This brief report summarizes the development and psychometric properties of German reading fluency passages as compared to English reading fluency passages for immersion language learners. Results indicated that scores from German language reading fluency passages alone were (a) somewhat less reliable than scores from English publisher-developed…

Nearly 20 percent of California school children are English Learners (ELs), and close to 40 percent of all transitional kindergarten through grade 12 (TK-12) students speak a language other than English at home. Federal law requires that these children receive supportive services so they can access academic content while becoming fluent in…

This brief provides findings from the full report, "Adapting to Changes in California's English Learner Population," which examines how the size and composition of the English Learner (EL) population has changed and whether services, program offerings, and learning trajectories have evolved in response to these changes. Key findings…

Research involving digital games and language learning is rapidly growing. One advantage of using digital games to support language learning is the ability to collect data on students learning in real time. In this study, we use educational data mining methods to explore the relationship between in-game data and elementary students' Chinese…

Prior research has shown that EL classification is consequential for students, however, less is known about how EL classification impacts students' outcomes. In this study, we examine one hypothesized mechanism: teacher perceptions. Using nationally-representative data (ECLS-K:2011), we use coarsened exact matching to estimate the effect of EL…

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…

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…

Two-Way Immersion (TWI) programs have demonstrated positive outcomes in students' academic achievement in English, yet less is known about content teaching and learning in the non-English language in these programs. This study uses math instruction as a lens to identify pedagogical strategies and challenges in the teaching of math in Korean to…

Across the United States, students who are deemed not to be proficient in English are classified as English learners (ELs). This classification entitles students to specialized services but may also result in stigmatization and barriers to educational opportunity. This article uses a regression discontinuity design to estimate the effect of EL…

This study examines the writing skills of students in grades 1 to 5 of an Italian-English two-way immersion program. Narrative writing samples were collected in both languages and scored for content, organization, grammar, mechanics, vocabulary, text length, and overall total score. The results show that writing skills improved as a function of…

The relationship between first language (L1) typology, defined as the classification of languages according to their structural characteristics (e.g. phonological systems and writing systems), and the development of second (L2) and third (L3) language skills and literacy proficiency in multilingual children was investigated in this study. The…
