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…

Despite the increasing popularity of dual language education programs in Taiwan, limited research assesses their effectiveness. This study evaluated eight English Immersion Programs (EIPs) in Taiwan, representing a dual language education model, using the "Guiding Principles for Dual Language Education" (GPDLE) framework. Interviews with…

This study investigated the effects of Native English-Speaking Teachers (NEST) and Non-Native English-Speaking Teachers (NNEST) on students' English proficiency and perceptions. The research methodology employed an observational study based using critical applied linguistic. Data collection was through a mixed method. The tools used were the…

In the current study, two experiments were carried out: the first tested the development of derivational root and word-pattern morphological awareness in Arabic; the second tested morphological processing in Arabic spelling. 143 Arabic native speaking children with normal reading skills in 2nd, 4th and 6th grade participated in the study. The…

The parallels between reading and spelling skills in Arabic were tested. One-hundred forty-three native Arab students, with typical reading development, from second, fourth, and sixth grades were tested with reading, spelling and orthographic decision tasks. The results indicated a full parallel between the reading and spelling performances within…

The task of writing arguments requires a linguistic and cognitive sophistication that eludes many adults, but students in the US are expected to produce texts that articulate and support a claim--simple written arguments--starting in the fourth grade. Students from language-minority homes likewise must learn to produce such writing, despite their…

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…

The current study examines the effects of digital scaffolding on the English literacy of fourth- and sixth-grade students. A total of 1085 native English-speaking and language minority students from 25 treatment classes and 20 control classes across three school districts participated in this study for one school year. Treatment students read…

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 case study examines the implementation of "Foreign Language Activities" (English language education), which officially began in Japanese elementary schools in 2011. Subjects in this study included 37 Japanese classroom teachers (20 males and 17 females) in four elementary schools in Tokyo. The Teacher Foreign Language Anxiety Scale…

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…

One dimension of language proficiency considered important for reading and writing academic texts is morphological awareness--the understanding of how complex words are formed from meaningful smaller units (i.e., affixes, roots) that contribute to words' meanings and functions. This quasi-experimental study evaluated the effects of instruction on…
