We report the validity of a test instrument that assesses the arithmetic ability of primary students by (a) describing the theoretical model of arithmetic ability assessment using Wilson's (2004) four building blocks of constructing measures and (b) providing empirical evidence for the validation study. The instrument consists of 21…

Students' understanding of the meaning of the equal sign develops slowly over the primary grades. In addition to updating their representations of equations to recognize that the equal sign represents an equivalence relation rather than signaling an operation, students need to move beyond full computation to efficiently solve equivalence problems.…

The current study investigated perceptual simulation and its relationship with literacy ability in Chinese children. Ninety-three third-grade Hong Kong Chinese children completed a sentence-picture verification task for perceptual simulation. In this task, a sentence mentioning an object was presented first, followed by a picture involving the…

The importance of early childhood narrative skills in social relationships and children's internal capacity is of utmost interest to be studied. This aim of this study is to examine how the social group functioning, narrative skills, school success and non-verbal intelligence are interconnected. This is a mixed design study with a sample of 109…

We aimed to investigate the effects of phonological awareness -- PA, rapid automatised naming -- RAN, visuospatial and verbal working memory -- WM and executive functions -- EF on the reading and arithmetic skills of children with low- to medium-performance levels. Participants were 472 Brazilian children from 3rd to 5th grades. Quantile…

In Canada, approximately 12% of school-aged children are enrolled in French Immersion (FI), with some provinces estimating close to 30%. FI programs are intended to produce bilingual individuals who can functionally communicate in both of Canada's official languages. Yet, we are currently underinformed as to how to identify children with French…

This study examined the relations among family socialization, loneliness, linguistic skills, and reading comprehension in 78 Mandarin-speaking Chinese third graders with a mean age of 8.67 years old. The participants were administered a battery of tasks to assess their non-verbal intelligence, linguistic-skills, word reading, and Chinese reading…

This study investigated which domain-specific and domain-general skills measured at grade 1 predict mathematical learning difficulties (MLD) status at grade 3. We used different cut-off criteria and measures of mathematics performance for defining the MLD status. Norwegian children's (N = 206) numeracy, cognitive, and language skills were measured…

Background: In countries with German as an official language, children with German as a second language perform overall worse in school than their German native speaking peers. This particularly affects written language skills, which require advanced language knowledge. The reasons are manifold, but one is prominent, namely poor vocabulary…

This study examines the relationship between perceived stress, nonverbal cognitive functioning, and statewide academic scores in both Latinx and European American elementary students in rural school districts. A total of 44 third graders participated in the study, including 13 Latinx students and 31 European American (EA) students. Perceived…

This study examined whether visual-spatial attention could predict Chinese reading achievement longitudinally beyond some well-established reading precursors. A total of 257 second- and third-grade Hong Kong Chinese-speaking children participated in the study. Visual-spatial attention was measured by visual search tasks, which assessed the skills…

Purpose: We investigated the cognitive and linguistic processes that underlie reading in Arabic in relation to a well-defined theoretical framework of reading and the factors that underlie reading. Method: The sample was 201 (101 boys, 100 girls) 3rd-grade Arabic-speaking children. Children were administered measures of Vocabulary, Phonological…

The study aimed to investigate variations in addition and subtraction fluency by observing grade three students in Norway (n = 253, M[ subscript age] = 8.38 y.) and Finland (n = 209, M[subscript age] = 9.35 y.) while controlling for their age and non-verbal reasoning. Gender differences were also examined. The focus of the study was on the…

Academic language has been shown to significantly contribute to success across school subjects. However, to date, there are no empirical studies addressing its development across primary school age. The present study investigated the growth of academic vocabulary and influential conditions from Grades 2 to 4 based on a newly developed and…

The goal of this study was to explore the relationship between morphological awareness and the spelling of morphemes and morphologically complex words among 75 third- and fourth-grade Francophone students of low socio-economic status. To reach this objective, we administered a dictation comprised of morphologically complex words with prefixes,…
