Early adolescence is a time of rapid cognitive, psychosocial, and physical development, and an array of contextual factors, such as systemic racism, exert significant influence. Universal behavioral health screening data of 4,234 middle school students were examined to explore the influence of demographic (e.g. ethnicity, race) and contextual…

Teachers' own level of human capital development is commonly believed to be deterministic for the quality and effectiveness of their instruction and management in the classroom. Yet, there still exists an international debate on whether better educated teachers contribute to students' cognitive development. Leveraging a random class-assignment…

The Rhythmic Arts Project (TRAP) curriculum integrates visual, tactile, auditory and speech experiences through rhythmic drumming actions to address life skills. We evaluated life skills before and after participation in TRAP in a school-based setting in children with Autism Spectrum Disorders (ASD). Participants were 23 children in grades 6-12 in…

Developing algebraic thinking is a key factor in learning mathematics. Despite its importance, many students still struggle with algebraic concepts. This research investigates students' achievements in algebraic thinking using Demetriou's test across 7th (approximately 12-13 years old), 8th (approximately 13-14 years old), and 9th (approximately…

Algebra is critical in shaping future mathematics success and is integral to the K-12 curriculum. Despite its inclusion, a common challenge arises as students' progress to higher grades without a solid foundation, resulting in challenging learning experiences. This action research study focuses on the algebraic learning experience of a Grade 7…

A qualitatively oriented mixed methods case study was conducted to investigate the effects of incorporating LEGO robotics into a 7th-grade mathematics curriculum. Using the lenses of Social Constructivist Theory and the Five Stages of Technology Integration, this research focused on the development of proportional reasoning skills. The data show…

Abstraction is one of the most fundamental ideas in computer science (CS), and as such, according to Bruner, it should be taught spirally, starting as early as possible and revisited at every level of education. However, teaching CS abstraction to novices is a very challenging task, and CS educational research has often demonstrated students'…

Researchers attempting to show that music has positive effects on children need to understand and control for preexisting differences between those who do and do not select into musical participation in the first place. Within a large-scale, communitywide, prospective, longitudinal study of predominantly low-income, ethnically diverse students (N…

Scientific modeling (SM) is a core practice of science and an important component of scientific literacy. Supporting students in developing the competence to construct, use, evaluate, and revise models is hence of particular relevance. While research has shown that spatial visualization (SV), a core component of spatial ability, is correlated with…

This research study presents the PGBE model for teaching and learning percentages with students of Grade 7 when their cognitive development enables the conceptual understanding of percentages as proportional statements, and offers the possibility for more effective matching of them with fractions and decimal numbers. The abbreviation PGBE presents…

An online system leveraging self-explanation was developed. The theoretical basis and design principles guiding the development of the system were explicated. Four evaluation studies were conducted to assess the student-generated explanations component accompanying student-generated questions (SQG) and the embedded designs. The analyzed data…

The aim of the present study was to investigate the effects of an intervention on students' achievement and motivation. The intervention was in the form of an instructional approach named Dual-Approach Instruction since it was designed to facilitate both the cognitive and non-cognitive aspects of students' learning. The intervention effects were…

Extensive research has demonstrated the impact of working memory (WM) on first language (L1) reading comprehension across age groups (Peng et al., 2018), and on foreign language (FL) reading comprehension of adults and older adolescents (Linck et al., 2014). Comparatively little is known about the effect of WM on young FL readers' comprehension,…

Purpose: This study sought to explore students' experiences of the Fitness Integrated with Technology (F.I.T.) unit and of their perceptions of using technology in physical education. Method: This manuscript is part of a larger mixed-methods study that measured student attitude and physical activity (PA) levels of 221 students in sixth, seventh,…

How likely is the glass to break, given that it is heated? The present study asks questions such as this with or without the premise "if the glass is heated, it breaks." A reduced problem (question without premise) measures the statistical dependency (conditional probability) of an event to occur, given that another has occurred. Such…
