Digital game-based learning (DGBL) can be regarded as a promising teaching pedagogy to prepare students for challenges of the 21st century. However, the incorporation of digital games into K-12 curricula remains limited. Research suggests that a comprehensive understanding of barriers and motivational factors that teachers face when implementing…

This study investigated how Japanese curricula represent functional relationships through the lenses of quantitative and covariational reasoning. Utilizing both macro and micro textbook analyses, we examined the tasks, questions, and representations in the Japanese elementary and lower secondary course of study, teachers' guide, and textbooks.…

This study examines equitable grading practices in secondary mathematics from the student perspective. Youth participatory action research (YPAR) provided a vehicle for high school students to investigate equitable grading, research impacts grading had on their collective, and develop solutions to inequitable grading. It provided opportunities for…

Propositional teacher knowledge is recognised as valuable in classroom teaching practice, yet little attention has been paid to it relative to practical knowledge. This mixed-methods study aimed to understand the relationship between teachers' propositional knowledge and their classroom teaching practice in the collaborative school context using…

One of the aims of the present study was to reveal and compare the performance of ChatGPT versions (GPT-4o, GPT-4, and GPT-3.5), MathGPT, and Gemini in solving 390 mathematical problems in interactive mathematics e-textbooks across various dimensions. The other aim was to identify the affordances and constraints of ChatGPT through the instrumental…

The following survey study uses a quantitative research design to investigate motivational and affective aspects of students (aged 14-17) in a mathematical workshop on graph theory. Motivational and affective aspects are related to heart rate measurement (using the digital medium of a pulse watch) in mathematical knowledge development processes in…

This study investigated task contextualization as a means of assessing students' ability to apply their subject knowledge to new situations. Through analyzing 527 Functional Mathematics examination questions that claim to assess students' application skills, it developed a set of principles for embedding questions in context: deep…

Despite the long-time call for change in mathematics instruction, there are several barriers to change, and instruction has remained stagnant overall, taking the form of traditional lecture. Instructional coaching has many of the attributes of effective professional development from the literature and could be a major support for instructional…

This quantitative descriptive study, a collaborative effort of the research team and 316 Alabama public high school leaders is significant as it identifies the intervention strategies used in Alabama's public high schools and the school principals' perceived effectiveness of these strategies in improving student performance on the math portion of…

Recent research in mathematics education shows that by exploring the properties of figures and making conjectures, especially through dynamic geometry software, students can better develop their understanding of concepts. Furthermore, comparing different geometric worlds and, within them, different representations enhances Euclidean knowledge. In…

Background: Our article argues that the role of translingual instruction in mathematics classrooms is under-recognised in South Africa, as policymakers, teacher educators, teachers, learners, and parents assume that mathematics is just about numbers and calculations and not language. This is despite findings on the value of using children's…

One goal of mathematics education is to adapt features of digital learning materials to students' characteristics. This paper presents a multi-layered research approach to identify key aspects of mathematics students within the persona approach. Data for this research was collected from 5,624 mathematics students using an instrument focusing on 15…

This convergent parallel mixed-methods study examines the relationship between high school mathematics teachers' research-based instructional practices and students' learning outcomes in Algebra 1 classrooms at a high school in a central region of a Southern U.S. State. The research addresses improving mathematics proficiency in the United States,…

This study examines the relationship between the past experiences of secondary education students with their current image of mathematics. It is based on the premise that the image of mathematics is formed through experiences mediated by school, parents, peers, and society. Drawings and interviews were used to explore these experiences. The…

ChatGPT has become a significant topic of interest in the field of education, prompting of the potential applications of such technology. The utilization of ChatGPT may facilitate the fostering of 21st century skills, such as computational thinking (CT) and technology, which could subsequently provide a means of offering students personalized…
