The objective for beginning writers is to learn how to generate alphabet-letters which are recognisable and easy to read. This study investigated the accuracy of Year 1 and 2 children's alphabet-letter-writing by evaluating their alphabet and orthographic knowledge, following evidence which identifies these skills as important for correctly…

The phonological loop of the working memory system plays a key role in language learning. This study examined the trajectories between two dual-language learner groups (English Learners [ELs] and Spanish Learners [SLs]) on phonological loop measures in L1 and L2. At Grade 1, children completed a battery of vocabulary and cognitive measures and…

We investigated the extent to which working memory and behavioral attention predicted reading and listening comprehension in grades 1 through 3 and, whether their relative contributions differed by modality and grade. Separate grade samples (N = 370; ns = 125, 123, and 122 for grades 1, 2, and 3 respectively) completed multiple measures of word…

The outcomes of a longitudinal randomized number sense intervention including pre-, post- and follow-up tests are reported. The intervention was conducted in Grade 0 when children were six years old. Using Concrete-Representational-Abstract principles, a structured explicit 10-week program focusing on numbers and collective reasoning about…

The purpose of this longitudinal study was to examine whether young learners of varying reading and spelling performance, identified in Grade 2, can be distinguished retrospectively from kindergarten, based on their growth profiles in cognitive (planning, attention, working memory--WM) and linguistic (phonological--PA and naming speed--RAN)…

Developmental dyscalculia (DD) is a specific learning disability in mathematics that affects around 6% of the population. Currently, the core deficit of DD remains unknown. While the number sense deficit hypothesis suggests that the core deficit of DD lies in the inability to represent nonsymbolic numerosity, the access deficit hypothesis suggests…

This article reports a study examining whether foreign language (FL) word learning can be improved with reduction in cognitive load. Cognitive load theory has received substantial supports in various fields of learning but never in FL word learning. Due to the defined poverty in exposure to the FL, hence deprived cognitive pre-requisites for…

Prior research on reading difficulties has mainly focused on word decoding problems. However, there exists another group of children -- poor comprehenders (PCs) -- who have normal word decoding abilities but difficulties in reading comprehension. Less is known about PCs especially in non-alphabetic languages such as Chinese. This study identified…

As the United States experiences greater income inequality, more and more students experience an early science achievement gap. This study tested several competing theoretical models of early science achievement with a longitudinal sample of 14,624 children who were followed from kindergarten entry to the end of 1st grade. To understand why and…

This study investigated the relationship among working memory, processing speed, math performance, and reactivity to stress in 83 Grade 1 children. Specifically, 39 children with math disability (MD) were compared to 44 children who are typically achieving (TA) in mathematics. It is the first study to use a physiological index of stress (salivary…

This study compared bilingual and monolingual school beginners on measures of simple and complex verbal working memory and receptive and expressive vocabulary. The aim was to determine whether the tests of working memory are fairer measures of language ability than the vocabulary tests for bilingual children when tested in their second language.…

The purpose of this study was to investigate the effects of 1st-grade number knowledge tutoring with contrasting forms of practice. Tutoring occurred 3 times per week for 16 weeks. In each 30-min session, the major emphasis (25 min) was number knowledge; the other 5 min provided practice in 1 of 2 forms. Nonspeeded practice reinforced relations…

Across multiple schools and sites, the impact of grade-at-intervention was evaluated for children at risk or meeting criteria for reading disabilities. A multiple-component reading intervention with demonstrated efficacy was offered to small groups of children in 1st, 2nd, or 3rd grade. In a quasi-experimental design, 172 children received the…

This longitudinal study investigated growth in reading-related skills between Grade 1 and 4 for language minority (LM) learners and their native English-speaking classmates from similarly low socioeconomic backgrounds (N = 166). Growth trajectories were compared by language background and by Grade 4 reading difficulties, with the goal of informing…

The authors examined an activity-based listening strategy with first- and third-grade children in mixed-grade dyads. On the basis of theories of cognitive development and previous research, the authors predicted the following: (a) children in an activity-based strategy would recall more story events compared with those in a repetition strategy and…
