Abstract

This study aims to analyze the role of extracurricular activities in developing self-efficacy among elementary school children through a systematic literature review. The objective is to explore how participation in various extracurricular programs enhances students' academic, social, and emotional competencies, with the hypothesis that extracurricular engagement positively correlates with higher self-efficacy. A total of 25 peer-reviewed journal articles published between 2013 and 2023 were selected through database searches using keywords related to self-efficacy, extracurricular activities, and elementary education. Studies involved children aged 6–12 years from diverse geographic and demographic contexts. Thematic synthesis was employed to identify key patterns and findings. The results indicate that involvement in activities such as sports, arts, music, and scouting significantly contributes to the development of self-efficacy through mastery experiences, vicarious learning, and social support from peers and mentors. Furthermore, the findings confirm the initial hypothesis, showing a reciprocal relationship between extracurricular participation and self-efficacy—each reinforcing the other. A unique contribution of this study lies in its focus on elementary-aged children and its implications for educational practices in the Indonesian context. These findings imply that schools should intentionally design and implement extracurricular programs to support students' personal growth and psychological well-being. Future research is encouraged to examine moderating variables, such as gender, socio-economic background, and type of activity, that may influence the strength of these relationships.

Abstract

This study explores the integration of Ethnomathematics within the Zero Waste cultural framework, grounded in Education for Sustainable Development (ESD), to enhance students' creative thinking skills and sustainability awareness. Conducted in several elementary and middle schools in Surabaya, Indonesia, the research employed an Inquiry-Based Learning (IBL) model combined with cognitive, affective, and behavioral questionnaires and tests. The findings indicate that embedding local cultural elements in mathematics learning significantly improves students' understanding of sustainable practices, particularly in waste management, recycling, and resource planning. Observations revealed that students demonstrated greater enthusiasm, creativity, and critical thinking when engaging with mathematical concepts contextualized in real-world environmental issues. Additionally, the application of Zero Waste principles in traditional market settings allowed students to connect mathematical theories such as geometry, data analysis, and spatial planning to everyday sustainability challenges. The study concludes that the ethnomathematics approach not only fosters academic achievement but also cultivates responsible environmental behavior. However, the scope was limited to specific cultural and geographic contexts, suggesting the need for further research across diverse settings. This research contributes to the growing body of knowledge emphasizing the importance of culturally responsive pedagogy in sustainability education and recommends expanding such models to broader educational environments.

Abstract

This study explores the potential of Augmented Reality (AR)-based learning media integrated with ethnomathematics to enhance students’ spatial ability in the context of teaching 3D geometry to fifth-grade elementary students. Spatial ability, which includes spatial perception, mental rotation, spatial visualization, spatial relations, and spatial orientation, is a critical cognitive skill for understanding geometric concepts. A Systematic Literature Review (SLR) method was employed to identify, evaluate, and synthesize findings from 15 studies related to the use of AR and ethnomathematics in mathematics education. The review reveals that AR offers significant advantages in presenting three-dimensional geometric objects interactively, visually, and concretely, which improves students' comprehension of abstract spatial relationships and enhances mental manipulation of objects. Additionally, the integration of ethnomathematics provides contextual learning experiences by linking mathematical content to students’ cultural backgrounds, thereby increasing engagement and motivation. These findings support the Van Hiele theory, emphasizing the importance of gradual stages in geometric understanding. The combination of AR and ethnomathematics not only deepens spatial reasoning but also promotes meaningful and culturally relevant learning experiences. Future studies should further explore the impact of AR-based ethnomathematical media through empirical classroom-based research and assess its long-term effects on students’ mathematical thinking and spatial abilities. The 21 students selected for the classroom trials were chosen through purposive sampling, ensuring the sample’s relevance to the study context.

Abstract

The aim of this research was to analyze initial needs in developing concrete learning media in the form of Ribeka Rings to improve numeracy understanding and environmental awareness for fifth grade of elementary school students. The condition of the school environment was not kept clean and the students' low awareness of waste management can be overcome through the integration of numeracy learning with the use of recycled waste as a concrete medium. Environmental awareness that is formed through the use of recycled waste as a learning medium can be strengthened with a collaborative approach, where teachers, students and the community jointly design and create ribeka ring media in order to increase students' understanding of numeracy and environmental awareness in the school. The method used in this research is a descriptive approach with data collection techniques through observation, interviews and questionnaires for teachers and students. The research results show that students need learning media that can visualize mathematical concepts in a concrete and fun way. These findings supported the development of Ribeka Ring media as an effective means of increasing understanding of numeracy while instilling environmental awareness in elementary school students. Learning media that combines mathematical concepts with environmental awareness, such as the Ribeka Ring, can be an effective solution for improving students' understanding of numeracy and environmental awareness simultaneously. It is hoped that this media can make learning more fun and relevant to real life.
