Abstract

This study aims to improve the ability of multiplication arithmetic operations through the application of Jarimatika techniques. Classroom action research  implemented collaborative classroom teachers in two cycles. The subject of research grade II SD N 100070 Lobulayan T.A 2014 amounted to 22 students. Data collection techniques: tests, observation, interviews and documentation. Descriptive data analysis techniques. The result increased the percentage of the total value and average grade. In the first cycle of meeting one class average 64.09 (50%) and the second meeting of the average grade 69.27 (68.18%). First cycle first meeting an average grade 77.59 (81.81%) and the second meeting of the average grade 81.77 (86.36%).

Abstract

Penelitian ini bertujuan untuk meningkatkan kemampuan operasi hitung perkalian melalui penerapan teknik jarimatika. PTK dilaksanakan secara kolaboratif bersama guru kelas dalam dua siklus. Subjek penelitian siswa kelas II SD N 100070 Lobulayan T.A 2014 berjumlah 22 siswa. Teknik pengumpulan data: tes, observasi, wawancara dan dokumentasi. Teknik analisis data deskriptif. Hasilnya meningkat dari persentase jumlah nilai dan rata-rata kelas. Pada siklus I pertemuan 1 rata-rata kelas 64,09 (50%) dan pertemuan 2 rata-rata kelas 69,27 (68,18%). Siklus II pertemuan 1 rata-rata kelas 77,59 (81,81%) dan pertemuan 2 rata-rata kelas 81,77(86,36%). Kata Kunci: teknik jarimatika, operasi hitung perkalian¸penelitian tindakan kelas.
