Grounded in the Zone of Proximal Teacher Development (ZPTD) framework, the research examined how AI-mediated interactions support cognitive, metacognitive, and pedagogical dimensions of instructional design. Twenty-two pre-service mathematics teachers participated in a three-phase qualitative exploratory case study involving independent problem posing (Task A), AI assisted problem posing with ChatGPT (Task B), and subsequent written reflections and semi-structured interviews. Thematic analysis of task outputs, interaction logs, and reflective data revealed that ChatGPT provided multidimensional scaffolding (cognitive, metacognitive, strategic, affective, and pedagogical), which collectively enhanced participants’ task quality and depth of reflection. AI-assisted tasks showed notable improvements in contextual relevance, problem structure, cognitive demand, and creativity compared to mathematical problems posed independently. Participants reported substantial shifts in instructional awareness, moving from procedural task design toward student-centred and imaginative problem construction. These findings suggest ChatGPT has potential as a reflective learning partner, supporting development of pedagogical reasoning and instructional creativity in teacher education. The study extends the ZPTD framework to AI-mediated contexts, offering theoretical and practical insights for integrating generative AI into professional learning for pre-service teachers.</p> Baharullah, Sriyanti Mustafa, Sitti Fithriani Saleh, Sri Rahayuningsih, Muhammad Gazali Copyright (c) 2026 Mathematics Teacher Education and Development https://ojs.merga.net.au/index.php/mted/article/view/1568 Thu, 08 Oct 2026 00:00:00 +1000 K–8 Pre-service Teachers’ Evaluation of Existing Geometry Activities That Utilise a Technological Resource https://ojs.merga.net.au/index.php/mted/article/view/1390 <p class="MTEDAbstract"><span lang="EN-AU" style="font-family: 'Palatino Linotype',serif;">Prior research has highlighted the importance of integrating technology into mathematics education, though preservice teachers often do not feel prepared to integrate technology into their classroom upon degree completion. This qualitative, descriptive study sought to examine kindergarten through eighth-grade preservice teachers<em>’</em> (<em>N</em> = 44) evaluation of existing geometry activities that utilise a technological resource. Specifically, the researchers examined the impact that the technological resource utilised in the activity would have on instruction, aspects of the activity that preservice teachers either liked or disliked, and preservice teachers<em>’</em> rationale as to why they would choose to either use or not use the activity in their future K–8 mathematics classrooms. To guide the methodology of this study, the researchers utilised the Passive, Interactive, and Creative—Replacement, Amplification, and Transformation (PICRAT) model. Data were collected from responses to an open-ended prompt as part of a mathematics methods course and analysed with both <em>a priori</em> (i.e., PICRAT) and emergent coding. Findings from the <em>a priori</em> coding showed that the activities evaluated by preservice teachers most frequently utilised a technological resource (often a mathematical game) in a way that aligned with the interactive, amplification level of the PICRAT model. Emergent coding revealed that preservice teachers most frequently liked the content of the activity, disliked topics related to the pedagogical implications of implementing the activity and founded their rationale for future use on pedagogical considerations related to implementation. Implications of the findings are discussed as well as recommendations for future research.</span></p> Monte Meyerink, Fenqjen Luo Copyright (c) 2026 Mathematics Teacher Education and Development https://ojs.merga.net.au/index.php/mted/article/view/1390 Fri, 02 Oct 2026 00:00:00 +1000 Addressing Sustainability in Initial Mathematics Teacher Education https://ojs.merga.net.au/index.php/mted/article/view/1391 <p class="MTEDAbstract" style="margin: 24.0pt 36.0pt 24.0pt 36.0pt;"><span lang="EN-AU" style="font-family: 'Palatino Linotype',serif;">This article presents a scoping review of international peer-reviewed literature (2015–2025) examining how sustainability is addressed in initial mathematics teacher education (IMTE). Guided by five research questions, the review synthesised 24 empirical studies to explore how sustainability is conceptualised, integrated, and challenged in IMTE contexts. Two dominant conceptualisations emerged: “mathematics for sustainable development,” which positions mathematics as a tool for engaging with socio-environmental issues; and ”sustainability of mathematics-related knowledge,” which emphasises the lasting impact of IMTE on prospective teachers’ knowledge, skills, and dispositions. Each conceptualisation gives rise to distinct, yet sometimes overlapping, pedagogical approaches. The former is associated with socio-critical mathematical modelling, interdisciplinary project-based learning, and reflective pedagogy, while the latter foregrounds technology-enhanced instruction, culturally responsive teaching, and development of transferable competencies. Persistent barriers, however, include rigid curricula, limited faculty expertise, conceptual uncertainty, and misaligned policy frameworks. Addressing these challenges requires systemic action through curriculum reform, interdisciplinary professional development, and integration of sustainability competencies into accreditation standards. The review showed how conceptual framings of sustainability inform pedagogical practice, reveal structural obstacles, and guide strategic responses, offering a foundation for reimagining IMTE as a transformative space for preparing mathematics teachers to contribute meaningfully to sustainable futures.</span></p> Constantinos Xenofontos, Aleksandra Khara Fadum, Trude Sundtjønn Copyright (c) 2026 Mathematics Teacher Education and Development https://ojs.merga.net.au/index.php/mted/article/view/1391 Fri, 18 Sep 2026 00:00:00 +1000 Pre-service Teachers’ Conceptions of Mathematical Promise: A Systematic Review https://ojs.merga.net.au/index.php/mted/article/view/1566 <p class="MTEDAbstract" style="margin: 24.0pt 36.0pt 24.0pt 36.0pt;"><span lang="EN-AU" style="font-family: 'Palatino Linotype',serif;">Pre-service teachers’ (PSTs) conceptions of mathematics teaching are reflected in their instructional practices. Understanding what PSTs consider to be mathematical promise can help teacher educators design courses that address these conceptions. This systematic literature review examines PSTs’ conceptions of mathematically promising students (MPS) and the factors that influence these conceptions. The review follows a structured process consisting of literature search, selection, data extraction, analysis, and synthesis. The findings revealed that PSTs hold diverse conceptions about the characteristics of MPS and educational provisions for them. PSTs describe mathematical promise as both innate and developmental, encompassing cognitive, affective, and social dimensions. They emphasise the need for challenge and a supportive learning environment to foster the development of students’ mathematical potential and stress the importance of teachers having a facilitative role. The review also underscores the influence of teacher education on shaping PSTs’ conceptions, although personal school experiences and media portrayals of mathematical promise can also have an impact.</span></p> Miranda Rampe, Eva-Lena Erixon, Kristina Juter Copyright (c) 2026 Mathematics Teacher Education and Development https://ojs.merga.net.au/index.php/mted/article/view/1566 Wed, 07 Oct 2026 00:00:00 +1000 Teacher Beliefs about Constructivist and Instrumentalist Approaches to Mathematics Teaching: An Exploratory Case Study https://ojs.merga.net.au/index.php/mted/article/view/1314 <p class="MTEDAbstract"><span lang="EN-AU" style="font-family: 'Palatino Linotype',serif;">Within a global trend of the narrowing of curricula, the teaching of mathematics through a constructivist approach, where students actively build meaning through inquiry, reasoning and conceptual understandings, is at risk. This exploratory case study, conducted in a medium-sized regional school in Queensland, Australia, sought to understand teacher’s beliefs about mathematics and how these beliefs impact their practice. Findings showed that teachers held mixed beliefs about teaching and learning mathematics and often struggled to use the <em>Australian Curriculum</em> in ways that supported high-quality constructivist approaches to pedagogy, finding it too restrictive. This study highlights the need for targeted professional development to support teachers with pedagogical strategies that align with the intent of the <em>Australian Curriculum</em> and constructivist approaches, ensuring that future 21st‑century learners become confident, creative users and communicators of mathematics.</span></p> Deanna Russo, Melissa Fanshawe, Monique Mandarakas Copyright (c) 2026 Mathematics Teacher Education and Development https://ojs.merga.net.au/index.php/mted/article/view/1314 Fri, 09 Oct 2026 00:00:00 +1000 Assessing Geometric Proof Skills: Instrument Validation Through Reliability and Factor Analysis https://ojs.merga.net.au/index.php/mted/article/view/1265 <p><em>From a mathematics teacher education perspective, identifying the component processes involved in geometric proof reasoning may help prospective teachers interpret learners’ proof attempts and plan instruction. This study examined the internal consistency and empirical structure of a 25-item multiple-choice instrument for assessing proof-related reasoning in geometry. Responses from 275 Indonesian preservice mathematics teachers were analysed using item–total correlations, Cronbach’s alpha, and an exploratory analysis of the instrument’s component structure. The overall internal consistency was high (Cronbach’s α = 0.892), although four items had corrected item–total correlations below 0.30. The reported component analysis yielded a six-component solution accounting for 56.63% of the total variance. The components concern deductive relationships, linking premises, identifying relevant statements, recognising circular arguments, and reasoning with particular and universal propositions. These findings provide preliminary evidence of the instrument’s usefulness for investigating proof-related reasoning. However, weak items, cross-loadings, and the need for further psychometric confirmation mean that its subscale interpretations should be considered provisional. In mathematics teacher education, responses to the instrument may help teacher educators design activities in which prospective teachers analyse reasoning errors and consider appropriate instructional responses.</em></p> Lathiful Anwar, Cholis Sa'dijah, Tomi Listiawan Copyright (c) 2026 Mathematics Teacher Education and Development https://ojs.merga.net.au/index.php/mted/article/view/1265 Fri, 09 Oct 2026 00:00:00 +1000
