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…

We examined the contributions of English proficiency, genre, and the use of textual sources to adolescent writing. The sample included 1819 native English speakers and language minority students from 127 seventh- and eighth-grade classes in an urban school district. Students were randomly assigned one of three source-based essay prompts…

Vocabulary is a building block of understanding, especially in science classrooms where language abilities are mixed. To reduce academic inequalities, approaches to vocabulary instruction need to demonstrate benefits for students across learning contexts. We summarize the results from the first unit, "Earth Systems and Catastrophic…

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…

This article examines the language proficiency and achievement outcomes of Latino students enrolled in a dual language programme who varied by language proficiency (Native English speakers, Current English Language Learners--ELLs, Fluent English Proficient/Previous ELLs). Most previous research has not disaggregated Latino students, especially…

Current assessment practices in the United States are not able to accurately capture the total linguistic, cognitive, and achievement abilities of bilingual learners. There are psychometric complexities involved when assessing and interpreting test results of bilingual students, which impact the validity of this practice. Further, the compromise…

The development of English language learners (ELLs) was explored from kindergarten through eighth grade within a nationally representative sample of first-time kindergartners (N = 19,890). Growth curve analyses indicated that, compared to native English speakers, ELLs were rated by teachers more favorably on approaches to learning, self-control,…
