While numerous studies have investigated teachers' professional learning through their interaction with resources, the question of how teachers' knowledge evolves at different stages of the instructional process remains underexplored. To address this gap, this article builds on the documentational approach to didactics (DAD) and the theory of…

This article proposes an in-depth mathematics analysis of simple and compound interest through an exploration of the mathematical structures underlying these concepts. Financial numeracy concepts (simple and compound interest, interest rates, interest period, present and future value, etc.) have been added to the mathematics curriculum of the…

Positioning theory [van Langenhove and Harré (1999). Introducing positioning theory. In R. Harre, & L. van Langenhove (Eds.), "Positioning theory: Moral contexts of intentional action" (pp. 14-31). Blackwell Publishers] provides a useful analytical lens to examine how teachers' positioning in moment-to-moment interactions can expand…

Recent mathematics education research highlights the importance of developing rehumanising and critical mathematics pedagogies. The aim of this study is to develop a framework for affective content knowledge in mathematics and to apply that framework to instruction identified as supporting both mathematical learning (ML) and social emotional…

The study evaluates the Mythematix prototype, an innovative adaptive e-learning system designed specifically to enhance secondary school students' understanding and proficiency in mathematics. Utilizing a mixed-methods approach, it combines qualitative and quantitative research methodologies to thoroughly assess students' perceptions and…

Introductory calculus is mandatory for postsecondary science, technology, engineering, and mathematics (STEM) majors (Bressoud, 2015); however, many students do not persist through introductory calculus to further STEM study (Rasmussen et al., 2019). One reason for this may be that students struggle with the prior mathematical knowledge required…

Finding teaching methods that foster students' development of geometric thinking and visualization skills is still a current challenge. This study analyses the effects of the combined use of paper folding and dynamic geometry on high school students' geometric thinking and visualization skills. A quasi-experimental study pretest/post-test design…

Motivation is known to fluctuate, often declining, over time. Research on how motivation changes across school years is ubiquitous, yet little research examines changes in motivation within one school year. In this study, we model how third- through fifth-grade students' mathematics motivation (i.e., expectancies and values) changes over two years…

Despite the recent attention given to multicultural and bilingual teaching, several studies indicate that teacher education programmes in South African higher education institutions continue to instruct pre-service Mathematics teachers in Foundation Phase predominantly in English. This poses difficulties for learners when they start teaching in…

Procedural fluency and strategic competence in operating and mathematizing with natural and rational numbers are based on a flexible and meaningful use of mental models, strategies, and procedures. The study to be presented in this paper pursued the question as to which subdomains or tasks relating to procedural fluency and strategic competence at…

Through instructional tasks, teachers can present content in ways that require students to apply critical thinking, problem-solving, and other cognitive skills. The purpose of this mixed methods collective case study was to determine how teacher-assigned instructional tasks in mathematics impact students' learning of mathematical concepts. In this…

The Cell Phone modeling task centers on a Fermi real-world estimation question. The task and rubric can be used at different grade levels to focus on the modeling process and classroom community. Finding time and space to engage students, especially novice modelers, in mathematical modeling can be a challenge, yet the benefits of modeling are…

A variety of factors are associated with the learning difficulty in mathematics in the context of Pakistani schools. This study explored the different causes of learning difficulties in mathematics faced by primary school students in Karachi, Pakistan. Using a quantitative research design, the data was gathered from the parents and teachers of…

This study focuses on ethical dilemmas that arise in moments of inclusion and equity in mathematics teaching and how they might be tackled through teachers' professional judgment. Skovsmose's inclusive landscapes of investigation approach was used to design the study and to collect teachers' joint reflections on moments of inclusion and equity in…

This paper describes a Lesson Study in which in-service mathematics secondary-school teachers, collaborating with researchers, involve grade 10 students in tessellation problems. The data are collected by an experiment carried out in the context of the "Liceo Matematico" project, with three volunteer teachers. The experiment goal was to…
