Since the earliest studies on multilingual advantages, it has proved difficult to disentangle language development from general cognition. It remains unclear whether language interdependence is an independent variable or whether observable effects are mediated by cognitive ability. Measurable effects of one language on another typically go hand in…

This study explores the reading strategies (RSs) of bilingual and monolingual young learners in their first and second languages (L1 and L2, respectively)--either Kazakh or Russian as the L1 and L2--and English as a foreign language (L3). It also examines the influence of RSs on the learners' performance on reading comprehension tests in the three…

This brief explores the potential of bilingual programs to support access to core content courses for students classified as English Learners (ELs). The most common types of bilingual education programs in Oregon are: (1) dual language: instruction is in English and a partner language, with goals of biliteracy and bilingualism.

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…
