Recent research suggests that using additional teachers to provide small-group instruction or tutoring substantially improves student learning. However, treatment effects on test scores can fade over time, and less is known about the lasting effects of such interventions. We leverage data from a Norwegian large-scale field experiment to examine…

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…

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…

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…

Language immersion education uses a non-English language for a significant portion of instruction. One goal is to develop bilingual students, which many argue provides cognitive benefits. Using data from school choice lotteries, I estimate the effect of random assignment to a language immersion school on achievement in math and reading. Winning…

The purpose of this study was threefold: to examine unique and shared risk factors of comorbidity for reading comprehension and word-problem solving difficulties, to explore whether language minority (LM) learners are at increased risk of what we refer to as "higher order comorbidity" (reading comprehension and word-problem solving…

The PM Benchmark Reading Assessment Resource (PM Benchmarks) provides information about primary students' level of achievement in reading accurately, fluently, and in understanding unseen texts. As part of the assessment, students have to orally retell what they have read and orally answer comprehension questions. This oral use of language…

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…

This study assesses the long-term linguistic and academic outcomes associated with different bilingual language education models for low-income dual language learners (DLLs) residing in a bilingual, bicultural context. As part of the Miami School Readiness Project (MSRP), we analyzed the impact of program model on gains in English language…

The purpose of this quantitative study was to examine the relationship of language proficiency (WIDA) on the performance of third, fourth, and fifth grade English language learners who were administered the Virginia Standards of Learning (SOL) assessments during the 2017-2018 assessment year.

Students' performance is summarized by program.

The purpose of this study was to investigate the impact of teaching daily math word problems in a 3-6th grade ELL classroom on math vocabulary use and math word problem and place value comprehension. This study sought to answer the following research question: "How does direct instruction of mathematical operation keywords through teaching…

This paper shows how an American International School in Vietnam has been using data and Learning Analytics to find out about students' learning from their assessments and how they use these findings to improve, among other areas, the reading skills of their mostly English as an Additional Language (EAL) student population. The source of data…
