Abstract

Penelitian pengembangan ini didasari oleh permasalahan dalam pembelajaran matematika, khususnya pada materi perkalian bilangan cacah di sekolah dasar, yang masih mengalami kendala karena kurangnya penggunaan media konkret. Untuk mengatasi permasalahan tersebut, penelitian ini mengembangkan alat peraga Kalimatika yang bertujuan membantu siswa memahami konsep perkalian. Tujuan penelitian ini yaitu untuk mengetahui proses pengembangan alat peraga Kalimatika, mengetahui kelayakan alat peraga Kalimatika, serta mengukur efektivitas alat peraga Kalimatika, dan mengetahui respons guru serta siswa terhadap alat peraga Kalimatika. Penelitian ini menggunakan metode Research and Development (R&D) dengan model pengembangan ADDIE (Analysis, Design, Development, Implementation, Evaluation). Tahapan penelitian meliputi analisis kebutuhan, karakteristik siswa, dan lingkungan belajar, desain dan instrumen penelitian, pengembangan media dan validasi oleh ahli, implementasi pada siswa serta evaluasi hasil implementasi. Teknik pengumpulan data dilakukan melalui wawancara, angket, dan soal tes. Partisipan penelitian melibatkan ahli materi, ahli media, guru, dan siswa kelas III. Instrumen penelitian berupa lembar validasi ahli materi, lembar validasi ahli media, angket respons guru, angket respons siswa, dan soal tes pretest dan posttest. Hasil penelitian menunjukkan bahwa media Kalimatika layak digunakan berdasarkan hasil validasi dari ahli media sebesar 94,7% dan ahli materi sebesar 98,6% yang termasuk kategori “Sangat Layak”. Hasil uji efektivitas melalui uji N-Gain menunjukkan peningkatan pemahaman siswa sebesar 0,59 dengan kategori “sedang”. Alat peraga Kalimatika juga mendapat respons sangat baik dari guru dan siswa. This development research was motivated by problems in mathematics learning, particularly in the topic of whole number multiplication in elementary schools, which still faces challenges due to the lack of concrete media use. To address this issue, this study developed a learning aid called Kalimatika, aimed at helping students understand the concept of multiplication. The objectives of this study are to explore the development process of the Kalimatika learning aid, assess its feasibility, measure its effectiveness, and examine teacher and student responses to the media. This study employed the Research and Development (R&D) method using the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The stages of the research included needs analysis, student characteristics, and learning environment; design and research instruments; media development and expert validation; implementation with students; and evaluation of the implementation results. Data collection techniques included interviews, questionnaires, and test items. The research participants consisted of material experts, media experts, teachers, and third-grade students. Research instruments included material expert validation sheets, media expert validation sheets, teacher response questionnaires, student response questionnaires, and pretest-posttest items. The results showed that the Kalimatika media was deemed highly feasible, with validation scores of 94.7% from media experts and 98.6% from material experts, both falling into the "Highly Feasible" category. The effectiveness test using the N-Gain formula indicated an increase in student understanding by 0.59, which is categorized as "moderate." In addition, Kalimatika received highly positive responses from both teachers and students.
