Abstract

Indonesian students’ low statistical literacy, as revealed by PISA 2022 with only 18% achieving Mathematics competency at level 2, presents an urgent educational challenge. The dominant use of printed teaching materials limits students’ digital learning experiences with varying levels of initial understanding. This study developed differentiated E-LKPD (Electronic Student Worksheets) using Liveworksheets on Data Presentation topics through Research and Development with ADDIE model. Participants were 7th grade students of SMP Gunungjati 1 Purwokerto in the 2024/2025 academic year. Data collection instruments included interview instruments, needs analysis questionnaires, validation questionnaires, student response questionnaires, and statistical literacy tests. The product achieved very high validity based on Aiken’s index for content (0.91), media (0.94), and language (0.90). Practicality received 86% with very practical criteria. The product’s effectiveness showed statistical literacy improvement with N-Gain of 0.60 (moderate). The differentiated E-LKPD using Liveworksheets proved valid, practical, and effective in enhancing statistical literacy skills of junior high school students. This digital, interactive approach successfully accommodates diverse student readiness levels, providing an innovative solution for personalized mathematics learning that bridges the gap between traditional instruction and students’ digital learning needs.

Abstract

Background: Critical thinking skills are essential in addressing the learning challenges faced by students in the 21st century. To foster these skills effectively, it is necessary to adopt specific instructional approaches that enhance students’ mathematical critical thinking within the classroom setting.Aims: This study aims to investigate students’ critical thinking abilities in mathematics during the implementation of the Argumentation-Based Learning Process (ABLP) in classroom instruction.Methods: A qualitative case study design was employed, involving 30 eighth-grade students from an A-accredited school in Indonesia. Data sources included ABLP-based worksheets, audio recordings of student group discussions, and interview transcripts. The collected data were analyzed using a triangulation strategy to ensure accuracy, and peer reviews were conducted to validate the findings. The analysis focused on identifying indicators of critical thinking skills at each stage of the ABLP model.Results: The results show that students demonstrated various levels of critical thinking throughout the ABLP stages. However, not all students consistently met the predetermined indicators at each stage of the process. Despite these variations, the findings suggest that ABLP can be an effective pedagogical approach to foster students’ critical thinking in mathematics.Conclusion: This study concludes that ABLP offers meaningful opportunities for students to develop critical mathematical thinking and should be considered as a strategy in mathematics instruction.

Abstract

Background: Although three-dimensional (3D) geometry is an essential component of the elementary school mathematics curriculum, research exploring how students develop spatial understanding of 3D geometric objects in authentic learning contexts remains limited. Furthermore, the challenge of bridging visual, verbal, and manipulative representations persists as a major gap in the literature.Aims: This study aims to address this gap by examining the process through which elementary students develop conceptual understanding of 3D geometry using a grounded theory approach.Method: The study was conducted at a public elementary school in Indramayu Regency, West Java, Indonesia. A total of 26 students (20 female and 6 male, aged 11–12) voluntarily participated. Data were collected through 3D geometric visualization tests and in-depth interviews focusing on students' thought processes in imagining, comparing, and manipulating spatial forms. Data analysis followed the three stages of grounded theory methodology: open coding, axial coding, and selective coding, to construct a theory grounded in empirical data.Results: The findings reveal that students’ understanding of 3D volume is still in a transitional stage, moving from concrete experiences to formal mathematical representations. Familiar local contexts alone were found insufficient to bridge spatial understanding without adequate visual and pedagogical support. Major obstacles included conceptual misconceptions, procedural errors, limited visualization skills, and reliance on teacher assistance.Conclusion: The core category, “multiple representations as a bridge to spatial understanding,” underscores the importance of integrating concrete visualization, verbal description, and mathematical symbolism in geometry instruction. This study suggests that teachers should design instructional strategies that systematically combine visual media, concrete manipulatives, and verbal approaches. Such integration is crucial to ensure that local contexts effectively serve as a bridge between real-world experiences and abstract mathematical understanding.

Abstract

Background: Geometry plays a fundamental role in mathematics education by developing logical reasoning and spatial understanding. Despite its importance, geometry remains a difficult subject for university students, particularly in distance learning contexts. While several studies have analyzed geometry textbooks, few have examined their knowledge structures through a praxeological perspective. Aim: This study aims to analyze a university-level Euclidean geometry textbook by identifying how the components of praxeology, namely task (T), technique (τ), technology (θ), and theory (Θ), are organized and interconnected to support meaningful learning. Method: The research applied a hermeneutic phenomenological design. The textbook, used in a master’s geometry course at an Indonesian university, was analyzed through repeated readings and qualitative interpretation. Data were coded and categorized according to the praxeological framework and validated through researcher discussions. Result: The findings show that the textbook demonstrates a coherent praxeological structure with accurate theoretical explanations and effective technological representations. However, the analysis revealed weaknesses such as limited rationale for applying specific techniques, insufficient connection between theoretical concepts and exercises, and few examples of proofs. Conclusion: The study concludes that while the textbook reflects strong praxeological principles, improvements are needed in clarifying technique rationales, linking theory and practice, and structuring technological components. The results provide pedagogical insights for developing university geometry textbooks that enhance conceptual understanding, reflective reasoning, and learning effectiveness in both traditional and distance education settings.

Abstract

Students’ mathematical visual-spatial ability is a key component in understanding geometry, and students need to master this skill. However, the level of students' mathematical visual-spatial ability is less than optimal, so quality learning is necessary. The purpose of this study was to test the quality of the Geogebra-assisted 6E-Instructional Model (6E-IM) on students' spatial visual ability; test the effect of Geogebra-assisted 6E-IM on spatial visual ability; and describe students' spatial visual ability after receiving the Geogebra-assisted 6E-IM model. This study used an embedded design. The independent variable in this study was the Geogebra-assisted 6E-IM, and the dependent variable was spatial visual ability. The variables of the 6E-IM learning model assisted by Geogebra were measured using interviews, while visual spatial abilities were measured using questionnaires. The results showed that the geometry learning instrument with the 6E-IM learning model assisted by Geogebra was in the very good category with a score of 92%. The 6E-IM learning model assisted by Geogebra had a positive effect on students' visual spatial abilities.. Description of students' spatial visual ability involving 2 students in each category, in the high category, met all indicators of spatial visual ability; students with moderate spatial visual ability met two indicators of spatial visual ability; and students with low spatial visual ability met one indicator of spatial visual ability. The results of this study are expected to be Geogebra integrated 6E-IM Design can be used by teachers to improve students' visual spatial abilities.

Abstract

Purpose: This study aims to examine how successful mathematics learning is constructed through the dynamic interaction of affective dispositions, cognitive-metacognitive strategies, socio-pedagogical scaffolding, resilience, and epistemological flexibility within post-pandemic online learning environments. Method: An intensive single-case study design was employed, utilizing in-depth interviews with a student and three mathematics teachers as the primary data collection instrument. Data were systematically analyzed through open, axial, and selective coding procedures adapted from grounded theory. Findings: Four interrelated conceptual models emerged from the analysis: (1) the Ecosystemic Formation of Sustainable Learning Identity, (2) the Adaptive Academic Reconstitution Model, (3) Learning Ecosystem Support as an Adaptive Developmental System, and (4) the Adaptive Transitional Learning Ecosystem Model. Collectively, these models reconceptualize mathematical success not as a discrete performance outcome, but as an ecosystemic and developmentally sequenced achievement requiring coherent integration of internal identity formation, strategic regulatory capacity, and adaptive ecosystem support. Significance: These findings carry substantial implications for the development of post-pandemic pedagogical frameworks, advocating for holistic and identity-constitutive approaches that extend beyond mere content remediation in online mathematics education.

Abstract

Background: Students in distance statistics courses often achieve lower learning outcomes compared to those in face-to-face settings. Although the Technological Pedagogical Content Knowledge (TPACK) framework has been widely applied in technology-integrated instruction, limited empirical evidence clarifies whether prior mathematical knowledge (PMK) moderates its effectiveness in asynchronous online statistics learning. Aim: This study examined the effectiveness of a TPACK-based online tutorial design in improving students’ statistical literacy and investigated the moderating role of PMK. Methods: A quasi-experimental design involved 170 distance education students (experimental n = 85; control n = 85) classified into low, medium, and high PMK levels. The experimental group participated in a 12-session TPACK-based online tutorial with periodic webinar integration, while the control group received conventional online instruction. Statistical literacy was measured using post-test and normalized gain scores and analyzed through two-way ANOVA and simple effects tests. Results: The analysis revealed a significant main effect of tutorial design (ηp² = .102–.116), indicating higher achievement among students receiving TPACK-based instruction. PMK showed a stronger main effect (ηp² = .215–.230), suggesting substantial differences in performance across readiness levels. A significant interaction effect demonstrated a threshold pattern. Students with medium and high PMK obtained significantly higher post-test scores and normalized gains in the experimental group, while students with low PMK showed no statistically significant differences between tutorial designs. The magnitude of learning gains increased consistently from low to high PMK categories, confirming that instructional benefits intensified alongside mathematical readiness. Conclusion: The effectiveness of TPACK-based online tutorials depends on students’ prior mathematical knowledge. Instructional advantages are pronounced for learners with adequate foundational skills but limited for those with low readiness. These findings emphasize the need for adaptive support mechanisms to ensure that technology-integrated instruction produces equitable outcomes in distance statistics education.

Abstract

Purpose: This study aims to examine the effects of a TPACK-informed online tutorial design on self-regulated learning (SRL) achievement and improvement among graduate distance education students, while investigating whether prior mathematical knowledge (PMK) moderates those effects. Method: A quasi-experimental non-equivalent control group design was employed with 170 graduate students (experimental: n = 85; control: n = 85) enrolled in the Educational Statistics course (MPDR5202) at Universitas Terbuka. SRL was measured using a 37-item questionnaire across six dimensions (maximum score = 148). Data were analyzed using non-parametric statistics, specifically the Mann-Whitney U test and Kruskal-Wallis test. Findings: The TPACK-based tutorial design was associated with significantly higher SRL achievement (Z = −2.971, p = .003) and greater SRL improvement (Z = −4.807, p < .001) compared to the conventional tutorial design, though causal attribution is limited by the quasi-experimental design.PMK level alone did not produce a significant main effect on either SRL outcome. However, an omnibus rank-difference test across condition-by-PMK cells yielded a significant result (H = 25.762, p < .001), with post-hoc comparisons suggesting that students with medium and high PMK showed greater SRL improvement under TPACK-based instruction, while the pattern for low PMK students was inconclusive given the small subgroup size (n = 10). This interaction pattern should be regarded as preliminary. Significance: This study provides preliminary empirical support for the role of intentional, technology-integrated instructional design, specifically TPACK-informed online tutorials, in fostering self-regulated learning (SRL) in distance higher education, although causal conclusions remain limited by the quasi-experimental design. The finding that PMK appears to moderate the impact on SRL improvement suggests practical implications for instructional designers and distance educators. A uniform TPACK approach may be insufficient for students with low prior knowledge, pointing to the potential value of differentiated scaffolding strategies. However, this interaction pattern warrants replication in larger and more balanced samples before firm recommendations can be made.
