Abstract

Penelitian ini bertujuan meningkatkan kemampuan pemahaman konsep bilangan, menulis lambang bilangan, mencocokkan jumlah gambar dengan lambang bilangan, dan mencocokkan lambang bilangan dengan jumlah gambar. Penelitian menggunakan metode Penelitian Tindakan Kelas (PTK) model Kemmis dan McTaggart dalam dua siklus, dengan tiap siklus meliputi perencanaan, tindakan, observasi, dan refleksi. Subjek penelitian adalah lima siswa hambatan intelektual sedang kelas XI. Data dikumpulkan melalui tes, observasi, wawancara, dan dokumentasi, lalu dianalisis secara kuantitatif dan kualitatif. Secara kuantitatif dengan persentase dan kualitatif melalui reduksi data, penyajian data, serta penarikan kesimpulan. Hasil belajar menunjukkan peningkatan kemampuan pemahaman konsep bilangan. Secara kuantitatif, rata-rata kemampuan awal siswa sebesar 39,99% meningkat menjadi 73,33% pada Siklus I dan 93,33% pada Siklus II, sehingga seluruh siswa memenuhi KPM sebesar 70%. Secara kualitatif, guru dan siswa awalnya beradaptasi karena metode dan media ini tergolong baru, namun siswa berangsur menjadi lebih aktif, percaya diri, dan mandiri, bahkan menunjukkan antusiasme dan kegembiraan saat berhasil menyelesaikan tugas, sementara guru semakin terampil menyederhanakan instruksi, memberi pendampingan individual, dan penguatan positif secara konsisten. Dengan demikian, media POKATIF melalui metode bermain edukatif terbukti dapat meningkatkan pemahaman konsep bilangan pada siswa hambatan intelektual sedang kelas XI. ***** This study aims to improve the ability to understand number concepts, specifically writing numerals, matching the number of pictures with numerals, and matching numerals with the number of pictures. The study employed the Classroom Action Research (CAR) method based on the Kemmis and McTaggart model, conducted in two cycles, with each cycle consisting of planning, action, observation, and reflection. The research subjects were five students with moderate intellectual disabilities in grade XI. Data were collected through tests, observation, interviews, and documentation, then analyzed both quantitatively and qualitatively. The quantitative analysis was carried out using percentages, while the qualitative analysis was conducted through data reduction, data display, and conclusion drawing. The learning outcomes showed an improvement in students' understanding of number concepts. Quantitatively, the students' average initial ability of 39.99% increased to 73.33% in Cycle I and 93.33% in Cycle II, meaning all students met the minimum mastery criterion of 70%. Qualitatively, both the teacher and students initially had to adapt since the method and media were new; however, the students gradually became more active, confident, and independent, even showing enthusiasm and joy upon successfully completing tasks, while the teacher became increasingly skilled at simplifying instructions, providing individual guidance, and consistently giving positive reinforcement. Thus, the POKATIF media through the educational play method proved effective in improving the understanding of number concepts among grade XI students with moderate intellectual disabilities.
