Are First- and Second-Language Factors Related in Predicting Second-Language Reading Comprehension? A Study of Spanish-Speaking Children Acquiring English as a Second Language From First to Second Grade

First-language (L1) and 2nd-language (L2) oral language skills and L2 word reading were used as predictors to test the simple view of reading as a model of 2nd-language reading comprehension. The simple view of reading states that reading comprehension is related to decoding and oral language comprehension skills. One hundred thirty-one Spanish-speaking English learners (ELs) were tested in 1st grade and many were followed into 2nd grade, including a full sample of 79. Structural equation modeling confirmed that a 5-factor measurement model had the best fit, suggesting that L1 and L2 phonological awareness should be viewed as separate but related constructs and that L1 and L2 oral language proficiency, measured by vocabulary and grammatical awareness, were separate constructs. The structural model indicated that for this group of ELs, who were educated in English, English oral language proficiency and word reading were the strongest predictors of English reading comprehension. Other models that deleted I of these crucial components resulted in significantly poorer fit. Therefore, the results support the validity of the simple view of reading as a model for the development of reading comprehension in young ELs. Implications for theory and practice, specifically assessment of ELs, are discussed.
