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'…

The Office of English Language Acquisition (OELA) has synthesized key data on English learners (ELs) into two-page sheets on a variety of subjects. The topics for this report on English learners and science achievement include: (1) National Assessment of Education Progress Science Score Comparison for English Learners and Students Who Are Not…

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 National Assessment of Educational Progress (NAEP), also known as the Nation's Report Card, is the largest continuing and nationally representative assessment of what students know about mathematics, reading, science, writing, the arts, civics, economics, geography, U.S. history, and technology and engineering literacy. This fact sheet reports…

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…

Using data from seven cohorts of language immersion lottery applicants in a large, urban school district, we estimate the causal effects of immersion programs on students' test scores in reading, mathematics, and science and on English learners' (EL) reclassification. We estimate positive intent-to-treat (ITT) effects on reading performance 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…

Language immersion students' lexical, syntactic, and pragmatic competencies are well documented, yet their phonological skill has remained relatively unexplored. This study investigates the Spanish vowel productions of a cross-sectional sample of 35 one-way Spanish immersion students. Learner productions were analyzed acoustically and 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…

Using longitudinal data on a nationally representative U.S. cohort, this study examined the roles of language minority (LM) status and English proficiency in English reading growth across the elementary and middle school years. Piecewise growth modeling was used to compare English reading growth trajectories for native English speakers and LM…

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…
