This study assessed the extent to which executive functions (EF), according to their factor structure in 5-year-olds (N = 244), influenced early quantity-number competencies, arithmetic fluency, and mathematics school achievement throughout first and second grades. A confirmatory factor analysis resulted in updating as a first, and inhibition and…

This study investigated contributors of English reading comprehension outcomes among predominantly U.S.-born 1st- and 3rd-grade (N = 73) dual language learners (DLLs) from Spanish-speaking, low-income homes who attend English-only instructional schools in the Southern region of the United States, which is experiencing historic rates of school-age…

We discuss a component-based, developmental view of text writing fluency, which we tested using data from children in Grades 2 and 3. "Text writing fluency" was defined as efficiency and automaticity in writing connected texts, which acts as a mediator between text generation (oral language), transcription skills, and writing quality. We…

This study examined the roles of first-language (L1) Chinese and second-language (L2) English phonological skills in English and Chinese reading comprehension, respectively, and their association with reading comprehension difficulties among Hong Kong Chinese-English bilingual children. We tested 258 second graders on nonverbal intelligence,…

We examined the role of executive attention, which encompasses the common aspects of executive function and executive working memory, in children's acquisition of two aspects of mathematical skill: (a) knowledge of the number system (e.g., place value) and of arithmetic procedures (e.g., multi-digit addition) and (b) arithmetic fluency (i.e.,…

This study investigated the adequacy of an expanded simple view of reading (SVR) framework for English language learners (ELLs), using mediation modeling approach. The proposed expanded SVR included reading fluency as an outcome and phonological awareness and naming speed as predictors. To test the fit of the proposed mediation model, longitudinal…

We empirically examined the effect of reading comprehension on passage fluency in English and Spanish in the context of Cummins interdependence hypothesis (1979) and Perfetti's blueprint of the General Components of Reading (1999). Participants were 96 second-grade English learners being taught to read in Spanish and English. Measures in both…

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…

Mathematical learning disabilities (MLDs) are often associated with math anxiety, yet until now, very little is known about the causal relations between calculation ability and math anxiety during early primary school years. The main aim of this study was to longitudinally investigate the relationship between calculation ability, self-reported…
