Abstract
ABSTRAK: Penelitian ini bertujuan untuk memperoleh deskripsi tentang penerapan model Problem Based Learning dalam meningkatkan hasil belajar siswa pada materi aritmatika sosial di Kelas VII D SMP Negeri 19 Palu. Jenis penelitian ini yaitu Penelitian Tindakan Kelas (PTK) dengan mengacu pada desain penelitian Kemmis dan Mc. Taggart, yaitu 1) perencanaan, 2) pelaksanaan tindakan, 3) observasi, dan 4) refleksi. Penelitian ini dilaksanakan dalam dua siklus. Subjek penelitian adalah siswa kelas VII D SMP Negeri 19 Palu yang terdaftar pada tahun ajaran 2018/2019 sebanyak 30 siswa, 19 siswa perempuan dan 11 siswa laki-laki.
