This is a qualitative case study framed by a sociosemiotic theoretical framework to explore science and language instruction with three Emergent Bilinguals (EBs) in sixth grade. The study details the modeling and explanatory processes used by EBs to mediate science learning through evidence-based argumentation. A thematic analysis of students'…

Using U.S. state-level data, we report unadjusted and adjusted odds ratio of special education (SPED) trends in Tennessee from 2009 to 2019 for students in Grades 3 to 8 by three language groups: native English speakers (NES), English-proficient bilinguals (EPB), and Current English learners (Current EL). We report trends across all SPED…

Using state-level data, we report unadjusted and adjusted odds ratio of special education (SPED) trends in Tennessee from 2009-2019 for students in grades 3-8 by 3 language groups: native English speakers (NES), English-proficient bilinguals (EPB) and Current English learners (Current EL). We report trends across all SPED disability categories and…

The central aim of this study was to clarify whether sign language (SL) nativeness is a significant factor in determining prelingually deaf individuals' reading skills and whether its contribution is modified by the reader's orthographic background. A second aim was to elucidate similarities and differences between native and nonnative signers in…

All native speakers of Arabic read in a language variety that is remarkably distant from the one they use in everyday speech. The study tested the impact of this distance on reading accuracy and fluency by comparing reading of Standard Arabic (StA) words, used in StA only, versus Spoken Arabic (SpA) words, used in SpA too, among Arabic native…

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…

This paper reports the results of a descriptive study on the use of a technology-enhanced formative assessment system called Accelerated Math (AM) for ELLs and their native-English-speaking (NES) peers. It was comprised of analyses of an extant database of 18,549 students, including 2,057 ELLs, from grades 1 through 8 across 30 U.S. states. These…
