The purpose of the present study is to investigate similarities and differences in the listening behaviors of native speakers and learners of Japanese, focusing on the production of "aizuchi" and head nods. The term "aizuchi" is often interchangeably used with the word backchannel, and these are characterized as the…

Understanding the sources of variance in speaking assessment is important in Japan where society's high demand for English speaking skills is growing. Three challenges threaten fair assessment of speaking. First, in Japanese university speaking courses, teachers are typically the only raters, but teachers' knowledge of their students may unfairly…

Although much research has gone into the sociolinguistics of the linguistic landscape (space for and language of public signs) in the "peripheral," non-native contexts of English Language use and users, none has been specifically devoted to a Nigerian context. This dissertation is intended to fill this wide gap. Focusing on the Ibadan…

The general goal of this dissertation is to explore two decades-long second language (L2) acquisition issues: whether and to what extent the L2 learner's first language (L1) and Universal Grammar (UG) respectively play a role in L2 development. Targeting English verb phrase ellipsis (VPE) and "wh"-extraction out of VPE, four…

This study compares native English, Spanish, Lao, Chinese, Korean, Vietnamese, Arabic, and all other ELL students over one, two, three, and four-year spans to determine if certain groups appear to face more difficulties in developing early reading mastery by third grade. This study also examines whether socio-economic status impacts the…

When factorial invariance is established across translated forms of an instrument, the meaning of the construct crosses language/cultures. If factorial invariance is not established, score discrepancies may represent true language group differences or faulty translation. This study seeks to disentangle this by determining whether…

This mixed methods study investigates how Japanese non-native English speaking teachers' (NNESTs) efficacy and identity are developed and differentiated from those of native English speaking teachers (NESTs). To explore NNESTs' efficacy, this study focuses on the contributing factors, such as student engagement, classroom management, instructional…

This study gathered information on student engagement with Facebook, and described non-native English speakers' (NNS) expectations and experience. This also assessed the relationship this technology has with writing efficacy and compared NNS and native English speakers (NS) groups. Demographic data were collected and means were compared to…

This dissertation investigates and problematizes emergent bilingual students' achievement gaps in an existing corpus of middle-school science assessment data. I first characterize achievement gaps across national data, state data, and the corpus of approximately 27,000 students as an analytic backdrop. I then sample a subset of the 6th grade…

As an initial step toward understanding which features of academic language make science-based expository text difficult for students with different English language proficiency (ELP) designations, this study investigated fifth-grade students' thoughts on text difficulty, their knowledge of the features of academic language, and the…

This study investigates the dynamics in the Spanish classroom between heritage language learner (HLL) dyads, second language learner (L2L) dyads, and mixed HLL-L2L dyads. Specifically, it examines oral, written and embodied discourse that informs our understanding of how learners attend to language. Analysis for this dissertation examined…

Substantial changes to the undergraduate population at US universities have created a need for the development of a model of academic literacy and a corresponding means of measuring academic readiness that addresses contextualized, communicative English language competence. This paper presents a unified model of academic literacy which treats…

The German /r/ sound is one of the most difficult sounds for American English (AE) speakers who are learning German as a foreign language to produce. The standard German /r/ variant [/R/] and dialectal variant [R] are achieved by varying the tongue constriction degree, while keeping the place of articulation constant [Schiller and Mooshammer…

While normal child language acquisition results in complete productive and comprehension abilities at a relatively young age, adult language acquisition is more belabored and often results in linguistic abilities that differ from those of native speakers in terms of both productive and comprehension abilities. A major line of research in language…

This study examines proposals made during planning talk--a speech act that has received little attention in previous literature--to determine the applicability of the stages of second language (L2) pragmatic development posited by Kasper and Rose (2002). Although Kasper and Rose suggest that formulas play a prominent role in L2 pragmatic…
