The rising demand for dual-language immersion (DLI) programs, which offer core instruction in two languages from early grades onward, has raised questions about program design and access. We leverage the rapid expansion of DLI schools across the U.S. state of Utah to estimate effects of DLI program availability on the academic achievement of…

Purpose: There is limited research on the writing of young Spanish-English bilinguals and their writing in both languages. In the current study, we addressed whether written syntax features differed by language (English and Spanish) and varied as a function of grade level, English learner status, and instructional program (dual or English…

We investigated spelling errors in English and Spanish essays by Spanish-English dual language learners in Grades 1, 2, and 3 (N = 278; 51% female) enrolled in either English immersion or English-Spanish dual immersion programs. We examined what types of spelling errors students made, whether they made spelling errors that could be due to…

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…

We describe research results and lessons learned from a laboratory/ classroom collaboration with a school system offering both traditional English-only education and a dual-language track (Spanish/English). Through this collaboration, we addressed basic research questions informing malleable factors that impact cognitive development. In a…

English learners (ELs), students from a home where a language other than English is spoken and who are in the process of developing English proficiency themselves, represent over 10% of the US student population. Oftentimes education policies and practices create barriers for ELs to achieve access and outcomes that are equitable to those of their…

Schools are under increasing pressure to reclassify their English learner (EL) students to "fluent English proficient" status as quickly as possible. This article examines timing to reclassification among Latino ELs in four distinct linguistic instructional environments: English immersion, transitional bilingual, maintenance bilingual,…

Many educators and policymakers look to two-way dual language immersion as one of the most promising options to close achievement gaps for English learners. However, the programs' effectiveness depends on the quality of their implementation. This article reports on a large-scale study of the implementation of dual language immersion across a…

Research has demonstrated that students in dual-language immersion programs perform as well as, or better than, their peers in core academic content areas by late elementary school. The extent to which immersion education fosters bilingualism, however, has received less attention in the literature. Using data from a four-year efficacy study of…

This paper investigates the differences in academic achievement trajectories from elementary through middle school among English Learner students in four different instructional programs: English Immersion, Transitional Bilingual, Developmental Bilingual, and Dual Immersion programs.
