Abstract

Mathematics is considered a difficult subject, leading to boredom and a low understanding of basic mathematical concepts. Difficulty understanding the concepts of LCM and GCF, particularly when working on story problems, is a major obstacle experienced by students. This study aims to identify the development, effectiveness, and practicality of the KOMIKA (Mathematics Mission Box) media in improving understanding of the concepts of LCM and GCF in elementary schools. This study uses the method Research and Development (RnD) by adopting the ADDIE development model. The expert trial involved two parties: two material experts and two media experts. Meanwhile, the product trial involved 31 fifth-grade elementary school students as the main subjects. Data analysis techniques used qualitative and quantitative analysis. The results of the study showed indication that KOMIKA media has proven successful in strengthening conceptual understanding of KPK and FPB at elementary school level. Therefore, it is concluded that the KOMIKA (Mathematics Mission Box) media is valid, effective, and practical to use. The implication of this research is that the development of KOMIKA media as an innovation in learning activities will facilitate students in building and improving their conceptual understanding.

Abstract

Penelitian ini menganalisis dampak model teams games tournament (TGT) yang ditunjang media travel game terhadap pencapaian belajar matematika di tingkat sekolah dasar. Tujuan utamanya adalah untuk mengidentifikasi perbedaan hasil belajar siswa sebelum dan sesudah implementasi serta menilai efektivitas model dan media tersebut. Penelitian ini menerapkan desain pre-eksperimental one group pretest-posttest dengan membandingkan hasil antara pretest dan posttest. Sampel penelitian terdiri dari peserta didik kelas III A SDN 2 Karanggondang. Instrumen penelitian terdiri dari 20 soal telah di uji validitas dan uji reliabilitas yang mendapat nilai Cronbach’s Alpha 0,737 yang mengindikasikan instrumen tersebut valid dan reliabel. Rata-rata pretest adalah 51,25 dan setelah diterapkan perlakuan, rata-rata posttest meningkat menjadi 79,58. Uji statistik t-test sampel berpasangan menghasilkan nilai sig. 0,000 dan nilai t-hitung yang melebihi t-tabel (12.506 > 2.069) menegaskan adanya peningkatan signifikan dalam hasil belajar siswa. Model teams games tournament (TGT) yang dipadukan dengan media permainan perjalanan terbukti berhasil dalam menghasilkan pembelajaran yang menarik dan interaktif. Ini secara substansial meningkatkan pencapaian belajar matematika siswa, terutama pada topik perkalian.
