Our research team performed an exploratory analysis of teacher gesturing via a case study of an elementary teacher. We focused on gesturing, a practice found to support both bilingual English learner students' linguistic development and mathematics achievement, during the teacher's engineering and science lessons. The research team systematically…

This guidance is designed as a companion resource to the Office of Superintendent of Public Instruction's (OSPI's) "Reopening Washington Schools 2020: District Planning Guide" (ED606044), issued June 2020. The goal of this companion document is to provide guidance, best practices, resources, and unique considerations for supporting…

We investigated how bilinguals choose words in a narrative task, contrasting the possibilities of a developmental delay vs. compensatory strategies. To characterize a developmental delay, we compared younger (three to five years) and older (seven to ten years) children's lexicalization of target words (Study 1). The younger children told shorter…

Educators frequently report feeling constrained by the competing and often conflicting demands of their curriculum, students, assessment requirements, supervisors, and parents. They fear, with all the mandates and pressures, they are unable to be the kind of personalized learning leader they want to be. The goal of this guide is to encourage…

Two-way immersion (TWI) programs in the U.S. integrate learners with different home languages and varied proficiencies in Spanish and English. Although both English home language (EHL) and Spanish home language (SHL) TWI students succeed academically in English, they often experience incomplete acquisition (Montrul 2011. "Morphological Errors…

This brief shares findings from a formative evaluation of Early Childhood Language Development Institute (ECLDI) programs at two early learning sites. At each, ECLDI provided training and support to program leadership, teaching teams, and families. The brief provides a summary of the report and discusses lessons for the field. [This three-part…

Dual language learners make up an increasing share of preschool students, but they often perform worse than monolingual students on assessments measuring school achievement. This study compares Head Start classrooms implementing either the dual language model or the English with home language support model. The author examines how the models…

The aim of this ethnographic study was to trace the English language development of a young boy from Syria (Nate, pseudonym) who relocated to the U.S. at the age of six without any prior exposure to formal schooling. Data were collected over a two-and-a-half-year period and included fieldnotes after weekly tutoring visits and writing samples. Nate…

Early childhood education and care (ECEC) programs across the United States are experiencing an increasing level of linguistic and cultural diversity among the children they serve. Dual Language Learners (DLLs)--young children who grow up speaking more than one language at home and in the classroom--bring to these classrooms unique learning…

Purpose: This study evaluated a newly developed quasi-universal nonword repetition task (Q-U NWRT) as a diagnostic tool for bilingual children with language impairment (LI) who have Dutch as a 2nd language. The Q-U NWRT was designed to be minimally influenced by knowledge of 1 specific language in contrast to a language-specific NWRT with which it…

Purpose: Current understanding about the effect of first language (L1) background on morphological awareness (MA) development in those who are bilingual is largely limited to school-aged second-language learners. This study examined the development of MA in bilingual Mandarin-English (ManEngBi) and Spanish-English (SpaEngBi) children ages 4 to 7…

In the field of third language acquisition metalinguistic awareness is posited to be a fundamental component of multilingual competence and a key factor facilitating the acquisition of additional languages. Building upon Bialystok's model of attention and control, and Wrembel's research into metaphonological awareness in adult L3 learners, this…

More than 7.4 million U.S. children ages 5 and under live in a household where a language other than English is spoken by a parent or caregiver. But despite the size and growth of this Dual Language Learner (DLL) population, and these children's distinct linguistic assets and learning needs, standardized policies for identifying them and…

It is estimated by the year 2030, over 40% of the K-12 population in U.S. schools will be children whose first language is not English (Shin & Ortman, 2011; U.S. Census Bureau, 2007;). This shift has negative academic consequences for emergent bilingual students (EBS). Schools (K-12) unable to meet the needs of EBS contribute to these…

This study evaluated the Science and Literacy Instructional Model aimed at helping primarily Hispanic bilingual/English Learners (ELs) and economically disadvantaged fifth grade students with science achievement as measured by high-stakes standardized science achievement scores. The model combined purposeful planning, innovative academic…
