Abstract

Purpose: This study aims to synthesize empirical evidence on the impact of ethnomathematics-based learning on students’ mathematical achievement and attitudes in Indonesia and to examine how education level, mathematical domain, and cultural context influence learning outcomes. Method: A systematic review and meta-analysis were conducted following PRISMA and Cochrane standards on fifteen quantitative studies (n = 1,247) published between 2018 and 2024. A random-effects model was used to calculate effect sizes supported by heterogeneity and subgroup analyses. Findings: Results show a large positive effect on mathematical achievement (d = 1.15) and a moderate effect on learning attitudes (d = 0.69). Stronger impacts were found at the elementary level and in problem-solving tasks. Integrating local crafts, architecture, and traditional games enriched students’ engagement and conceptual understanding. Significance: The findings demonstrate that connecting cultural heritage with mathematics enhances cognitive mastery and positive learning attitudes. Ethnomathematics offers a culturally responsive framework that unites local wisdom with academic excellence, guiding educators and policymakers toward more inclusive and meaningful mathematics education.

Abstract

Purpose: This study investigates how Grade 10 mathematics teachers interpret and enact their questioning strategies to promote critical thinking in financial mathematics classrooms. Specifically, it identifies the types of questions teachers employ, examines the rationales underlying their choices, and analyses how these questioning practices shape opportunities for learners’ critical reasoning. Method: A qualitative multiple-case study design was adopted involving six purposively selected teachers from three public secondary schools in Pinetown, KwaZulu-Natal. Data were generated through semi-structured questionnaires, classroom observations, and interviews. Inductive thematic analysis was conducted, guided by the Revised Bloom’s Taxonomy and the Cognitive Rigor Matrix to categorise the cognitive demands embedded in teachers’ questions. Findings: The findings reveal that teachers employed five types of questions: factual, procedural, open-ended, probing, and adaptive. While all teachers relied heavily on lower-order questioning, only some consistently used higher-order questions. Teachers who incorporated open-ended and adaptive questions created richer cognitive engagement, enabling learners to justify reasoning and explore conceptual connections. By contrast, teachers who relied solely on factual and procedural questions provided limited opportunities for critical thinking to emerge. Significance: This study underscores the pivotal role of higher-order questioning in strengthening critical thinking within financial mathematics instruction. The results highlight the need for targeted professional development that equips teachers to design and implement cognitively demanding questions. Such support is essential for advancing learner engagement, deepening conceptual understanding, and enhancing the overall quality of mathematics teaching in secondary schools.

Abstract

Purpose: Prospective elementary teachers often experience difficulty connecting visual representations with conceptual understanding, resulting in fragmented reasoning about geometric properties. This study aims to examine pre-service teachers’ geometric reasoning using the VLOKS model, with a specific focus on the visual and literal dimensions that frequently hinder the transition from perceptual recognition to conceptual comprehension. Method: A descriptive qualitative design was implemented involving 199 students from the Primary Teacher Education Program at Universitas Tanjungpura. Data were collected through a 12-item diagnostic test, semi-structured interviews, participatory observations, and focus group discussions. Thematic analysis was conducted through data reduction, display, and verification, supported by triangulation of methods and sources to ensure credibility in interpreting students’ visual, literal, operational, correlational, and spatial reasoning processes. Findings: The study found that students’ visual reasoning was largely limited to surface-level recognition of shapes, with little progression toward analytical interpretation. Literal reasoning showed substantial difficulty, particularly in translating verbal descriptions into accurate geometric representations. While operational skills appeared moderately developed, correlational reasoning and spatial visualization were relatively weak, indicating that students struggled to integrate multiple geometric ideas into coherent conceptual structures. Significance: The results underscore that pre-service teachers’ geometric reasoning remains predominantly visual and descriptive, lacking depth in relational and representational understanding. The VLOKS model offers a systematic framework for diagnosing these reasoning gaps and guiding pedagogical interventions. Strengthening the visual and literal dimensions through multi-representational learning, contextual visualization, and reflective reasoning can enhance conceptual understanding and improve teacher readiness in geometry instruction

Abstract

Purpose: This study explore the self-determination profiles of postgraduate mathematics education students, emphasizing how autonomy, competence, and relatedness contribute to their readiness and motivation to pursue teaching as a professional career. Method: A quantitative-descriptive approach was employed, using a validated self-determination questionnaire distributed to 47 postgraduate students and alumni from 2020 to 2024. The instrument measured three SDT dimensions (autonomy, competence, and relatedness) through 24 positive and negative statements. Descriptive and comparative analyses were applied to identify dominant motivational patterns. Finding: Findings revealed high mean scores for autonomy and competence, indicating students’ confidence in decision-making and mastery of pedagogical knowledge. Relatedness also scored strongly, reflecting solid interpersonal engagement with peers and lecturers. Collectively, these outcomes depict a balanced SDT profile among future mathematics teachers. Significance: The study demonstrates that strong self-determination enhances students’ readiness to enter the teaching profession with intrinsic motivation, pedagogical confidence, and collaborative awareness. Strengthening these three SDT dimensions within teacher education curricula can cultivate mathematics educators who are reflective, adaptive, and committed to continuous professional development. This research underscores that fostering autonomy, competence, and relatedness is not only central to improving mathematics learning but also to shaping sustainable teacher professionalism in the modern educational landscape.

Abstract

Purpose: This study investigates how e-modules built on the Understanding by Design (UbD) framework contribute to shaping university students’ conceptual understanding in mathematics. Beyond estimating the size of their impact, the study also looks at how research on UbD and digital learning materials has grown and shifted over the last decade, revealing patterns that often go unnoticed in conventional reviews. Method: To achieve this, the study adopts a Systematic Literature Network Analysis (SLNA), an approach that brings together a structured review, quantitative meta-analysis, and bibliometric mapping. A search of the Scopus database covering 2015–2025 was screened using PRISMA guidelines, resulting in forty studies that met the criteria. Twenty-two of these provided extractable quantitative data for calculating effect sizes. Bibliometric analysis using VOSviewer helped trace recurring themes, keyword relationships, and changes in research direction over time. Findings: The evidence points to a consistent advantage for UbD-based e-modules, with the meta-analysis showing a moderate-to-large improvement in conceptual understanding (g = 0.62). Most studies reported positive results, though the level of UbD implementation played a crucial role—programs that applied the framework more faithfully produced notably stronger outcomes. Network analysis revealed six dominant thematic clusters and showed a gradual movement toward digital pedagogy, assessment alignment, and emerging AI applications. Several gaps remain, particularly in measuring long-term retention and developing reliable fidelity instruments. Significance: The study underscores that the strength of UbD-based e-modules lies not in the technology itself but in thoughtful, goal-oriented design. By pairing empirical synthesis with network insights, the findings offer both practical guidance and a clearer map of where future work is most urgently needed.

Abstract

Purpose: This study explores how the combination of Problem-Based Learning and Deep Learning pedagogy influences students’ mathematical literacy and disposition, focusing on how both can nurture deeper understanding and sustained engagement. Method: A quasi-experimental approach using a Nonequivalent Pretest–Posttest Control Group design was implemented with 61 participants from MA Mathlaul Anwar Kedondong. The experimental group experienced learning through Problem-Based Learning with Deep Learning principles, while the control group followed conventional instruction. Data from literacy tests, disposition questionnaires, observations, and documentation were analyzed using normality, homogeneity, independent t-tests, and Mann–Whitney procedures. Findings: The integration of the two pedagogical models had a significant impact on mathematical literacy (p = 0.000 < 0.05), reflected in an average N-Gain of 0.57 for the experimental class compared to 0.21 in the control group. Meanwhile, no significant difference was found in students’ mathematical disposition (p = 0.194), although learners in the experimental class demonstrated more stable and constructive attitudes toward mathematics. Significance: Blending Problem-Based Learning with Deep Learning pedagogy effectively enhances mathematical literacy while gradually shaping students’ positive learning attitudes. Continuous and consistent use of this integrative model holds potential for strengthening mathematical disposition in the long term.

Abstract

Purpose: This study to examine the relationship between mathematical disposition and self-concept on elementary students’ mathematical problem-solving ability. The study is based on the assumption that problem-solving requires not only cognitive skills but also affective and psychological factors such as confidence, perseverance, curiosity, and students’ perceptions of their own abilities. Method: This study employed a quantitative ex post facto design involving 54 fifth-grade students selected through saturated sampling. Data were collected using a mathematical problem-solving test and Likert-scale questionnaires measuring mathematical disposition and self-concept. The data were analyzed using multiple linear regression with SPSS 25 to identify the influence of the two affective variables on problem-solving ability. Findings: The analysis showed that mathematical disposition and self-concept have a positive but statistically non-significant relationship with mathematical problem-solving ability. The coefficient of determination (R² = 0.038) indicates that both variables together contribute only 3.8 percent to students’ problem-solving performance, suggesting that other factors outside the study play a much larger role. Significance: The findings indicate that mathematical disposition and self-concept are not significant predictors of elementary students’ problem-solving skills. Other factors such as cognitive strategies, metacognitive skills, motivation, learning environment, and instructional approaches are likely to have greater influence. This highlights the need for future research exploring those variables and developing learning models that integrate affective development with higher-order thinking skills.
