Abstract
Penelitian ini dilatarbelakangi oleh rendahnya kemampuan pemahaman konsep matematis peserta didik terhadap materi nilai tempat bilangan ratusan. Salah satu penyebabnya yaitu kurangnya penggunaan media pembelajaran, sehingga peserta didik kesulitan dalam memahami konsep dasar matematika. Penelitian ini bertujuan untuk mengembangkan media pembelajaran interaktif Berlian berbasis Comprehensive Mathematics Instruction (CMI) untuk meningkatkan kemampuan pemahaman konsep matematis peserta didik kelas 3 Sekolah Dasar. Metode yang digunakan adalah Design and Development (D&D) dengan model ADDIE (analysis, design, development, implementation, dan evaluation). Teknik pengumpulan data meliputi lembar validasi ahli, angket respon peserta didik, serta soal pre-test dan post-test. Adapun subjek dari penelitian ini adalah 20 peserta didik fase B kelas 3 pada salah satu Sekolah Dasar di Kabupaten Bandung Barat. Media pembelajaran ini dinilai kelayakannya oleh empat ahli yaitu ahli materi, ahli media, ahli bahasa, dan praktisi pembelajaran. Hasil dari validasi ahli materi memperoleh hasil 98,21%. Hasil dari validasi ahli media memperoleh hasil 98,21%. Perolehan hasil validasi bahasa yaitu 80,76%, serta hasil dari praktisi pembelajaran memperoleh presentase 98%. Uji coba produk menunjukkan pengingkatan kemampuan pemahaman konsep peserta didik dengan perolehan skor N-Gain sebesar 0,69 yang termasuk kategori sedang. Dengan demikian, media pembelajaran interaktif Berlian dinyatakan layak untuk digunakan dan efektif dalam meningkatkan pemahaman konsep nilai tempat bilangan ratusan pada peserta didik fase B Sekolah Dasar. This research is motivated by the low ability of students to understand mathematical concepts regarding the material of place value of hundreds. One of the causes is the lack of use of learning media, so that students have difficulty in understanding basic mathematical concepts. This study aims to develop interactive learning media Berlian based on Comprehensive Mathematics Instruction (CMI) to improve the ability to understand mathematical concepts of 3rd grade elementary school students. The method used is Design and Development (D&D) with the ADDIE model (analysis, design, development, implementation, and evaluation). Data collection techniques include expert validation sheets, student response questionnaires, and pre-test and post-test questions. The subjects of this study were 20 phase B students of grade 3 at an elementary school in West Bandung Regency. The feasibility of this learning media was assessed by four experts, namely material experts, media experts, language experts, and learning practitioners. The results of the material expert validation obtained a result of 98.21%. The results of the media expert validation obtained a result of 98.21%. The results of the language validation obtained a percentage of 80.76%, and the results of the learning practitioners obtained a percentage of 98%. The product trial showed an increase in students' conceptual understanding, with an N-Gain score of 0.69, which is considered moderate. Therefore, the Berlian interactive learning media is deemed suitable for use and effective in improving students' understanding of the place value concept of hundreds in Phase B Elementary School.
