We propose the 'flow of a proof' as a construct that relates to the balance lecturers achieve in their presentation between the proof as a whole and its different parts, taking into account various aspects (informal, contextual) of proof classroom presentation. We conducted expert interviews in which we presented two different proofs of the same…

Grasping mathematical objects as related to processes is often considered critical for mathematics understanding. Yet, the ontology of mathematical objects remains under debate. In this paper, we theoretically oppose internalist approaches that claim mental entities as the endpoints of process-object transitions and externalist approaches that…

Research has highlighted the important role that the senses play in mathematics thinking and learning, particularly in the area of visualisation, but also in relation to physical movement. Recent scholarship suggests that sensory experiences are not limited to the five cardinal senses but involve a range of other specific senses as well as…

This research aims to investigate information asymmetry in e-commerce supply chain channels and the impact of the fair preference model on the behavior and returns of channel members. Therefore, by contrasting it with the model in the completely rational case, this research establishes a more realistic principal-agent model and incorporates the…

In this paper we investigate the issue of representation within the "Journal of Mathematics Teacher Education" (JMTE) and the broader academic publishing landscape, particularly focusing on the underrepresentation of authors from various world regions. A questionnaire, distributed globally, aimed to amplify the voices of the…

This paper aims to contribute to the advancement of methodological practice for phenomenographic research by introducing the notion of a "lens of awareness," as a device that can enable researchers to zoom into the detail of the research process (the parts of the whole) and out again to the related context of a phenomenographic study…

This paper presents a competency-based curriculum redesign, whose pedagogical orientation is related to the development of a common training base for professional performance specialized in mathematics training and didactic-pedagogical training. The study contributes to the literature on quality assurance in Mathematics Education and provides…

Professional teaching knowledge interferes with the planning and development of classes, which also relates to integrating digital technologies in the classroom. This study aimed to understand and discuss teachers' professional knowledge for teaching mathematics with digital technologies. The methodology of this systematic literature review was…

The current research aimed to unpack teachers' knowledge of integers by investigating how they used the number line and counter models to represent the two meanings of division (i.e., partitive and measurement). The participants were three middle school mathematics teachers working in different cities in Türkiye. Data consisted of teachers'…

Early academic skills and behavioral characteristics in students are predictive of later school achievement, but academics and behavior are commonly compartmentalized in research and practice. This study investigated to what extent first-grade early numeracy (EN), literacy, and behavior ratings predicted fourth-grade mathematics achievement. In…

This mixed methods study was conducted to investigate mathematics preservice teachers' (PTs) promotion of self-regulated learning (PSRL) with respect to time through participation in a self-regulated learning (SRL) enriched seminar course. PTs' self-efficacy beliefs for promotion of self-regulation (SE-PSRL) over time was also investigated.…

It has been over thirty years since the nuclear reactor meltdown at the Chernobyl nuclear power plant, but why there is still an officially designated exclusion zone? The Chernobyl Disaster Task combines the learning of exponential functions with properties of radioactive substances to help students understand the ongoing effects of the meltdown.…

This qualitative study aimed to identify the changes in a prospective' conceptions about the nature of mathematical tasks and pedagogy in video cases and to investigate the characteristics of the prospective' professional knowledge and views during task design/modification. The study used the mathematical task demand engagement process, which…

The number line estimation task is frequently used to measure children's numerical magnitude understanding. It is unclear whether the resulting straight, horizontal, left-to-right-oriented estimate patterns indicate task constraints or children's intuitive number--space mapping. Three- to six-year-old children (N = 72, M[subscript age] = 4.89, 56%…

Background: Game-based learning can frame problem-solving as a sense-making experience with domain-specific tasks for school students. However, multiple challenges arise when trying to support learners in such a complex, problem-oriented learning environment. Objectives and Methods: With an architecture-themed mathematics learning game, we…
