to the…

Purpose: The purpose of this quantitative, causal-comparative study was to determine whether English learners who participated in transitional kindergarten perform equally or better than English learners who did not participate in transitional kindergarten in the areas of oral language, written language, and overall language as measured by the…

The problem addressed in this quantitative experimental study was that students were having more difficulty learning from audiovisual lessons than necessary because educators had eliminated textual references, based on early findings from CLT research. In more recent studies, CLT researchers estimated that long-term memory schemas may be used by…

This study fills the existing gap in the research, which indicates that few researchers have examined multilingual writers' preference between audio and written feedback, and the impact of feedback format on their revision process. However, this dissertation has five interrelated purposes: 1. To understand the expectations of multilingual writers…

This dissertation study aims to theorize an instructional practice which I labeled languaging thinking. Languaging thinking is conceptualized as a social practice in which teachers and students make visible and discuss how to think about a particular task, topic, or activity, through the use of spoken and written language and related semiotic…

The achievement gap between African American students and their Caucasian peers is a problem that has persisted within the educational system since the early 1970s. Researchers have been investigating whether differences in oral language, such as, Nonmainstream American English (NMAE) use contribute to this gap. There is also concern from…

Adolescent newcomer students bring a wealth of linguistic and cultural resources to their learning environments--resources that become even more dynamic when combined with those of their peers. While a significant body of research has explored students' deployment of multilingual resources through translanguaging, most of this work does not…

As China increasingly internationalizes its higher education system, growing numbers of Chinese learners and expatriate instructors meet in the classroom, engaging one another from their disparate cultural and pedagogical standpoints. Despite its widespread occurrence, the phenomenon of Chinese learners and Western instructors engaging one another…

The triad dimensions of complexity, accuracy, and fluency (CAF) has been widely used for assessing second language performance and development. Unlike accuracy and fluency, the construct of Chinese syntactic complexity has not been comprehensibly conceptualized or operationalized. Moreover, not tailored to the typological differences such as the…

This mixed-methods study examined the lived experience of adult English Language Learners (ELLs) in classrooms led by native speaking teachers, compared with their experience in classrooms led by non-native teachers. The socio-cognitive approach to language and emergent common ground framed the development of the English classroom as a Community…

This dissertation uncovered how a group of second language (L2) students, including international and immigrant students, became socialized into American academic discourse through the writing that they did as graduate students in the context of their academic field. In particular, this study focused on Mandarin Chinese-speaking graduate students…
