This large-scale study characterizes the algebraic learning of a cohort of nearly 800 French students during the last year of middle school (9th grade, 14-15 years old) and examines their evolution in relation to the composition of the classes to which the students belong. Based on the Anthropological Theory of the Didactic (ATD), the study is…

Angularity is a persistent quantity throughout K-12+ school mathematics, and many studies have shown that individuals often conflate angularity with linear attributes (e.g., the length of an angle model's sides). However, few studies have examined the productive ways in which students might reason about angularity while attending to linear…

STEM Problem solving necessitates a substantial amount of specialized domain knowledge. An important element of problem-solving within the domain includes how knowledge is structured and organized in memory to facilitate efficient retrieval of relevant information and future problem solving. In previous studies, however, problem solving and…

Background: There exist shared competencies between computational thinking (CT) and mathematics, and these two domains also mutually benefit from various teaching approaches. However, the linkages between mathematics and computational thinking lack robust empirical support, particularly from student-centered learning perspectives. Our study aimed…

South African learners' performance in mathematics, both locally and internationally, has raised significant concerns, particularly in the realm of algebra. To address this issue, a mixed-methods study was conducted to explore the effectiveness of using algebra tiles to teach algebraic expressions. The study aimed to investigate algebraic…

The purpose of this qualitative case study was to understand teacher and administrator perspectives regarding how a ninth-grade transitional course that began during the fall of 2019 meets student needs during the transition from middle to high school. The high school in which this study was conducted, is referred to as "Midwestern High"…

School burnout, defined as prolonged feelings of exhaustion, cynical attitude and inadequacy feelings towards schoolwork, can lead to mental problems during adolescence. To find effective ways to prevent burnout, this study examined the synergistic role of two positive personal resources, a stress-is-enhancing mindset and academic buoyancy in…

The purpose of this mixed-methods study was to explore the impact of informal STEM education on underrepresented middle school girls. The study took place within the context of the EUREKA! summer program, a collaboration between Drexel University's Department of Civil, Architectural, and Environmental Engineering and Girls Inc. of Philadelphia and…

This study explores the self-efficacy and problem-solving skills of middle school mathematics students. The students -- 111 9th graders who were studying a unit for the analysis of function -- were given mathematics instruction that was based on either dynamic or static visualization. Findings revealed a positive impact of instruction that was…

Over the last two decades, several studies have overlooked at-school belonging and engagement, two dimensions that are associated with several positive outcomes. However, the relative influence that contexts and interventions may have on these components has received much less attention. In this study, school belonging and engagement were examined…

Mathematics interest is highly relevant for students' academical and emotional development in the domain of mathematics. Thus, it appears alarming that students' mathematics interest decreases during the course of secondary school. Teacher self-efficacy is a central facet of teacher motivation and is assumed to be highly relevant for student…

To increase engagement with science and technology, young people around the world are encouraged to attend activities at science centers. But how effective are these activities? Since women have weaker ability beliefs and interest in technology than men, it is especially important to learn how science center visits affect them. In this study, we…

Problem-based learning (PBL) has the potential to enhance both cognitive and affective engagement but has been criticised for being unsuitable for learners with low levels of knowledge and skills, such as South African learners from poor backgrounds. In such cases, guided problem-based learning (GPBL), which includes direct instruction and teacher…

Reading amount is decisive for individual students' academic success as well as for the general strength of democratic societies. Still, the amount of both leisure-time and school-related reading is decreasing. To reverse this trend, more knowledge of what drives students' school reading is needed. Drawing on Self-Determination Theory (SDT), the…

Some results of the basic school (14 years old) students' information and communication competence (ICC) in the digital environment study are discussed. About 30,000 students (14 years old) took part in the study. Information and Communication Literacy is considered as the ability to use digital technologies to search, manage, integrate, evaluate…
