Hasil capaian dalam pelajaran IPS khususnya pada siswa kelas 4 SD N Baran masih rendah. Tujuan penelitian ini adalah untuk mendeskripsikan peningkatan hasil belajar IPS melalui pembelajaran kooperatif tipe NHT pada siswa kelas 4 SD N Baran. Penelitian ini merupakan Penelitian Tindakan Kelas. Objek penelitian adalah siswa kelas 4 SD N Baran yang berjumlah 9 orang. Pendekatan penelitian menggunakan pendekatan kualitatif. Metode tes dan non tes berupa observasi digunakan sebagai metode pengumpulan data. Metode analisis data yang digunakan adalah metode kuantitatif dan kualitatif. Penelitian dilaksanakan dalam 2 siklus. Hasil penelitian menunjukkan bahwa rata-rata nilai tes meningkat setiap siklusnya. Pada pra tindakan hasil rata-rata 51,79 meningkat menjadi 12,30 menjadi 64 pada siklus I, dan pada siklus II mean 81 meningkat 17. Pada pra tindakan mencapai 0% meningkat 11% menjadi 22 % pada Siklus I. Pada Siklus II ketuntasan meningkat sebesar 67%, sehingga pencapaian ketuntasan siswa pada Siklus II mencapai 89%. Artinya hasil belajar IPS meningkat dari Siklus I hingga akhir Siklus II. Dapat dikatakan bahwa penerapan model pembelajaran kooperatif tipe NHT dapat meningkatkan hasil belajar siswa. The learning achievement in Social Studies, particularly among Grade 4 students at SD N Baran, is still low.
