Meningkatkan Hasil Belajar Matematika Materi Kecepatan Menggunakan Model Cooperative Tipe Grup Investigation

This research was conducted to improve student learning outcomes in the subject of speed mathematics using the Cooperative Type Group Investigation model in class VB MI NW Kalijaga. This type of research is Classroom Action Research (CAR) using quantitative methods, because this data uses numbers, starting from data collection, data interpretation and appearance of results. as many as 14 students. The results of this study can be seen from student learning outcomes, in the pre-cycle there are still many students who have not completed based on KBM (73%), in the pre-cycle there are only five students who have completed (35.7%) with an average score of 56, 8, the highest score was 93 and the lowest score was 30. In the first cycle there was an increase to seven students (50%) who completed KBM, the average value was 63.2, the highest score was 95 and the lowest score was 30. In the second cycle of learning improvement from The 14 students who completed KBM increased again to 10 students (89%), the average score was 75.6, the highest score was 98 and the lowest score was 40.Penelitian ini dilakukan untuk meningkatkan hasil belajar siswa pada mata pelajaran Matematika materi kecepatan menggunakan model Cooperative Tipe Grup Investigationdi kelas VB MI NW Kalijaga. Jenis penelitian ini yaitu Penelitian Tindakan Kelas (PTK) dengan menggunakan metode kuantitatif, karena data ini menggunakan angka, mulai dari pengumpulan data, penafsiran data dan penampilan hasil.Subjek penelitian adalah siswa kelas V MI NW Kalijaga dan sampel sampel penelitian kelas VB MI NW Kalijaga sebanyak 14 siswa.Hasil penelitian ini terlihat dari hasil belajar siswa, pada prasiklus masih banyaknya siswa yang belum tuntas berdasarkan KBM (73%), pada pra siklus hanya ada lima siswa yang tuntas (35,7%) dengan nilai rata – rata 56,8, nilai tertinggi 93 dan nilai terendah 30.Pada siklus satu ada peningkatan menjadi tujuh orang siswa siswa (50%) yang tuntas KBM, nilai rata-rata 63,2, nilai tertinggi 95 dan nilai terendah 30. Pada perbaikan pembelajaran siklus dua dari 14 siswa yang tuntas KBM meningkat lagi menjadi 10 siswa (89%), nilai rata-rata 75,6, nilai tertinggi 98 dan nilai terendah 40
