Abstract

study aims to examine the effectiveness of teaching materials ‘Misi BangDat’ based on Problem-Based Learning (PBL) in improving the understanding of mathematical concepts of elementary school students on the material of flat buildings. The research design used pre-experimental method with one-group pretest-posttest. The research sample consisted of 24 grade II students in one of the elementary schools in West Bandung Regency. The results showed an increase in the average score of students' understanding of mathematical concepts from 57.29 (pretest) to 82.29 (posttest). N-Gain analysis showed a score of 80.87%, which is in the high category, proving that this teaching material is effective. The implementation of PBL-based teaching materials helps students understand concepts interactively and contextually, improve critical thinking skills, and facilitate understanding of abstract mathematics material. This study recommends the use of ‘Misi BangDat’ teaching materials as an innovative solution to improve mathematics learning at the primary school level.

Abstract

This study aims to develop teaching materials to improve students’ conceptual understanding of fractions. The research employed a Design and Development method using the ADDIE model, which consists of five stages: analysis, design, development, implementation, and evaluation. The data obtained were both qualitative and quantitative. Qualitative data were collected from expert validators’ suggestions, while quantitative data were derived from validators’ assessments and student test results. The research subjects were 17 fourth-grade elementary school students in Bandung. The findings revealed that the teaching material RIHAN achieved a feasibility score of 90.3% from material, language, and design experts, and 92.5% from teacher practitioners, categorized as highly feasible. Furthermore, the effectiveness test showed an N-gain score of 0.533 (moderate category), indicating an improvement in students’ conceptual understanding. Therefore, the RIHAN teaching material is considered feasible and effective for enhancing elementary school students’ conceptual understanding of fractions.

Abstract

This study addresses the persistent challenge of limited procedural understanding in multiplication among elementary school students in Indonesia, particularly those in Phase B. Many students struggle to follow correct steps, select appropriate strategies, and apply multiplication concepts to real-life contexts—issues often exacerbated by traditional teaching methods that prioritize rote memorization over active, tangible learning experiences. The study aims to examine the effectiveness of the GASING method in enhancing procedural understanding of multiplication among fourth-grade students. Employing a pre-experimental one-group pre-test and post-test design, the study involved 24 purposively selected students. Data were collected using pre- and post-test instruments and analyzed through the Wilcoxon test. Results indicate a significant improvement in students' procedural understanding following the intervention, with a p-value of 0.001, demonstrating statistical significance at the 0.05 level. The findings affirm that the GASING method—characterized by its concrete, visual, and interactive learning approach—effectively strengthens students’ procedural skills in mathematics. This research contributes to the growing literature on innovative teaching methods in mathematics education and provides practical guidance for educators seeking to implement engaging, structured instructional strategies.

Abstract

Rendahnya kemampuan pemahaman konsep matematis siswa menunjukkan urgensi penerapan pembelajaran berbasis RME yang berpusat kepada siswa dan bertitik tolak dari kehidupan nyata. Tujuan penelitian ini untuk menganalisis efektivitas pendekatan RME terhadap peningkatan kemampuan pemahaman konsep matematis siswa kelas IV pada materi membandingkan dan mengurutkan pecahan berpembilang satu. Penelitian ini menggunakan metode kuantitatif dengan desain pre-experimental bentuk one-group pretest-posttest design dan teknik purposive sampling. Teknik pengumpulan data menggunakan tes (pretest dan posttest) serta data dianalisis menggunakan uji non-parametrik, berupa uji wilcoxon dan uji perbedaan terhadap skor n-gain. Hasil penelitian dengan bantuan SPSS Statistics 26 diperoleh bahwa nilai signifikansi sebesar 0,000 < 0,05 dan skor n-gain sebesar 0,83 atau 83,01% sehingga dapat disimpulkan bahwa pendekatan RME efektif untuk meningkatkan kemampuan pemahaman konsep matematis siswa kelas IV pada materi membandingkan dan mengurutkan pecahan berpembilang satu.

Abstract

Permasalahan yang melatarbelakangi penelitian ini yaitu belum optimalnya kemampuan peserta didik dalam memecahkan masalah matematis yang disebabkan oleh pemilihan model pembelajaran serta media yang belum sepenuhnya memfasilitasi untuk mengembangkan kemampuan penyelesaian masalah. Penelitian ini bertujuan untuk memperoleh gambaran tingkat efektivitas model Laps-Heuristic berbantuan media Flashcard dalam meningkatkan kemampuan penyelesaian masalah matematis pada peserta didik kelas V pada materi keliling persegi dan persegi panjang. Penelitian ini menggunakan metode Pre-Experimental dengan desain One Group Pretest-Posttest. Sampel yang digunakan yaitu peserta didik kelas V di salah satu SD Negeri Kota Bandung berjumlah 24 orang. Teknik dalam pengumpulan data terdiri dari tes berupa soal uraian non-rutin sebanyak 5 soal dan observasi. Analisis data yang dilakukan yaitu melalui statistik deskriptif dan inferensial. Berdasarkan temuan penelitian, disimpulkan bahwa model Laps-Heuristic berbantuan media Flashcard cukup efektif dalam meningkatkan kemampuan penyelesaian masalah matematis peserta didik kelas V. Hal ini dibuktikan dengan skor N-Gain sebesar 0,63 termasuk pada kategori sedang dan persentase N-Gain sebesar 63,07% menunjukkan kategori cukup efektif.
