Description: This is a systematic review of randomized controlled trials, quasi-experimental controlled studies, and regression discontinuity designs pertaining to the effect of Spanish versus English literacy instruction on English literacy development in native Spanish speakers learning English as a second language.
Does literacy instruction in Spanish promote or interfere with Spanish-speaking English language learners’ literacy development in English?
Population: Native Spanish speakers who were learning English as a second language and who were enrolled in preschool through fifth grade
Intervention/Assessment: Literacy instruction in Spanish versus English
Number of Studies Included: 5
Years Included: 1990 - 2007
The results of these studies indicate that Spanish literacy instruction does not interfere with English language learning. Furthermore, literacy instruction in both Spanish and English was shown to improve English literacy skills more than instruction in English alone.
