Abstract

This study investigated the effectiveness of a Think-Talk-Write (TTW) strategy integrated with GeoGebra in promoting mathematical communication ability and collaborative learning among Grade X secondary school students. Employing a quasi-experimental design with a non-equivalent control group, the study involved 34 students in the experimental group (TTW-GeoGebra) and 32 students in the control group (conventional instruction) at SMA Negeri 3 Tanjung Raja during the 2025/2026 academic year. Data were collected using a 10-item mathematical communication test and a 15-item collaboration questionnaire, both of which demonstrated good reliability (α = 0.883 and α = 0.866, respectively). Results indicated that the TTW-GeoGebra model produced a moderate improvement in mathematical communication (n-gain = 0.59) and a high improvement in collaborative learning (n-gain = 0.75) in the experimental group, both significantly exceeding the control group’s gains (p < 0.001). Between-group comparisons confirmed that the TTW-GeoGebra model was significantly more effective than conventional instruction for both outcomes. These findings suggest that embedding GeoGebra as a didactic medium across all TTW phases constitutes a principled instructional design for simultaneously developing mathematical communication and collaboration, consistent with NCTM’s process standards and Indonesia’s Kurikulum Merdeka.

Abstract

This study developed and evaluated a trigonometry teaching module grounded in Project-Based Learning (PjBL) integrated with local wisdom from Merangin Regency, Indonesia, using the ADDIE development model. Needs analysis across three state senior secondary schools revealed that 80.2% of students found trigonometry difficult and 71.1% perceived mathematics as disconnected from daily life. The module, designed for tenth-grade students (Phase E) and aligned with Indonesia’s Merdeka Belajar curriculum, embedded the six-step PjBL syntax within contextual activities centred on the Tugu Pedang and Jam Gento—culturally iconic landmarks in Merangin Regency. Expert validation by three mathematics teachers yielded an overall feasibility score of 4.47 (89.49%), placing the module in the Very Feasible category. Practicality testing during a small-group trial (two teachers; ten students) indicated Very Practical ratings from teachers and Practical to Very Practical ratings from students across all assessed aspects. Large-group effectiveness testing employed a quasi-experimental non-equivalent comparison group design (n = 35 per class). The experimental class achieved a mean posttest Higher Order Thinking Skills (HOTS) score of 83.69 versus 65.45 in the control class, with classical mastery rates of 91.43% and 2.86% respectively. An independent-sample t-test confirmed a significant difference (Sig. = 0.000 < 0.05). These findings establish that the developed module is valid, practical, and effective, offering a replicable model for contextualising abstract mathematics through local cultural integration within project-based instructional frameworks. These findings are theoretically grounded in Project-Based Learning theory (Thomas, 2000) and Bloom’s revised taxonomy for HOTS (Anderson & Krathwohl, 2001), and are directed at tenth-grade (Phase E) students within Indonesia’s Merdeka Belajar curriculum framework.

Abstract

This study analyses how the STEAM+X framework has been implemented in mathematics education. The “X” component represents additional disciplines beyond the traditional STEAM fields, such as culture, history, and architecture. The systematic literature review (SLR) follows the PRISMA protocol. The initial search returned 350,190 documents, but only one article met the rigorous inclusion criteria focused explicitly on STEAM+X in mathematics education. This finding underscores the topic’s novelty and the need for further research. The selected study highlights the integration of geometry, digital and physical technologies (e.g., GeoGebra, AR/VR, 3D printing), and educational levels, including high school and teacher education. The analysis reveals limited implementation across countries and a lack of diversity in content areas. These results call for expanded investigations into STEAM+X practices incorporating broader mathematical domains, varied cultural contexts, and more inclusive educational levels.

Abstract

Despite decades of curriculum reform, persistent gaps in Indonesian mathematics education remain. Students are taught mathematics formally, yet consistently fail to demonstrate higher-order reasoning abilities. Both national and international assessments confirm that mathematical critical thinking skills encompassing the ability to evaluate arguments, investigate claims, and draw logical conclusions remain a critical weakness, particularly at the junior high school level. This situation is further compounded by the minimal use of digital technologies such as GeoGebra and Scratch in everyday classroom instruction. This study conducted a preliminary investigation into the mathematical critical thinking abilities and mathematics learning experiences of Grade VIII students in Cirebon Regency (West Java) and Pamekasan Regency (East Java), serving as the empirical foundation for the development of the FJIMEC (Focusing, Justifying, Investigating, Messaging, Evaluating, Concluding) instructional model integrated with GeoGebra and Scratch. Using a convergent parallel mixed-methods design, the study involved 128 students and four mathematics teachers. The critical thinking test results were concerning: mean scores of 41.2 for Cirebon and 39.8 for Pamekasan, with 84.4% of students falling in the low category. The weakest indicators were Evaluating and Concluding. The Mann-Whitney U test revealed no significant between-region difference (p = 0.412), indicating a systemic deficit. Questionnaire analysis revealed low technology utilization (M = 2.43/5.00) and high mathematics anxiety. These findings provide preliminary empirical support for developing a FJIMEC–GeoGebra–Scratch instructional model.

Abstract

Mathematical communication ability and learning independence are essential 21st-century competencies that remain underdeveloped in vocational mathematics education, where students often perceive mathematics as irrelevant to their careers. This quasi-experimental study investigated the effectiveness of integrating the Learning Cycle 6E model with Dynamic Geometry Software (GeoGebra) in improving these competencies among vocational high school students. Sixty-nine tenth-grade students from the Marketing Skills Program were assigned to experimental (n=35) and control (n=34) groups through random sampling. The experimental group received instruction using the six-phase Learning Cycle 6E model (engage, explore, explain, elaborate, evaluate, extend) integrated with GeoGebra, while the control group received conventional expository instruction. Data were collected through mathematical communication tests and learning independence questionnaires administered as pretest and posttest. Normalized gain (N-Gain) analysis was employed to measure improvement effectiveness. Results demonstrated that the experimental group achieved significantly higher improvement in mathematical communication ability (N-Gain = 0.62) compared to the control group (N-Gain = 0.44), representing a 40.9% advantage. Similarly, learning independence improved significantly more in the experimental group (N-Gain = 0.51) versus the control group (N-Gain = 0.26), nearly doubling the control group's gain. Statistical analyses confirmed both differences were significant (p < 0.05) with large effect sizes. These findings provide empirical evidence that integrating constructivist pedagogy with dynamic technology effectively enhances both cognitive and metacognitive competencies in vocational mathematics education, offering a practical framework for revitalizing mathematics instruction to meet contemporary educational demands and career-relevant applications.

Abstract

The integration of technology into mathematics instruction is increasingly acknowledged as a means to foster 21st-century competencies, particularly mathematical communication and independent learning. This study investigates the effects of the 6E instructional model combined with Dynamic Geometry Software (DGS) on these two aspects. A quasi-experimental design was conducted with tenth-grade students from a vocational school in Sukoharjo, Central Java. The sample included 35 students in the experimental group and 34 students in the control group, selected randomly. Mathematical communication was measured using essay-based pre- and post-tests, while learning autonomy was assessed through questionnaires administered before and after the intervention. Normality and homogeneity tests using Kolmogorov–Smirnov and Levene’s confirmed the assumptions for parametric analysis. Data were analyzed using the Independent Sample T-test. Results indicated that significance values for both mathematical communication and learning autonomy were below 0.05, showing statistically significant differences between groups. The experimental group achieved an average post-test score of 82.40, higher than the control group’s 74.24, indicating improved mathematical communication under the 6E model with DGS integration. Similarly, the experimental group’s average final questionnaire score of 105.11 exceeded the control group’s 90.38, reflecting greater learning autonomy. These findings demonstrate that embedding GeoGebra within the 6E instructional model substantially enhances students’ ability to articulate mathematical ideas and promotes independent learning. The study provides empirical support for technology-enhanced learning designs in mathematics education, highlighting their potential to strengthen key competencies and contribute to more effective instructional practices.

Abstract

This study examines how a design-based implementation research (DBIR) approach can accelerate developmentally appropriate digitalization in early childhood education within a rural village ecosystem. We co-designed, piloted, and iteratively refined a practice-proximal package, professional learning and coaching, a contextualized digital lesson bank, implementation tools (rubrics/SOPs), and organizational supports, delivered through a stepped-wedge rollout across six ECE centers (310 children; 34 staff). Mixed methods integrated repeated surveys/logs, structured classroom observations and artefact audits, and interviews/FGDs; instruments covered teacher outcomes, classroom processes, center-level implementation outcomes, and system supports. Quantitatively (n=18 teachers), teachers strongly endorsed play-based pedagogy and age-appropriate management and reported high confidence to blend traditional–digital approaches, while routine device/app use and simple media creation were lower, indicating an enactment fluency gap. Qualitatively, key barriers were limited devices/media, uneven digital skills, and device-related classroom management; children’s engagement was predominantly positive. Triangulation suggests two proximal mechanisms, motivation and procedural clarity, by which coaching and SOPs (rotation/transition) convert enthusiasm into on-task behavior. Findings yield a feasible pathway for scale: prioritize shared-device solutions and offlineable media, intensify practice-based coaching on two workflow “kernels,” and institutionalize leadership-backed routines. Future work will test dose–response and moderation using longitudinal mixed-effects models and center-level interrupted time series to assess sustainment and generalizability.

Abstract

This research aims to identify and reveal the connection between ethnomathematics and ethnomodeling in Indonesia’s bocah sukerta traditional ceremony. An ethnographic design was used to reveal the research objectives. The participants involved in this research were the ceremony leader and bocah sukerta. Next, the data obtained from interviews and observations were analyzed using the content analysis method. The research results reveal that the ethnomathematics connection is reflected in weighting activities (weighing objects, calculating total weight, making comparisons, and balancing weights) and the shape of the scales (the basic shape represents 2D geometry, and the frame shape represents 3D geometry). This research also concludes that the ethnomodeling connection produces mathematical understanding, especially in arithmetic operations, weight measurements, weight conversions, mathematical equations, basic statistics, Cartesian coordinates, the center point of a square, and determining a pyramid’s distance, length, and area. Furthermore, this research concludes that the relationship between ethnomathematics and ethnomodeling in the bocah sukerta traditional ceremony can be used to construct didactic designs for square material volumes and rectangular pyramids.

Abstract

Mathematical story problems present persistent challenges for students worldwide, yet little research explores how students with low conceptual understanding subjectively experience these difficulties. This phenomenological study investigated the lived experiences of 15 Indonesian Grade VIII students (ages 13-15) with low conceptual understanding in mathematical story problem-solving. Using open-ended questionnaires and reflexive thematic analysis, we explored students’ perceptions and challenges in a private junior high school in West Lombok Regency, Indonesia. Three interconnected themes emerged: (1) Internal Psychological Barriers—mathematics anxiety, fixed mindset beliefs, and internalized failure attributions; (2) Cognitive and Linguistic Challenges—difficulties in text comprehension, mathematical representation, strategic knowledge, and multi-step reasoning; and (3) Glimpses of Interest—unexpected positive affective responses to story contexts despite struggles. Findings reveal that low conceptual understanding is not a unitary cognitive deficit but a complex, multi-dimensional phenomenon involving cognitive, affective, linguistic, and motivational dimensions. Students experience multiple, compounding obstacles while carrying emotional burdens that further impede learning. By centering student voice, this study illuminates subjective realities that quantitative achievement data alone cannot capture. Implications suggest effective interventions must comprehensively address conceptual skills, affective barriers, linguistic demands, and motivation simultaneously. For Indonesian contexts, findings call for reconsidering traditional approaches prioritizing procedural fluency over conceptual understanding and student wellbeing. This research advances phenomenological methodology in mathematics education and provides actionable insights for developing responsive, equity-oriented instruction.

Abstract

Mathematical connection ability remains a persistent weakness among Indonesian junior secondary students, with diagnostic data from SMP Negeri 2 Kaloran, Temanggung Regency, Indonesia showing that 74–81% of Grade 7 students failed to meet minimum competency on ratio and proportion across two academic years. Compounding this problem, classroom observations indicated chronically low learning motivation among the same cohort. This study examined whether contextual learning integrated with gamification (CTL+Gamification), delivered through the Wayground platform, could address both deficits simultaneously. A quasi-experimental design with nonequivalent control groups was employed, involving 56 Grade 7 students (experimental n = 27; control n = 29) selected through multi-stage cluster random sampling in Temanggung Regency. The experimental group received six sessions embedding ratio and proportion content in locally meaningful contexts, tobacco farming, coffee yield, and map scale, while the control group received conventional expository instruction. Mathematical connection ability was assessed using a validated seven-item essay test (Aiken’s V = 0.83; α = 0.84), and learning motivation using a 25-item ARCS-based questionnaire (α = 0.87). Independent-sample t-tests and two-way ANOVA revealed that the experimental group significantly outperformed the control group in mathematical connection ability (t = 3.542, p = .001, d = 0.97) and learning motivation (t = 2.201, p = .032, d = 0.59), while the instructional model × motivational level interaction was nonsignificant (F = 1.306, p = .280). These findings suggest that contextually grounded, gamified instruction can strengthen both cognitive and affective outcomes, offering a locally adaptable model for mathematics teaching under Kurikulum Merdeka.
