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…

Prior studies identified effective, but mainly non-digital, homework aids. This research involved 18 middle school students in a lo-fi prototyping study to integrate traditional homework support tools with intelligent tutoring systems (ITS), leveraging rich log data for personalized learning. Feature investigations in standardized diaries, goal…

Teacher scaffolding is crucial to promote students' cooperative learning processes, but little is known about the cognitive attention underlying teachers' scaffolding behavior. This study aims to investigate the scaffolding behavior teachers exhibit while intervening in students' cooperative learning and to explore the relation between teachers'…

In this study reciprocal peer tutoring was implemented in middle school mathematics classes for a six-month period. The effects of this methodology on students' mathematics achievements, mathematics anxiety levels, attitudes towards mathematics, and mathematics self-concepts were examined. Study participants included 768 students in grades 7-9…

Teen dating violence (TDV) is a significant public health problem that can have lifelong consequences. Using a longitudinal, cluster randomized controlled trial (RCT), this study examines whether the "Dating Matters" comprehensive prevention model, implemented in middle school, prevented TDV and negative relationship behaviors and…

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…

This study examined the impact of the levels of fidelity of teacher implementation of a research-based middle school mathematics program, implemented systemically across a district, on student achievement benchmarks. By examining the systemic implementation based on the level of fidelity to the written curriculum, this quantitative study sought to…

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…

Grounded in Self-Determination Theory, this study examined trends in depression and the longitudinal impacts of teacher autonomy support and teacher-student relationships on students' depressive symptoms. A total of 1613 Chinese primary school students (48.17% females) and 1397 Chinese middle school students (47.67% females) completed self-report…

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"…

The purpose of this study is to investigate students' mental models of the marine environment and to further examine how these models are related to their perceptions of marine problems. One hundred twenty-eight ninth grade students from a large harbor city in southern Taiwan completed a survey including a drawing activity and a set of two-tier…

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 the qualitative descriptive case study was to examine the supportive needs of African American female students in the public-school setting. This study was guided by three research questions: What are adults' perceptions of the needs of African American female students in the public-school setting? How do adults who work with…
