Longitudinal Predictors of Bilingual Language Proficiency, Decoding, and Oral Reading Fluency on Reading Comprehension in Spanish and in English

Abstract

This study examined the longitudinal prediction of decoding, oral reading fluency (ORF), and bilingual language proficiency (BLP) on student reading comprehension (RC) outcomes in Spanish and in English. Participants were first-grade Latinx students attending bilingual programs. Findings indicated that BLP initial status and gains were significant predictors of Spanish and English RC at the end of second grade. English and Spanish decoding in first grade, in addition to BLP, explained 27 percent of the variance in English reading comprehension. However, only Spanish decoding was a significant predictor of Spanish reading comprehension. Once English and Spanish second grade ORF scores were added to the model, decoding no longer explained any of the variance in RC. BLP, English ORF initial status and gains, and Spanish gains explained 47 percent of the variance in English reading comprehension. BLP and Spanish ORF initial status explained 46 percent of the variance in Spanish RC. IMPACT STATEMENT The findings from this study provide school psychologists and teachers relevant information on the importance of measuring bilingual student decoding and oral reading fluency in Spanish and in English as well as bilingual language proficiency to ensure students are comprehending what they read in both languages. There are differences between the predictive utility of these variables on Spanish and English reading comprehension that should be considered when making instructional decisions for bilingual students. For researchers, more measures are needed that can assess student bilingual language proficiency briefly, efficiently, and reliably, as well as additional studies examining how bilingualism can benefit and enrich bilingual student reading comprehension.
