Abstract

Sebagai calon guru SD, mahasiswa PGSD dituntut untuk memperoleh keterampilan dalam menyusun perencanaan pembelajaran matematika. Akan tetapi ditemukan masih begitu banyak mahasiswa PGSD yang kurang terampil dalam menyusun perangkat pembelajaran matematika di SD. Penelitian ini bertujuan untuk mendeskripsikan kevalidan, kepraktisan, dan keefektifan bahan ajar perencanaan pembelajaran matematika bagi mahasiwa Tingkat II PGSD. Jenis penelitian ini adalah Research and Development yang mengacu pada model pengembangan dari Plomp dan disederhanakan menjadi emapt fase, yaitu investigasi awal, rancangan, realisasi atau konstruksi, pengujian, dan evaluasi dan revisi. Penelitian ini dilakukan di Unika Santu Paulus Ruteng dengan jumlah subjek penelitian 54 orang. Instrumen penelitian yang digunakan adalah lembar angket dan soal tes. Hasil penelitian menunjukan bahan ajar perencanaan pembelajaran matematika terbukti valid, praktis, dan efektif. Kevalidan didasarkan pada persentase penilaian dari 3 validator, yaitu 87,96% termasuk dalam kategori sangat layak. Kepraktisan didasarkan pada ketuntasan nilai yang diperoleh mahasiswa pada kelas uji coba yang menggunakan bahan ajar tersebut, yaitu nilai minimum 60 dan maksimal 95 sehingga dinilai tuntas dan bahan ajar tersebut praktis. Sedangkan keefektifan didasarkan pada nilai rata-rata kelompok 1 (kelas uji coba) lebih tinggi dari kelompok 2 (kelas kontrol), yaitu 73,14 > 69,74. Dengan demikian, bahan ajar tesebut layak digunakan karena valid, praktis, dan efektif.

Abstract

This research aims to describe creative thinking skills and mathematical problem solving abilities through the application of a project-based learning model. This research uses a quantitative approach with a quasi-experimental method with a posttest-only group design. The sample consisted of 53 students in class V of elementary schools in East Manggarai district which consist two class, with details in the experimental class total 27 people and the control class total 26 people. The sampling technique uses random sampling technique. Data collection techniques use test techniques. The tests used are descriptive tests both to measure creative thinking skills and for data about problem solving abilities. Based on the reliability test results, all items are in the high category. The data analysis technique using MANOVA with the help of SPSS 23.00. The asumtion tests used are data normality test, data homogeneity test, and multicolinearity test. Research findings show that both separately and simultaneously the creative thinking ability and problem solving ability of students who receive learning using the project-based learning model is higher than students who receive learning with conventional models. The project model also has a strong and important impact on the creative thinking abilities and mathematical problem solving abilities of elementary school students. In conclusion, the implementation of the project-based learning model is one of the alternative choices used by teachers for creativity in learning mathematics in elementary schools.

Abstract

Latar Belakang: Pelatihan pemanfaatan media manipulatif kertas lipat dilakukan untuk penguatan kapasitas guru sehingga menghasilkan variasi metode mengajar dan pemilihan media yang relevan.  Tujuan: Program ini bertujuan untuk melatih guru dalam penggunaan media kertas lipat dalam mengkontekstualiasi keabstrakan matematika. Metode: Pelatihan dilaksanakan dengan metode Asset-Based Community Development (ABCD) yang melibatkan empat dosen dan 3 orang guru kelas V SDI Watu Weri. Kegiatan terdiri dari penyampaian teori, implementasi, pendampingan, dan evaluasi implementasi. Hasil: Berdasarkan hasil pengamatan terhadap implementasi dan respons terhadap kegiatan pelatihan menunjukkan bahwa sebesar 91% memberikan respons positif terhadap kegiatan pembelajaran yang diberikan guru sementara untuk keterlaksanaannya mencapai kategori sangat baik.  Kesimpulan: Program PkM ini memberikan dampak positif terhadap peningkatan kapasitas guru dalam mengimplementasikan pembelajaran yang kreatif dan inovatif di kelas.

Abstract

   This qualitative study aims to explore and describe the profile of elementary students' mathematical connection skills in solving numeracy literacy problems contextualized in local wisdom. Conducted from November 2024 to June 2025 at Inpres Mawe Elementary School, Manggarai Timur, the research involved selected fifth-grade students categorized into high, moderate, and low proficiency groups using purposive sampling. Data were collected through written tests and in depth interviews. The written test was designed to assess students’ ability to connect mathematical concepts within real-life and cultural contexts, while interviews were used to further investigate students’ reasoning and understanding. Data validity was ensured through methodological triangulation, comparing written responses with interview results. The data analysis process followed the Miles and Huberman model, consisting of data reduction, data display, and conclusion drawing. Findings reveal notable differences in students' abilities: students with high mathematical connection ability demonstrated good ability to identify, connect, and apply various mathematical concepts in the context of local culture. However, procedural errors were still found in the final calculation stage of problem solving; those at the moderate level showed partial understanding; and low-performing students struggled to relate mathematical concepts to practical or cultural settings. The results underscore the significance of integrating local wisdom into mathematics education to enhance students’ conceptual understanding and numeracy skills. The study recommends instructional approaches that emphasize holistic thinking and the use of diverse representations to strengthen students’ mathematical connections.
