Pengembangan Media Komik Berbasis Model Pembelajaran Kooperatif Tipe Stad Pada Mata Pelajaran Matematika Materi KPK Dan FPB Kelas Iv Di Min 1 Mojokerto

Mathematics instruction in elementary schools still frequently relies on textbooks and worksheets with only text and formulas, without narrative illustration, which easily bores fourth-grade students when studying Least Common Multiple (LCM) and Greatest Common Factor (GCF) materials. This study aims to develop a comic-based learning medium based on the Student Teams Achievement Division (STAD) cooperative learning model that is valid and receives a positive response from fourth-grade students at MIN 1 Mojokerto. The study used a Research and Development (R&D) approach based on the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The trial subjects were students in classes IV A and IV B at MIN 1 Mojokerto, and the instruments included validation sheets for material experts, media experts, classroom teachers, and a Likert-scale student response questionnaire. The results show that the comic medium obtained an average score of 3.8 from the material expert (very valid, 76%), 3.1 from the media expert (valid, 62%), and 4.7 from the fourth-grade teacher (very valid, 94%). Student responses reached 86% in the product trial and 88% in the usage trial, both categorized as good. These findings confirm that an illustrated comic medium with a narrative storyline can serve as a feasible and appealing alternative mathematics learning medium for fourth-grade elementary school students.
