Abstract
Penelitian ini bertujuan untuk mengukur efektivitas penggunaan metode jarimatika dengan bantuan media flashcard dalam meningkatkan hasil belajar matematika pada konsep penjumlahan dan pengurangan siswa kelas II di SDN 24 Temmalebba. Menggunakan metode kuantitatif dengan desain eksperimen semu tipe two group pretest-posttest control group, penelitian ini melibatkan 60 siswa yang terbagi dalam kelas eksperimen (II A) dan kelas kontrol (II B), masing-masing berjumlah 30 siswa. Data dikumpulkan melalui tes pretest dan posttest serta dokumentasi, lalu dianalisis menggunakan statistik deskriptif dan inferensial. Hasil analisis deskriptif menunjukkan peningkatan signifikan pada kelas eksperimen dengan rata-rata nilai pretest 48,67 (tidak tuntas) dan nilai posttest 87,67 (tuntas) setelah intervensi, sedangkan kelas kontrol rata-rata pretest 47,33 dan posttest 81,00. Uji-t inferensial menunjukkan nilai signifikansi < 0,05, menandakan bahwa penggunaan jaritmatika berbantuan flashcard memiliki efektivitas yang signifikan terhadap peningkatan hasil belajar matematika pada konsep penjumlahan dan pengurangan di kelas 2 SDN 24 Temmalebba.
