The capacity for mathematical reasoning, pivotal in grasping core math concepts, directly shapes a student's success in their mathematical studies. This study aimed to detail and analyze how the search, solve, create, and share (SSCS) instructional framework impacts mathematical reasoning skills within the context of linear equations. We adopted a quasi-experimental research approach using a non-matching control group design. To gather data on mathematical reasoning proficiency, a validated and reliable essay-type test was employed. Data collection on mathematical reasoning abilities used an essay test instrument that has been valid and is reliable. This research involved 102 eighth grade students whereby they were selected by using a purposive sampling. o measure and describe the effect size, we utilized a specific method, yielding a result of 0.97. The t-test was employed to assess the influence of the SSCS learning model, and the significance value obtained was less than 0.05. The effect size, as determined, stands at 0.97, suggesting a substantial impact. The t-test results underscore a significant relationship between the SSCS learning model and the enhancement of mathematical reasoning abilities. This research delineates a framework for employing the SSCS model to enhance students' mathematical reasoning capabilities. It is evident that such reasoning abilities play a pivotal.

Higher Order Thinking Skills (HOTS) are high-level thinking skills that include analytical, evaluative, and creative abilities. HOTS is essential in 21st-century education, where students are expected not only to recall information but also to think critically and creatively in facing various challenges. This study aims to determine the improvement of students' HOTS through the application of the Bridging Analogy learning model. The research design employed a quasi-experimental approach with one experimental class and one control class. The instruments used in this study were a HOTS test for Matrix material and a student learning activity questionnaire. Research data were analyzed using statistical analysis with SPSS. The ANCOVA results showed that the Bridging Analogy learning model significantly influenced students' HOTS. The data analysis also revealed that the average HOTS score of students in the experimental class (84.73) was higher than that of the control class, which used conventional learning (55). These findings indicate that the implementation of the Bridging Analogy learning model effectively enhances students' HOTS compared to conventional learning. This research contributes to the development of innovative learning models that support the improvement of students' higher-order thinking skills in mathematics education.

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.

This study aimed to scrutinize the effectiveness of the DMR (Diskursus Multy Reprecentacy) model with Question Box media in bolstering the mathematical representation abilities of eighth-grade students. A quasi-experimental design was employed, engaging 96 students selected via Cluster Random Sampling technique. The effectiveness was evaluated by comparing the DMR model against the conventional expository teaching method using a t-test with a 5% significance level. In this research, data testing uses the SPSS application. Findings revealed that the DMR teaching model assisted by the Question Box media was significantly more effective in enhancing students' mathematical representation skills than the traditional expository model. These findings suggest that the integration of the DMR teaching model with Question Box media could serve as an alternative pedagogical strategy in mathematics education to facilitate a deeper understanding of mathematical concepts among students.

Evaluating students' mathematical communication ability is crucial for understanding their ability to convey mathematical ideas logically, precisely, and in a structured manner. A good evaluation instrument is the primary tool for measuring this aspect objectively and purposefully. This research is motivated by the low mathematical literacy achievement of Indonesian students in the 2018 PISA survey, which indicates weak mathematical communication ability. This study aims to analyze students' mathematical communication ability from a gender perspective. This study used a quantitative method with a survey design. The survey type used was a cross-sectional survey design. The results showed that female students had higher average scores than male students, but the ANOVA test produced a significance value of 0.621 (> 0.05), indicating no significant difference. This finding shows that mathematical communication ability is more influenced by individual factors. The implication is that teachers need to use adaptive learning approaches and evaluation instruments that address individual student needs.

Purpose – Advancements in digital learning require students to be adequately prepared both psychologically and technologically. However, students’ attitudes toward digital learning have not yet been systematically mapped using data-driven segmentation approaches. This study aims to classify university students based on similarities in their attitudes toward digital learning using the K-Means clustering algorithm and to identify the most influential dimensions distinguishing levels of digital readiness.Methods – This study employed an exploratory quantitative design using survey data collected from 469 university students. Clustering was conducted using the K-Means algorithm implemented in the Orange Data Mining application. Two variable schemes were compared: a limited scheme comprising four constructs (Psychological Traits, Growth Mindset, Learner Motivation & Engagement, and Digital Competence) and a full scheme including six constructs with the addition of Digital Readiness & Mindfulness and Student Satisfaction. Data were normalized using Min–Max normalization, and cluster quality was evaluated using the Silhouette Coefficient.Findings – Results indicate that both schemes consistently produced two optimal clusters representing students with high and low levels of digital learning readiness. The highest Silhouette Coefficient values were obtained at K = 2 for both schemes (0.335 for the limited scheme and 0.323 for the full scheme). Psychological Traits and Learner Motivation & Engagement emerged as the most significant differentiating dimensions between clusters, followed by Digital Competence.Research limitations – The findings are limited to self-reported data and a single institutional context, which may constrain generalizability. Additionally, the cross-sectional design does not capture changes in student attitudes over time.Originality – This study contributes a comparative clustering framework that integrates psychological, motivational, and technological dimensions to map digital learning readiness. The results provide a practical foundation for designing adaptive and personalized digital learning strategies based on student readiness profiles.
