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…

Although gender gaps associated with K-12 science achievement have narrowed significantly, gaps in science engagement and efficacy in childhood likely explain why women remain underrepresented in science careers. Early intervention programs may address root causes of gender gaps in science careers. Outdoor science education (OSE) is one…

Preventing smoking among adolescents is critical. This study evaluated the effectiveness of the Smoking Prevention Education Program among nonsmoking adolescents. A quasi-experimental study design was used. Data were collected from Year 5 students (n = 140) from four government primary schools in the Kuantan and Pahang districts of Malaysia. The…

Children's health literacy is a crucial pillar of health. This study is aimed to examine the association between health literacy and weight status among Greek schoolchildren aged 10 to 12 years old. A population-based, cross-sectional observational study enrolling 1,728 students (795 boys), aged 10 to 12 years old, was conducted during school…

Early adolescence and the transition to middle school bring about many challenges for students and negative outcomes are not uncommon, including academic decline and social maladjustment. This developmental period is also marked by increased risk of mental health-related difficulties. Strengthening students' social and emotional competencies…

Previous studies on students' conceptions of learning science (COLS) have focused primarily on formal environments. In these studies, students' COLS were positively associated with their approaches to and outcomes for science learning. However, little research has been conducted to explore students' conceptions of learning science in informal…

The article deals with mathematical literacy in relation to mathematical knowledge and mathematical problems, and presents the Slovenian project NA-MA POTI, which aims to develop mathematical literacy at the national level, from kindergarten to secondary education. All of the topics treated represent starting points for our research, in which we…

This small study sought to determine students' knowledge of multiplication and division and whether they are able to use sets of bundling sticks to demonstrate their knowledge. Manipulatives are widely used in primary and some middle school classrooms, and can assist children to connect multiplicative concepts to physical representations.…

With the continuous development and innovation of information technology, virtual reality (VR) has become an important topic of education technology in recent years. VR is not only applied in many industries, but is also used by scholars for education applications as it enables students to have an immersive learning experience to enhance their…

The present research explores benefits of using young students' drawings in combination with written responses for gathering information about science concepts. Younger students are still very limited in their verbal expression and less biologically literate than older students. The aim was to determine primary school students' conceptions about…

Social networking sites (SNSs) are popular technologies used frequently among youth for recreational purposes. Increasing attention has been paid to the use of SNSs in educational settings as a way to engage youth interest and encourage academically productive discussion. Potential affordances of using SNSs for education include knowledge…

Purpose: The purpose of this paper is to explore Swedish children's positive experiences of health and well-being, and their thoughts on how health literacy can be promoted. Design/methodology/approach: Totally, 121 schoolchildren between the ages of 10 and 14 from three schools in two municipalities in the northern part of Sweden shared their…

Early mathematics knowledge is a strong predictor of later academic achievement, but children from low-income families enter school with weak mathematics knowledge. An Early Math Trajectories model is proposed and evaluated within a longitudinal study of 517 low-income American children from age 4 to 11. This model includes a broad range of math…

Children's understanding of the inversion concept in multiplication and division problems (i.e., that on problems of the form "d multiplied by e/e" no calculations are required) was investigated. Children in Grades 6, 7, and 8 completed an inversion problem-solving task, an assessment of procedures task, and a factual knowledge task of simple…

This study reports on CHAMPS, a youth tobacco and prevention program intervention that focused on peer-led educational activities. Nineteen schools implemented a CHAMPS tobacco prevention program in grades 5, 6, and 7. Six schools served as nonintervention comparison sites. Baseline and follow-up questionnaires were completed by 1,412 students.…
