Previous research examining comparison relations in word problems primarily focused on students' achievements in word problems with one operation. In this paper, we extend previous research to examine the achievement of students of different ages on word problems that integrate compare and combine word problems, hereafter referred to as…

This study examines the usage and effectiveness of Lexercise, a hybrid reading intervention program combining weekly literacy intervention with structured independent practice, in supporting reading skill development among struggling readers. Analysis of 198 students in grades 2-6 during the 2023-2024 school year revealed strong adherence to the…

The study aims to examine students' awareness and reported use of learning strategies as well as their effectiveness for word recognition using a word list memorization task. The sample included 1039 Grade 2, 1069 Grade 4, 832 Grade 6, and 3752 Grade 9 students (aged 8-15 years) from 272 Estonian schools. More students in higher grades reported…

At school entry, girls are rated by teachers as more competent on measures of social skills than boys. It is less clear if this higher rating is stable or grows over time. To address this question, multiple group curve of factors models investigated gender-specific growth trajectories across seven waves of measurement in a large, longitudinal…

The study aimed to investigate the effect of an interdisciplinary STEM course on children's attitudes of learning and engineering design skills. A total of 449 elementary school children in China were recruited from three different grade levels (i.e., second, fourth and sixth grade) to participate in this study. All participants attended a weekly…

Gender stereotypes about science, technology, engineering, and math (STEM) are salient for children and adolescents and contribute to achievement-related disparities and inequalities in STEM participation. However, few studies have used a longitudinal design to examine changes in gender stereotypes across a range of STEM fields. In a large,…

There is a lack of research on students' conceptions of giftedness and intelligence, despite recognition of their influence on real-life factors such as achievement and motivation. This paper presents a cross-sectional mixed methods study that investigated Finnish students' (age 6-16 years; N = 1282) implicit conceptions of giftedness and…

Prior research links need for approval (NFA; the extent to which self-worth is contingent on peer approval or disapproval) to critical developmental outcomes, but little is known about how NFA develops over time or within social contexts. To address this gap, the present study used a sophisticated analytic approach (autoregressive latent…

Engaging key stakeholders, including students into the process of school-based physical activity (PA) intervention planning is considered important. The present study was part of the preparatory phase of the Estonian Schools in Motion pilot programme and aimed to examine students' perspective of PA opportunities in the classroom. Based on 17 focus…

Academic underachievement, as measured on standardised assessments, is commonly reported among students on the autism spectrum. However, little is known about the factors that predict academic (under)achievement, limiting the development of effective and targeted interventions. This study explored teacher ratings of academic skills and enabling…

Growth in working memory capacity, the number of items kept active in mind, is thought to be an important aspect of childhood cognitive development. Here, we focused on participants' awareness of the contents of their working memory, or "meta-working memory," which seems important because people can put cognitive abilities to best use…

One hundred four students aged 8 to 16 worked on one Fermi problem involving estimating the number of people that can fit in their school playground. We present a qualitative analysis of the different mathematical models developed by the students. The analysis of the students' written productions is based on the identification of the model of…

Extensive research has been conducted on summer reading loss among children from low-SES families and children who are struggling readers (Alexander, Entwisle, & Olson, 2001; Allington, et al., 2010; Compton-Lilly, Caloia, Quast, & McCann, 2016; Cooper, Nye, Charlton, Lindsay, & Greathouse, 1996; Heyns, 1978; Parker & Reid, 2017).…

Most studies have concentrated in assessing students' overall attitudes towards science, mathematics, and engineering/technology or the attitude towards individual STEM domain. The present research aims to explore primary students' gender and grade differences of their STEM domain-specific attitudes including self-efficacy and expectancy-value…

The purpose of this research is to compare the previous stereotypes of the scientist image and the current stereotypes of the inventor image among Korean students. For this purpose, three primary schools located in the metropolitan area of Korea were selected under a convenience sampling method, with one class selected for each of the 2nd, 4th,…
