This case study investigated the development of prospective mathematics teachers' technological pedagogical content knowledge (TPACK) in graphical data displays with (VM) within the context of a microteaching lesson study (MLS). This research investigated how five participants integrated technology and implemented a lesson plan aimed to teach…

This study investigates the characteristics of Japanese primary school mathematics lessons that adopt a problem-solving approach. We argue that these characteristics are reflected in three key aspects: collective teaching and learning, the lesson as a "drama" (i.e., its structured flow), and the focus on mathematical knowledge. In this…

This article presents a curricular reasoning model developed based on research conducted with middle grades teachers as they planned, taught, and reflected on a geometric transformations unit. Teachers can use the model to become aware of their own curricular reasoning to make key mathematical decisions as they plan and teach their lessons. While…

We investigate proving activities from a monistic embodied perspective, namely the functional dynamic systems (FDS) approach. Using proofs without words, we focus on proving activities that can be conceptualized as identifying and filling gaps. Using a microethnographic methodology enhanced by eye-tracking, we investigate sensory-motor processes…

Mathematics vocabulary plays a crucial role in students' mathematics learning. However, students, particularly those with learning disabilities (LDs), encounter challenges in understanding and grasping mathematical terms. This challenge becomes more evident as students progress into the elementary and secondary grades, where mathematics vocabulary…

In this paper, we explore the critical practice of making sense of students' mathematical ideas. We extend previous research by studying stances prospective teachers adopt, the extent or depth to which they do so, and the types of prospective teachers making sense of students' mathematical ideas. Analyzing the responses of 123 prospective teachers…

This research aimed to 1) study compositions and indicators towards learning management competencies for enhancing critical thinking of math teachers in secondary schools, and 2) to check construct validity of learning management competencies for enhancing critical thinking of math teachers in secondary schools. The sample group was 260…

In the wake of the present inclusion of programming in mathematics education, which is a feature of curricular revisions in many countries, we have analysed newly inserted programming activities in mathematics textbooks. The aim was to investigate how such activities relate to and potentially affect students' opportunities to learn mathematics.…

The research aimed to measure the effect of educators' teaching effectiveness focusing on content knowledge (CK) and pedagogical content knowledge (PCK) as key determinants. A descriptive survey design was utilised for the study and the participating educators were selected through a simple random sampling method. Four research questions were…

Mathematical modeling tasks can engage students in ways in which they see themselves as mathematicians capable of using mathematics to solve real-world and complex problems. As mathematics teacher educators and researchers, the authors collaborated with two 5th-grade teachers, Liz and Anna (pseudonyms), focusing on equitable practices that foster…

This study examined the types of representations that primary school children create in solving different types of problems, the relationship between these types of representations, and the accuracy rates in solving the problems. The study was conducted with 80 students attending primary school's 2nd and 3rd grades. An achievement test prepared by…

The issue of mathematical knowledge in teaching has been widely discussed over the years. In this study, we carried out a systematic review of the literature with the aim of understanding, quantitatively and qualitatively, the studies developed related to the mathematical knowledge necessary for the teaching of Mathematics, with a focus on Numbers…

The academic success of students in higher education institutions (HEIs) depends on a multitude of factors, including the assessment strategies employed. In recent years, many HEIs have prioritised continuous assessment methods, often as a complement to or replacement for traditional final exams. This study examined the impact of two assessment…

This paper reports on our study of the effectiveness of the course instruction in the numeracy course 'Numbers for Life', offered at McMaster University, Canada, and taught by one of the co-authors. In this course students explore the ways to reason with numbers in a variety of contexts important not only for their individual lives and their…

This study aims to identify the predictors of mathematics teaching anxiety among Filipino preservice elementary teachers. This research utilized a descriptive-correlational research design. Data were obtained through a descriptive survey from 145 students, selected using stratified random sampling from a state university in Central Luzon,…
