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

Computational thinking is an essential 21st-century skill that remains low among elementary school students, particularly in Science and Social Studies (IPAS) learning on the topic of changes in the state of matter. This study aims to develop and evaluate the feasibility, practicality, and effectiveness of an educational game entitled The Adventure of Wunda as an interactive learning medium. The research employed a Research and Development (R&D) approach using the ADDIE model, consisting of analysis, design, development, implementation, and evaluation stages. The instruments included expert validation sheets, student response questionnaires, and pre-test and post-test assessments of computational thinking skills. The results showed that the game was valid according to experts, received “practical–very practical” responses from students, and effectively improved computational thinking skills, as indicated by a high N-Gain score and a significant difference based on the Wilcoxon test. Therefore, The Adventure of Wunda is feasible and effective for IPAS learning in elementary schools.

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.

This qualitative study investigates elementary school teachers’ conceptual understanding and instructional strategies for teaching division, with a focus on Bruner’s stages of representation—enactive, iconic, and symbolic. Data were collected from 32 Indonesian teachers through open-ended prompts exploring their interpretations of division and classroom practices. Findings reveal a predominant reliance on procedural models, particularly repeated subtraction, with limited use of conceptual models like equal grouping or inverse multiplication. While many teachers employ concrete strategies, few demonstrate coherent transitions to visual and symbolic representations, resulting in fragmented instruction. The analysis also highlights inconsistencies between teachers' conceptual models and instructional methods, underscoring gaps in pedagogical content knowledge. By integrating frequency tables and case comparisons, the study identifies the need for professional development that supports representational fluency and conceptual alignment. Bruner’s framework is proposed as a guide to scaffold instruction that supports diverse learners and fosters deeper mathematical understanding. Implications for teacher education and curriculum design are discussed.

Latar belakang penelitian ini didasarkan pada rendahnya menulis dan berpikir kritis siswa yang disebabkan oleh penggunaan metode pembelajaran konvensional yang berpusat pada guru dan kurang memberikan ruang bagi siswa untuk mengalami, berefleksi, serta mengaitkan pembelajaran dengan konteks kehidupan nyata. Penelitian ini bertujuan untuk menganalisis pengaruh penerapan model pembelajaran Experiential Learning terhadap keterampilan menulis berpikir kritis siswa sekolah dasar, sekaligus menguji hubungan antara kedua variabel tersebut secara empiris.. Model Experiential Learning, yang menekankan proses belajar melalui pengalaman konkret, refleksi, konseptualisasi, dan eksperimen aktif, diyakini mampu mengatasi permasalahan tersebut dengan menciptakan pembelajaran yang lebih bermakna, partisipatif, dan kontekstual. Penelitian ini menggunakan pendekatan kuantitatif dengan desain quasi experiment tipe Nonequivalent Control Group Design, . Sampel dalam penelitian ini diambil dari SD Santa Ursula Jakarta yang terletak di Kecamatan Sawah Besar, Jakarta Pusat. Data dikumpulkan melalui tes keterampilan menulis narasi dan tes berpikir kritis yang telah diuji validitas dan reliabilitasnya. Analisis data dilakukan menggunakan uji t dan regresi linear sederhana. Hasil penelitian menunjukkan bahwa penerapan model Experiential Learning berpengaruh signifikan terhadap peningkatan keterampilan menulis siswa dengan nilai signifikansi 0,049 (< 0,05) dan terhadap berpikir kritis dengan nilai signifikansi 0,042 (< 0,05). Selain itu, terdapat korelasi positif yang signifikan antara keterampilan menulis dan berpikir kritis dengan nilai signifikansi 0,002 (< 0,05) dan Fhitung sebesar 11,404, yang menunjukkan bahwa semakin baik keterampilan menulis siswa, semakin tinggi pula berpikir kritisnya. Hasil ini menegaskan bahwa penerapan model Experiential Learning efektif dalam mengembangkan dua keterampilan penting tersebut secara bersamaan. Dengan demikian, pembelajaran berbasis pengalaman nyata tidak hanya meningkatkan hasil belajar siswa secara akademis, tetapi juga mengembangkan berpikir tingkat tinggi (Higher Order Thinking Skills), kreativitas, serta kemandirian belajar. Penelitian ini merekomendasikan agar guru menerapkan model Experiential Learning sebagai strategi inovatif dalam pembelajaran Bahasa Indonesia di sekolah dasar, karena model ini selaras dengan semangat Kurikulum Merdeka.
