The population of English learners (ELs) in K-12 schools continues to grow. Between the 2009-10 and 2014-15 school years, the percentage of English learners increased in over half of the states, and in 2017, English learners made up 10.1% of the total student population. Research suggests that in their transition to English, non-native speakers…

Using local linear matching, we find that…

The United States is becoming a more culturally and linguistically diverse nation. This is especially true when we look at the youngest generation of learners. This growing diversity increases the need to accurately identify young children as dual language learners (DLLs) prior to kindergarten. Ensuring educators have a strong understanding of…

In 2006, Arizona ELL Task Force implemented Structured English Immersion (SEI) within its public schools to educate emergent bilingual (EB) students. Although prior research has demonstrated limitations of SEI, we investigate whether institutionalization has improved its implementation and outcomes using coordinators' and teachers' responses from…
