This mixed-methods study explores the relationship between early elementary students' domain-specific vocabulary knowledge and their ability to comprehend grade-level reading passages on unfamiliar science topics. Specifically, this study used (a) structural equation modeling (SEM) to examine the extent to which students' networks of…

Visual-verbal paired-associate learning (PAL) is thought to be related to reading acquisition and, more specifically, to word reading skills. To date, the uniqueness and strength of this relationship has remained unclear because most studies have been conducted in opaque orthographies such as English, and few studies have controlled for all of the…

This study aims to classify subtypes of mathematics disability (MD) using a novel classification method, cognitive diagnostic models (CDMs), and examine whether domain-general skills, namely, linguistic, working memory, and spatial skills, were related to the identification of the subtypes. Participants were 454 children (246 boys; age: M ± SD =…

Theoretical models hold that written products (e.g., quality of written composition) are the outcome of the writing process (e.g., translation, transcription, revision) and skills and knowledge on which the writing process draws (e.g., language, transcription, cognitive skills). In the present study, we examined the relations among writing…

We examined longitudinal relations between 1st-grade cognitive predictors (early nonverbal reasoning, processing speed, listening comprehension, working memory, calculation skill, word-problem solving, word-reading fluency, attentive behavior, and numerical cognition) and 2nd-grade academic outcomes (calculations, word-problem solving, and word…

Within the context of the Direct and Indirect Effects Model of Writing (Kim & Park, 2019), we examined a dynamic relations hypothesis, which contends that the relations of component skills, including reading comprehension, to written composition vary as a function of dimensions of written composition. Specifically, we investigated: (1) whether…

We developed a sustained content literacy intervention that emphasized building domain and topic knowledge from Grade 1 to Grade 2 and evaluated transfer effects on students' reading comprehension outcomes. The Model of Reading Engagement (MORE) intervention emphasizes thematic lessons that provide an intellectual framework for helping students…

We investigated the dimensionality of various indicators of reading prosody, and the relations of word reading and listening comprehension to the identified dimension(s) of reading prosody, using longitudinal data from Grades 1 to 3. A total of 371 English-speaking children were assessed on oral text reading, word reading, and listening…

Metacognition is theorized to play a central role in children's mathematics learning. The primary goal of the current study was to provide experimental evidence in support of this role with elementary school students learning about mathematical equivalence. The final sample included 135 children (59 first graders and 76 second graders) who…

In this study, we investigated longitudinal reciprocal relations among reading, executive function, and social-emotional skills in students from Grades 2 to 5, using the data set from the Early Childhood Longitudinal Study, Kindergarten Class of 2010-2011. We addressed several important gaps in the literature on longitudinal reciprocal relations…

This cohort-sequential study explored the working memory (WM) structures that underlie growth in mathematical word problem solving (WPS) performance in elementary school emergent bilingual children whose first language (L1) is Spanish. To this end, children (N = 429) in Grades 1, 2, and 3 in southwest U.S. school districts at Wave 1 were…

Achievement emotions have received increasing attention in research on adolescence and young adulthood, but little is known about these emotions in the early years of schooling. Studies addressing the development of different achievement emotions and their linkages with achievement during these years are largely lacking. The present longitudinal…

Both mathematics anxiety and metacognitive monitoring have been identified as associated with or predictive of individual differences in arithmetic achievement in primary school children. Although there are various theoretical reasons for an association between mathematics anxiety and metacognitive monitoring, it is unclear at the empirical level…

Does the timing of children's formal understanding of mathematical equivalence matter for algebra readiness? A change-resistance account (McNeil & Alibali, 2005) predicts that it is beneficial for children to construct a formal understanding of mathematical equivalence in the early grades before overly narrow operational patterns become…

Some children struggle with mathematics. Among these children, some of them may be learners with mathematical difficulties. While research has revealed multiple deficits as candidate causes for mathematical difficulties and probable subtypes, the cognitive profiles of these subtypes are not fully understood. Moreover, we have yet to discover…
