We studied the effect of the number and characteristics of siblings (sex, age) on school achievement in several grades (kindergarten, first grade, and fifth grade), in two large French cohorts, with more than 16,000 children. Running linear mixed-effects models, we find that, independently of socioeconomic status, having more siblings is…

Based on 1,364 children across Grades 1, 3, and 5, the present study explored the mutualism of (externalizing and internalizing) behavioral problems and language, and whether social skills explained such mutualism. The random intercept cross-lagged panel models were conducted to control for between-person level variance and to explore mutualism of…

Background: The coherence of learners' pre-instruction conceptions has been debated for some time. Studies on conceptions of force, specifically, have produced very different results in different contexts around the world. In this study, an integrative theoretical framework linking semantic differences across languages to concept learning in…

This comparative study analyzed the similarities and differences in the mathematical communication used by teachers and primary school students in Japanese, Lao, and Thai mathematics classrooms. It adopted a qualitative research design, and the targets were teachers and students in Grades 1-6 at a selected school in each of the three countries.…

Reading interest serves as an inherent driving force for children's reading. Current research shows that family cultural capital, school reading environment, and community reading culture all influence children's reading interests. According to the "family-school-community" collaborative education model, families, schools and communities…

Students in Title 1 school districts continue to fall far behind their peers academically in comparison to neighboring suburban districts. School reform has unsuccessfully attempted to improve test scores by consistently changing reading curriculums and mandating the use of various resources that fail when implemented. Struggling school districts…

The role of children's receptive vocabulary knowledge in word and nonword reading (decoding) in an orthographically transparent language is debated. Moreover, we have little understanding of how the role of vocabulary might differ between monolingual children and bilingual children from immigrant families (or language minority bilingual children…

Young children can struggle to learn difficult disciplinary content and important skills for practicing science. Problem-based learning (PBL) may be useful for addressing such difficulties, yet evidence to support its usefulness in elementary school-aged children is limited. We considered the role of a PBL unit in improving students' genetics…

The paper contains progress reports supported by data about two short activities aimed at introducing physics themes in primary school. The first is a formal storytelling intervention named "Mommy Comet" carried out in first- and fifth-grade classes and concerning motion in the absence of forces in the Solar System broad context. The…

Theoretical perspectives within disciplinary fields are often characterized by initially dichotomous frameworks that become more integrative over time. Indeed, popular discourse on the Science of Reading emphasizes dichotomous contributions of word reading and language comprehension to reading. Yet, these skill sets are inherently complex,…

Differentiation and achievement grouping are frequently implemented practices to adapt education to students' varying educational needs based on achievement level. Potential didactical and socioemotional advantages and disadvantages of these practices have been discussed in the literature. However, little is known about the perspective of students…

The serial advantage, defined as the gain in naming rate in the serial over the discrete task of the same content, was examined between grades and types of content in English and Greek. 720 English- and Greek-speaking children from Grades 1, 3, and 5 were tested in rapid naming and reading tasks of different content, including digits, objects,…

Measures of 31 Latinx students' attitudes in a Grade 5 Spanish dual language bilingual education (DLBE) program were compared with those of the same students four years prior. Twenty-one mainstream English students comprised a comparison group for the same time period. Some statistically significant changes occurred for students in DLBE related to…

A meta-analysis of single-case design research was conducted to evaluate the effectiveness of mathematics interventions for elementary grade (K-5) students with mathematics difficulties (MD) and mathematics learning disabilities (LD). The study examined whether intervention effectiveness varied as a function of participant characteristics (i.e.,…

The Olympics is one of the world's biggest marketing platforms and, as such, presents the private sector with a vast range of advertising opportunities. One new area of opportunity is school-based Olympic education. While previous studies have revealed some of the marketing strategies used by Olympic sponsors in Olympic education, there is still a…
