This paper provides a longitudinal analysis of the understanding of repetition patterns by 24 Spanish children ages 3, 4 and 5, through representation and the type of justification. A mixed quantitative and qualitative study is conducted to establish bridges between algebraic thinking and computational thinking by teaching repetition patterns in…

Maternal substance use and unpredictable maternal sensory signals may affect child development, but no studies have examined them together. We explored the unpredictability, frequency and duration of maternal sensory signals in 52 Caucasian mother-child dyads, 27 with and 25 without maternal substance use. We also examined the association between…

Integral to the global nature play movement, nature play programs have flourished over the last decade, both in Australia and internationally. Internationally, there are two prominent schools of thought in this movement, Danish Nature Kindergartens, and British Forest Schools. The underpinning philosophy of Danish Nature Kindergarten programs has…

Symbolic numeracy first emerges as children learn the meanings of number words and how to use them to precisely count sets of objects. This development starts before children enter school and forms a foundation for lifelong mathematics achievement. Despite its importance, exactly how children acquire this basic knowledge is unclear. Here we test…

Background: Parent-mediated intervention (PMI) is a potentially scalable approach for tailored interventions in neurogenetic conditions like Down syndrome (DS). Because PMIs require ongoing parent engagement, they must be developed in alignment with the needs of intended users. The present study examined caregiver opinions and preferences to…

Previous research has supported selecting development-matched targets rather than age-matched targets to teach play skills to children with autism spectrum disorder. However, few studies have been conducted, and replications and extensions of this research are needed. The current study replicated Pane et al. (2022) by comparing the acquisition of…

"Research Findings:" Early science skills predict later science achievement, and persistent achievement gaps in science appear as early as preschool. The current study compared the effectiveness of different instructional approaches for teaching preschoolers about sinking and floating and examined individual differences in learning.…

"Research Findings:" Executive Function (EF) and Early Math (EM) are foundational skills for children's school success. Interventions have shown to foster these skills, but their effectiveness in less developed countries remains unknown. This study examined the initial efficacy of an eight-week EF and an EM skills program for young…

This quantitative correlational study investigates caregivers' attitudes toward sexual behavior and sex education for children with Down syndrome, drawing upon the theories of reasoned action and planned behavior. Data was collected from a convenience sample of 112 caregivers. The analysis revealed significant positive associations between…

Number sense is a key indicator of students' future academic success. Students from low socio-economic backgrounds often come to kindergarten lacking number sense skills that other students acquire before they begin formal schooling. Small-group intervention that is focused on number sense skills is an effective way to address this foundational…

Based on the bilingual children's and adults' code-switching (CS) dependency treebanks, this paper investigates the syntactic features and pragmatic functions of the Chinese-English bilingual children's CS and compares them with bilingual adults'. It is mainly found that (1) As to the bilingual children, the mixed sentences present the longest…

Background: Given the growing reliance on digital devices, an increasing number of studies have examined the effects of text medium on reading outcomes in development; however, the results have been mixed. The goal of this systematic review is to look at how print and digital formats affect reading comprehension, engagement and other reading…

Objective: The goal of the present study is to describe the ADHD phenotype from childhood to adolescence in Black and White girls in a community sample. Method: Primary caregivers enrolled in the population-based, longitudinal Pittsburgh Girls Study reported on girls' ADHD symptoms and impairment from ages 7 to 17; diagnostic subtypes were…

Clinicians utilize various methods for narrative sampling, including oral assessments like story generation and retelling, often aided by visual aids. Assessing language skills in deaf/hard of hearing (DHH) children requires careful narrative technique selection. This comparative observational study investigates the narrative outcomes of story…

Quantitative evidence synthesis methods aim to combine data from multiple medical trials to infer relative effects of different interventions. A challenge arises when trials report continuous outcomes on different measurement scales. To include all evidence in one coherent analysis, we require methods to "map" the outcomes onto a single…
