Abstract

Gender and cultural disparities remain pressing challenges in STEM education across Indonesia’s multi-ethnic regions, particularly in Sundaland, where variations in school accreditation, infrastructure readiness, and mother-tongue use stratify learning opportunities. This study examines differences in scientific literacy and numeracy, focusing on the roles of ethnicity, Socioeconomic Status (SES), and mother-tongue use, while also exploring their interactions with gender and school-level conditions. A quantitative survey design using Hierarchical Linear Modeling (HLM) was applied to capture both student- and school-level variations. Data were collected through literacy tests, questionnaires, and interviews from a stratified sample categorized by accreditation, gender, and SES. The results show that Javanese students achieved the highest scores, while Balinese students obtained the lowest in both competencies, largely reflecting differences in infrastructure and technological support. Male students outperformed in numeracy, whereas females excelled in scientific literacy. Mother-tongue use enhanced conceptual understanding, particularly among Batak and Minangkabau students with strong learning traditions. The implications of this research emphasize the need for inclusive and culturally responsive STEM education policies, which can be achieved by strengthening multilingual education, adopting ethnomathematics approaches, and equalizing school quality to reduce the gap in science literacy and numeracy.

Abstract

This study aims to determine the effect of Team Ganes Tournament (TGT) learning model on students' mathematical communication skills, as well as to identify differences in mathematical communication skills between students taught usingTeam Ganes Tournament (TGT) learning model and students taught without usingTeam Ganes Tournament (TGT) learning model. This research was conducted at La Tansa 2 Junior High School. The research method used was true experimental with pretest-posttestcontrol group design. The research sample consisted of 30 students in the experimental class and 30 students in the control class selected using simple random sampling technique. The instrument used was a description test of 5 questions. The results of this analysis using simple linear regression showed a significance of 0.008, which means there is a significant effect. In addition, the result of t-test with Independent Sample T-Test shows a significance of 0.000, which is smaller than 0.05, so H₀ is rejected and H₁ is accepted. This indicates that there is a significant difference in mathematical communication skills between students taught using theTeam Ganes Tournament (TGT) learning model and students taught using conventional learning

Abstract

This study aims to evaluate the impact of project-based learning (PjBL) in mathematics on the development of 21st-century skills, including critical thinking, communication, collaboration, and creativity. These skills are essential for preparing students to face the challenges of the modern era. However, traditional teaching methods often prove inadequate for optimizing these skills. Utilizing a 3×4 quasi-experimental factorial design, this study involved 90 students, proportionally selected from a population of 872 through random sampling. Data were collected using a learning style questionnaire, observations of teacher instructional methods, and a written test to measure 21st-century skills. Data were analyzed using tests for normality and two-way ANOVA. The results demonstrated that the PjBL approach significantly enhanced students' 21st-century skills (4Cs: Critical Thinking, Collaboration, Communication, Creativity), particularly for those with a kinesthetic learning style and when employing technology-based teaching methods. The interaction between PjBL, students' learning styles, and teachers' instructional methods was found to be effective in fostering the development of these skills, especially in the areas of creativity and problem-solving. This research underscores the importance of innovative approaches in mathematics education to support the development of 21st-century skills.
