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…

For the proper development of writing, teachers must choose the best line for their students. To this day, it is still not very clear which is the correct or the most suitable letter for the beginning of this learning process. However, there are certain parameters that allow us to observe the "pros" and "cons" that have been…

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…

The importance of reading competence has been increasingly acknowledged in the Swedish educational system, not least through the demands for higher standards in reading in all subjects stated in the national curriculum. Still, in the school year 2018/19, approximately 7% of all Swedish pupils did not achieve the learning goals related to reading…

This longitudinal study examined the effectiveness of a progress monitoring method, namely the Multilayer Instruction Model-Progress Monitoring (MIM-PM), which is a word reading fluency measure. It was used from 1st grade onward to predict the overall reading achievement of students in elementary school by tracking their reading achievement over…

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…

Self-regulation forms the rudiments for children's academic achievement and socialization. Although one's executive control and verbal skills are needed in both of the core aspects for academic performance: processing to regulate one's own learning and behavior, young students' cognitive capacity for that is still immature influencing the…

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…
