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…

With this article I explore the relationship between core academic language skills (CALS) -- a construct representing a set of high-utility language skills needed to manage the linguistic features prevalent in academic texts across content areas -- and schooling outcomes. There has long been an understanding that there is a distinction between…

This dissertation focused on comparing the academic achievement and language proficiency in both English and Spanish of students at risk for language and learning difficulties, with bilingual typically developing students in two bilingual educational contexts: English as a Second Language program and Spanish two-way immersion program. Data was…

This mixed-method study explored the culturally responsive practices of a midsized, Southern California school district that used Expanded Learning Opportunities Program (ELOP) state funding to implement a voluntary summer program accessible to TK--6 grade students district-wide. Qualitative data gathered from semistructured interviews with the…

The Office of English Language Acquisition (OELA) has synthesized key data on English learners (ELs) into two-page sheets on a variety of subjects. This fact sheet provides the following data on ELs in the United States over the 2017-2018 school year: (1) Percentage of Students Enrolled in K-12 Who Are English Learners; (2) English Language…

Two major reforms have transformed California's K-12 education system over the past decade. To revamp English and mathematics instruction, the Common Core standards were adopted in 2010, with district implementation beginning several years later. In 2013, the Local Control Funding Formula (LCFF) was enacted to increase funding for disadvantaged…

During the academic year in the state of Georgia, EL students in public schools take the Georgia Milestones End-of-Grade and the ACCESS 2.0 assessments, which are in line with the state-mandated subject area standards in mathematics, science, language arts, and social studies, as well as English language proficiency standards (Georgia Department…

Substantial progress has been made toward applying technology enhanced conversation-based assessments (CBAs) to measure the English-language proficiency of English learners (ELs). CBAs are conversation-based systems that use conversations among computer-animated agents and a test taker. We expanded the design and capability of prior…

The study focuses on the assessment of young refugee students, and the role of language and parents therein. Low achievement at tests can stem from lack of knowledge of the content being tested. However, it can also be due to low proficiency in the language of testing. Additionally, poor communication between refugee parents and schools caused by…

In this study we investigated how English learners (ELs) interacted with "®" summative English language arts (ELA) and mathematics items, the embedded online tools, and accessibility features. We focused on how EL students navigated the assessment items; how they selected or constructed their responses; how they interacted with the…

We examined whether English language proficiency (ELP) related to interim reading and math performance differently when academic assessments were administered to students in either English or Spanish. We also tested these effects with Spanish language proficiency (SLP) as well as jointly with ELP and SLP. Students from a midwestern suburban school…

This Study Snapshot highlights key findings from a study that examines full-day kindergarten (FDK) implementation in Oregon. The evidence base on FDK is generally positive for short-term effects and unclear for longer-term effects, with some prior research associating FDK with gains in student outcomes such as grade 3 math and reading standardized…

English learners' (ELs) day-to-day experiences in school change when reclassified as fully English proficient. Prior research, however, is mixed on how reclassification influences outcomes. Many studies also do not or cannot explore key long-term outcomes or identify impacts over time. In this study I leverage longitudinal student data in a…

English Learners (ELs) enrollment in the U.S. public schools continues to increase. ELs have various linguistic needs including listening, reading, speaking, and writing English. Often this group of students does not perform well academically on state assessments since these assessments are normally written in English and require substantial…

New Mexico's Every Student Succeeds Act state plan set the goal for all English learner students to attain English proficiency within five years. The Regional Educational Laboratory Southwest English Learners Research Partnership conducted this study to better understand progress toward English proficiency among American Indian English learner…
