The current longitudinal study measured 279 kindergartners' (M[subscript age] = 5.76 years; SD = 0.55; 135 females) place value understanding using both approximate and syntactic measures based on previous evidence that early variation in performance on approximate measures was associated with subsequent syntactic place value understanding. In the…

This study investigated the extent to which domain-general and domain-specific antecedents contributed to pre-algebra's initial level and growth rate among students who experience word-problem difficulty (WPD). We examined if such a profile differs for English-language learners (ELLs; n = 75) and non-ELLs (n = 55) with WPD. We assessed 130 U.S.…

One year after the COVID-19 quarantine, we conducted an eight-week pilot study with third graders (n = 246), who took a repeating knowledge, attitude, and behavior pretest and a reading comprehension posttest from the eBook for Oral Health Literacy© curriculum. Our research questions were: 1) Will the knowledge, attitude, and behaviors of third…

Background: Primary school teachers play an important role in furnishing children with basic knowledge about health literacy and awareness of COVID-19. This study was conducted to determine the levels of health literacy and COVID-19 awareness among preservice primary school teachers and the factors associated with this. Methods: The sample of this…

The present study tests two predictions stemming from the hypothesis that a source of difficulty with rational numbers is interference from whole number magnitude knowledge. First, inhibitory control should be an independent predictor of fraction understanding, even after controlling for working memory. Second, if the source of interference is…

Despite being a critical emergent literacy skill and an indicator of risk for later reading difficulties, relatively little is known about how alphabet knowledge develops over time. This study utilized a person-centered approach and longitudinal sample of 998 preschool-aged children (M = 56.50 months old) to examine patterns in letter name and…

Algebraic competence is a major determinant of college access and career prospects, and equal sign knowledge is taken to be foundational to algebra knowledge. However, few studies have documented a causal effect of early equal sign knowledge on later algebra skill. This study assessed whether second-grade students' equal sign knowledge…

Background: Phonological processing skills have been found to contribute to spelling development across different orthographies; however, less is known about the role of orthographic knowledge. This longitudinal study explores the contribution of phonological and orthographic knowledge to spelling development in a semi-transparent orthography…

Orthographic knowledge is predicted to be central in the process of children's reading development. We examined both the temporal order between orthographic knowledge and each of word reading and word spelling--effectively, which predicts which by including autoregressive controls--and cross-linguistic transfer between English and French for our…

The aim of the study was to examine which predictor variables are related to literacy skills among monolingual Swedish (n = 269) and bilingual Finnish-Swedish (n = 229) children at the first grade in the Swedish-speaking schools in Finland. The participants were assessed in phonological awareness, letter knowledge, rapid automatized naming (RAN),…

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…

This study examined the longitudinal relationship between early handwriting skills and the growth of spelling and reading skills in a large sample (N = 569) of 5- to 6-year-old children unselected for ability. The quality of children's handwriting was assessed using five indicators (letter form, slant, rhythm, ability, general appearance).…

The relationships between phonological awareness, rapid naming, short term verbal memory, letter knowledge, visual skills and word reading in kindergarten, and the predictive patterns from kindergarten to first grade were examined in 41 Chinese-Dutch bilingual children living in the Netherlands in both their first language (Chinese) and second…

Copying characters presented previously (delayed copying) is an important skill in Chinese literacy acquisition. The relations of delayed copying and a set of literacy-related skills (including vocabulary knowledge, rapid automatized naming, phonological awareness, morphological awareness, and orthographic awareness), visual-orthographic judgment,…

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…
