ChatGPT was a learning revolution known as an online program for learning Algebra; it changed what we knew about the teaching medium and molded the learning platform into a more engaging way of teaching. This research determines the use of ChatGPT in addressing math anxiety and promoting the confidence of college students enrolled in algebra at a…

Self-efficacy, the beliefs learners hold about what they can do, develops largely from whether learners perceive and interpret their experiences as successful (i.e., perceived mastery). In mathematics, the relationship between perceived mastery and self-efficacy has been well established. Less is known about the factors that may influence…

Background/Context: Student mathematics performance is an important predictor of future outcomes, from future academic performance (Balfanz et al. 2007; Siegler et al., 2012) and mathematics identity (Bishop 2012; Boaler & Greeno, 2000; Ellis et.al., 2014) to college enrollment and career trajectories (Shapka et al., 2006). Yet, students in…

Mathematical modelling is an interlinking process between mathematics and real-world problems that can be applied as a means to increase motivation, develop cognitive competencies, and enhance the ability to transfer mathematical knowledge to other areas of science, such as engineering disciplines. This study was designed to investigate the effect…

Mastery of the cardinality principle (CP) is foundational for children's mathematical development. Children's age and subitizing and counting skills contribute to their CP acquisition. This study aimed to investigate the effectiveness of different types of instruction for supporting 3-4-year-olds' CP development and its interplay with child…

The main purpose of this study was to explore the effects of two college-level mathematics courses on preservice elementary teachers' mathematics anxiety and mathematics teaching self-efficacy beliefs. For this purpose, a quasi-experimental study was implemented on two college-level mandatory mathematics teaching methods courses that were…

When children are aged around 2 years, many of the early foundations of mathematical skills are developing. Understanding this is important to shed light on theories of mathematical development. Nevertheless, little research has investigated 2-year-olds' early mathematical abilities, with most research focussing on either infants (aged 0-1 years)…

The aim of this systematic review and meta-analysis was to identify and evaluate the effects of individual characteristics associated with mathematical word problem-solving skills among elementary school-aged children and to unpack the quality of studies investigating these associations. The systematic review was reported according to the…

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…

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,…

In this paper, we describe our extension of the action, process, object, schema (APOS) theory to capture the complex interplay of mathematics and physics. We do this in the context of the 2D heat equation. We describe a hypothetical learning trajectory of the 2D heat equation, a preliminary genetic decomposition that stresses the conceptual…

In this study, we explored elementary school teachers' experiences working on open-ended mathematics tasks during a 10-day professional development (PD) workshop. Teachers engaged with the tasks daily in a session call Morning Math (MM). Thirty-two elementary teachers from three school districts in the USA participated in a 2-year professional…

Research on the interaction between curricula and textbooks--particularly the textbook development process--is critical for understanding their reciprocal influence. While mathematics textbooks are typically developed in response to curriculum revisions, textbook research can also inform and shape subsequent changes to the curriculum. This study…

This article investigates the potential mathematical learning opportunities arising from a digital activity designed to enhance students' comprehension of equations. Employing a commognitive-oriented lens, the analysis explores the potential mathematical discourses that could emerge from students' interactions with a digital scale inspired by the…
