Matematika adalah mata pelajaran yang umum dipelajari oleh siswa di sekolah dasar, sekolah menengah, dan perguruan tinggi. Namun, matematika tetap dianggap sebagai pelajaran yang sulit bagi siswa. Studi ini menyelidiki bagaimana permainan tradisional New Damdaman berbasis etnomatematika dapat meningkatkan pemahaman matematis siswa. Keterampilan matematika awal (KAM) siswa dinilai dari tiga sudut pandang (tinggi, sedang, dan rendah). Pengujian juga dilakukan untuk mengetahui bagaimana kemampuan pemahaman dan efikasi diri matematis berhubungan satu sama lain. Studi ini menggunakan desain eksperimen semu, yang melibatkan dua desain kelompok: satu untuk kelompok eksperimen dan satu lagi untuk kelompok kontrol. Siswa SMP kelas VIII di SMP N 3 Kalimanah adalah subjek penelitian. Uji hipotesis menggunakan ANOVA, uji t-independent, dan korelasi. Hasil penelitian menunjukkan bahwa siswa yang dididik melalui pendekatan berbasis etnomatematika yang menggunakan permainan tradisional New Damdaman lebih memahami konsep matematika dibandingkan dengan siswa di kelas kontrol yang diajarkan metode konvensional. Dilihat dari kategori kemampuan awal matematika, terlihat bahwa siswa yang menggunakan pembelajaran berbasis etnomatematika dan permainan tradisional New Damdaman meningkatkan pemahaman mereka tentang konsep matematika. Pembelajaran berbasis etnomatematika dan pembelajaran konvensional memiliki tingkat efikasi diri matematis yang berbeda. Siswa memiliki korelasi yang positif antara pemahaman mereka tentang konsep matematis dan tingkat efikasi diri mereka. Kata kunci: pembelajaran berbasis etnomatematika, pemahaman konsep matematis, permainan New dam-daman, efikasi diri matematis

This research is motivated by the low mathematical problem-solving ability of elementary school students, especially when facing non-routine problems that require complex reasoning. The integration of Realistic Mathematics Education (RME) and Computational Thinking (CT) is seen as an approach capable of presenting contextual learning while stimulating systematic thinking processes. This research uses a quantitative method with a Quasi-Experimental Non-Equivalent Control Group Design involving fifth-grade students from two elementary schools in Prambon District. The experimental group received RME learning integrated with CT, while the control group received direct learning. Data were collected through pre-tests, post-tests, and self-efficacy questionnaires, then analyzed using a two-way ANOVA to examine the effect of the learning model, self-efficacy, and the interaction between the two. The results showed that the RME-CT model significantly improved mathematical problem-solving ability compared to conventional learning, with higher score increases in the experimental group. In addition, self-efficacy was shown to moderate learning effectiveness, where students with high self-efficacy achieved better results. There was a significant interaction between learning models and self-efficacy on learning outcomes. This research contributes to offering an innovative approach that combines realistic contexts and computational thinking as an effective strategy to improve elementary school students' mathematical competence and self-confidence.

This study analyzes strategies to reconstruct learning experiences in elementary schools, focusing on character development and the Pancasila Student Profile Strengthening Project (P5) to mitigate learning loss. Conducted in Bogor, Jakarta, and Banyumas, this research used a phenomenological approach to explore participants' lived experiences, aligning with the study’s focus on personal insights into learning loss impacts. Purposive sampling selected participants, including teachers, principals, and two students from each of five schools, chosen for their direct engagement in character education and P5 activities. Data were collected via interviews, observations, and documentation, with credibility validated through triangulation. Findings reveal that learning loss impacts are significant and multifaceted, including declines in motivation, increased learning disparities, dropout risks, delays in reading, and decreases in academic performance and character. Effective character development was identified as involving positive reinforcement, a character-centered school culture, teacher modeling, and habitual practices. The P5 project, implemented through a project-based learning model, effectively integrated Pancasila values, fostering essential character traits such as perseverance, hard work, and adaptability alongside academic skills. The results highlight the P5 project's role in addressing learning loss by enhancing both academic and character growth. This approach provides practical insights for schools aiming to strengthen student resilience and adaptability. The study concludes that character development and P5 implementation can effectively reconstruct learning experiences in elementary education, supporting both academic recovery and character formation. These findings offer implications for educators and policymakers seeking comprehensive strategies to address learning loss in Indonesian schools.

Contemporary perspectives on 21st-century education emphasize that primary schooling must cultivate transferable competencies that extend beyond content mastery. In Indonesia, the implementation of the 2023 Curriculum and the Merdeka Belajar framework foregrounds Deep Learning (Pembelajaran Mendalam) as a means to achieve the 6Cs (i.e., character, citizenship, collaboration, communication, creativity, and critical thinking) from the earliest grades. This study reports a community service (Pengabdian Kepada Masyarakat, PKM) intervention designed to strengthen primary teachers’ capacity to understand and implement this policy in their classrooms. The program involved 28 teachers from SD Negeri Pondok Cabe Ilir 02, Tangerang Selatan, and adopted a four-stage model: observation, socialization, workshop and mentoring, and evaluation. A mixed-methods approach was employed, incorporating teacher surveys on knowledge and self-efficacy, classroom observations aligned with the 6Cs, analysis of lesson plans and student artifacts, and focus group discussions. Data were analyzed using descriptive statistics, inferential tests, and thematic analysis. The findings reveal significant improvements in teachers’ knowledge, understanding, and awareness of Deep Learning, which fostered a collective commitment to redesign lessons and adopt more active, student-centered pedagogies. Teachers applied differentiated strategies across grade levels: story- and play-based learning in lower grades, and guided inquiry in both middle and upper grades. The program also encouraged professional collaboration and mentoring, although barriers such as limited preparation time, insufficient resources, and varied levels of teacher readiness persisted. These results suggest that the implementation of Deep Learning in primary schools requires sustained and context-sensitive professional development, supportive school leadership, adequate resources, and longitudinal research to link changes in teacher practice with long-term improvements in student learning outcomes.

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.
