The aim of this paper is to contribute to the ongoing discussion about the role of intuition and ambiguity in doing, teaching and learning mathematics. We start by discussing the ways in which limits and continuity are presented in Calculus textbooks, to illustrate some of the ambiguities, and to contrast them with precise and rigorous definitions…

This study investigates the ability of ChatGPT to generate mathematical problems creatively, focusing on fluency, flexibility, and originality. The findings indicate that ChatGPT can produce a vast number of problems, demonstrating a high level of fluency. Additionally, it tends to prioritize the most original problem among its generated outputs.…

This paper reports on an innovative project which enhanced professional learning for in-service and pre-service teachers in a regional setting. By fostering collaborative mentor-mentee relationships and co-designing professional development activities, the project improved mathematics teaching practices and student outcomes. Utilising Breakspear's…

Facilitating whole-class discussions based on tasks that support inquiry and provide conceptual learning opportunities has been identified as a central, challenging task of teaching. We drew upon practice-based and interactionist research traditions to decompose how eight experienced Grades 5-7 mathematics teachers facilitated whole-class…

Early mathematics education presents middle-school students with the challenge of adding and subtracting negative integers. This paper reports on results from the experimental implementation of a proposed educational design for integer arithmetic that utilized the number-line (NL) form as a resource for students to enact simple addition and…

Place value competence in early years mathematics is a precursor for success in later grades. In this paper, we analyse the place value visual representations in workbooks from South Africa, Singapore and Australia. A cross-country comparison of curricula materials provides an opportunity to understand similarities and differences in use of visual…

Curriculum reform is an opportunity to refresh programs to meet the needs of current students, but this is not without significant investment from teachers. In this exploratory multiple case study, semi-structured interviews captured teachers' processes of curriculum interpretation for mathematics planning and teaching in a school using scripted…

Although absolute value is of interest to mathematics teaching researchers, since many students face problems with it, there does not seem to be an integrated record of students' errors. The present study attempts to conduct a systematic review to identify and categorize errors and misconceptions of secondary school students aged 12-18 concerning…

The Reading and Appreciating Mathematical Proofs (RAMP) project seeks to provide novel resources for teaching undergraduate introduction to proof courses centered around reading activities. These reading activities include (1) reading rich proofs to learn new mathematics through proofs as well as to learn how to read proofs for understanding and…

This study addresses a gap in the empirical research about how students use computational thinking (CT) skills throughout the problem-solving process, which is a crucial skill for STEM learning. I conducted task-based interviews with two pairs of Year 8 students with strong mathematical problem-solving skills and previous experience in solving…

This research aims to examine recent studies on the dimensions necessary for developing mathematical modelling instruction and established frameworks used in teaching mathematical modelling. The study followed the steps outlined as such: identification, screening, eligibility, inclusion, and data analysis throughout three search engines: ERIC,…

Big Ideas in school mathematics can be seen as overarching concepts that occur in various mathematical topics in a syllabus. For teachers, this knowledge can be used to help students develop a better understanding of mathematics by making visible the central ideas, and connection across topics and across levels. For students, this knowledge can…

This study critically examines the mathematics knowledge of pre-service post-primary mathematics teachers (N = 85) on commencing their Professional Master of Education (Level 9) initial teacher education (ITE) programme across four institutions in Ireland. Given the nature of a consecutive approach to mathematics teacher education, pre-service…

(Purpose) This study aimed to evaluate the efficacy of Imagine Math by comparing the performance of program users and non-users on the NWEA MAP Growth Math assessment. (Methods) Propensity score matching was utilized to compare statistically similar southeastern U.S. charter school students who used or did not use the Imagine Math program during…

This qualitative case study of four middle school and secondary school mathematics teachers examines how teachers' reflective practice supported their selection of strategies that align with the needs of current mathematics education according to the 10 dimensions of mathematics education. The findings suggest that teachers' reflection practice,…
