This essay aims to advance the debate on the conceptualization of interdisciplinarity in mathematics education by presenting the idea of the border as a dynamic semiotic cross-cultural space. We refer to three theories, that originate in different research fields and use specific languages: De Luca Picione and Valsiner's idea of the border as a…

In England, there has been a shift away from 'aspiration raising' in widening participation (WP) activities aimed at improving access to higher education (HE) for students from low socio-economic status groups. This shift is partly based on the notion that students from these groups do not inherently "aim lower" However, understanding…

In this paper, we consider the issues involved in creating appropriate problems for a popular mathematics competition, and how such problems differ from problems typically encountered in a classroom. We discuss the differences and similarities in school curricula versus the generally agreed upon topics encountered in international competitions.…

According to expectancy-value models, two important motivational constructs are task value and self-efficacy expectations. As students work intensively on mathematical problems in the classroom, teachers need the competence to judge whether students value solving the problem and how confident they are that they will succeed. However, not much is…

The aim of this survey design study was three-fold. First, to investigate the creative problem-solving attributes of high school students. Second, to examine whether any inter-relationships exist between subdimensions of creative problem-solving attributes. Third, to determine whether high school students' creative problem-solving attributes vary…

In this study, we investigated the connections among teacher-student relationships (TSRs), intrinsic motivation, self-efficacy, and non-routine problem solving (NPS) in mathematics with a moderated mediation model. A sample of 3,101 Chinese ninth-graders (1,654 urban students and 1,447 rural students) participated in a large-scale survey. The…

Self-regulated learning (SRL) represents a necessary fundamental 21st century skill for children and adolescents and is essential for the development of gifted students. This study explored mathematically gifted (MG) junior high school students' SRL capabilities while solving mathematical problems compared to typical achievers (TAs). A sample of…

The background of this research began with an apprehension of the need for students' learning in accordance with their learning abilities relating to the application of a flipped classroom model in the Biology class of XYZ Senior High School. Preliminary research showed the different needs of individual students; thus, differentiated learning was…

In summer 2020, Northeastern University developed a fully online curricular pathway for incoming fall first-year undergraduate students who could not learn in residence. This pathway included 18 Global Challenge (GC) courses, each designed around project-based learning (PBL), grounded in a complex problem defined by Northeastern University…

High school students need to be prepared for postsecondary education and enter the workforce to solve real-world problems including food and energy sustainability. Real-world problems require students to apply critical thinking and problem-solving skills and transfer their learning across disciplines. Framed as a grand challenge to students, the…

Student achievement in learning mathematics is considerably low in Indonesia. This study aims to discuss factors affecting learning achievements in mathematics in Indonesia, including direct and indirect influences, such as students' perception of teacher competence, learning anxiety, problem-solving ability, learning motivation, and mathematical…

Realistic Mathematics Education (RME) has gained popularity worldwide to teach mathematics using real-world problems. This study investigates the effectiveness of elliptic topics taught to 10th graders in a Vietnamese high school and students' attitudes toward learning. The RME model was used to guide 45 students in an experimental class, while…

Conjectures are a key component of mathematical inquiry, a process in which the students raise conjectures, refute or dismiss some of them, and formulate additional ones. Taking a design-based research approach, we formulated a design principle for personal feedback in supporting the iterative process of conjecturing. We empirically explored the…

This study aimed to examine the effect of cooperative problem-solving method on grade nine secondary school students' motivation towards learning algebra. In this study, pretest-posttest non-equivalent group quasi-experimental design was employed. The data were collected from 142 grade ninth students using mathematics motivation questionnaire and…

This study explored how instructional guide documents and high school engineering teachers understand the concept of mindset and the instructional practice of feedback as students engage in classroom problem-solving activities. From data analysis, several important conclusions were made. High school engineering teachers create a classroom climate…
