Pelajaran matematika sering dianggap sulit oleh siswa, yang berdampak pada minat siswa yang rendah dan kemampuan berpikir kreatif matematis yang belum optimal. Salah satu faktor penyebabnya adalah media pembelajaran yang kurang interaktif. Penelitian ini bertujuan untuk mengembangkan media pembelajaran interaktif berbantuan Canva untuk meningkatkan kemampuan berpikir kreatif matematis siswa SMP pada materi aljabar dan menguji kevalidan media, mengetahui kepraktisan penggunaan media, serta peningkatan kemampuan berpikir kreatif matematis siswa. Media pembelajaran interaktif yang dikembangkan berfokus pada empat indikator berpikir kreatif: (1) Kelancaran, yaitu kemampuan memberikan ide atau jawaban yang benar, menuliskan diketahui dan ditanyakan, serta menyelesaikan soal dengan tepat; (2) Fleksibilitas, yaitu Kemampuan menyelesaikan masalah dengan dua/lebih cara namun memiliki jawaban yang tunggal dan benar; (3) Orisinalitas, yaitu kemampuan menyelesaikan soal dengan cara mereka sendiri yang unik dan tidak biasa; dan (4) Keterincian, yaitu kemampuan menyusun ide atau jawaban secara rinci. Metode penelitian yang digunakan adalah R&D (Research and Development) dengan model ADDIE (Analyze, Design, Development, Implementation, Evaluation). Penelitian ini dilaksanakan di SMP Negeri 1 Ciniru pada kelas VII C dengan jumlah 30 siswa. Data yang digunakan dalam penelitian meliputi wawancara dengan guru matematika, angket analisis kebutuhan siswa, soal tes berdasarkan indikator kemampuan berpikir kreatif, serta penilaian kepraktisan dari guru dan siswa. Instrumen yang digunakan berupa angket dan soal tes kemampuan berpikir kreatif. Pengujian kevalidan media dilakukan setelah pengembangan media selesai, sedangkan analisis kepraktisan dilakukan setelah proses pembelajaran. Peningkatan kemampuan berpikir kreatif diukur melalui pretest dan posttest. Kevalidan media pembelajaran berdasarkan penilaian dua validator ahli materi sebesar 77% dalam kategori "valid". Kevalidan berdasarkan penilaian dua validator ahli media sebesar 86% dalam kategori "sangat valid". Kepraktisan media pembelajaran berdasarkan penilaian siswa diperoleh nilai sebesar 84%, dan berdasarkan penilaian guru diperoleh nilai sebesar 97%, keduanya dalam kategori "sangat praktis". Pengujian peningkatan kemampuan berpikir kreatif matematis siswa menunjukkan rata-rata nilai pretest 17,17 dan posttest 75,83, dengan analisis N-gain score menghasilkan rata-rata 0,72 dalam kategori "tinggi". Media pembelajaran interaktif berbantuan Canva terbukti dapat meningkatkan kemampuan berpikir kreatif matematis siswa SMP pada materi aljabar.

Mathematics lessons are often considered difficult by students, which has an impact on low student interest and suboptimal mathematical creative thinking skills. One of the contributing factors is less interactive learning media. This study aims to develop interactive learning media assisted by Canva to improve junior high school students' mathematical creative thinking skills in algebra material and test the validity of the media, determine the practicality of using the media, and improve students' mathematical creative thinking skills. The interactive learning media developed focuses on four indicators of creative thinking: (1) Fluency, namely the ability to provide correct ideas or answers, write known and asked, and solve problems correctly; (2) Flexibility, namely the ability to solve problems in two or more ways but have a single and correct answer; (3) Originality, namely the ability to solve problems in their own unique and unusual way; and (4) Detail, namely the ability to organize ideas or answers in detail. The research method used is R&D (Research and Development) with the ADDIE model (Analyze, Design, Development, Implementation, Evaluation). This research was conducted at SMP Negeri 1 Ciniru in class VII C with 30 students. The data used in the study included interviews with mathematics teachers, student needs analysis questionnaires, test questions based on indicators of creative thinking skills, and practicality assessments from teachers and students. The instruments used were questionnaires and creative thinking skills test questions. Media validity testing was carried out after media development was completed, while practicality analysis was carried out after the learning process. The increase in creative thinking skills was measured through pretest and posttest. The validity of the learning media based on the assessment of two material expert validators was 77% in the "valid" category. The validity based on the assessment of two media expert validators was 86% in the "very valid" category. The practicality of the learning media based on student assessments obtained a value of 84%, and based on teacher assessments obtained a value of 97%, both in the "very practical" category. Testing the increase in students' mathematical creative thinking skills showed an average pretest score of 17.17 and a posttest of 75.83, with the N-gain score analysis producing an average of 0.72 in the "high" category. Interactive learning media assisted by Canva has been proven to improve junior high school students' mathematical creative thinking skills in algebra material.
