Berdasarkan kajian literatur yang telah dilakukan, PBL merupakan salah satu model pembelajaran yang mampu membuat aktivitas belajar lebih aktif sehingga berpengaruh positif pada motivasi belajar dan pemahaman konsep peserta didik. Tujuan penelitian ini adalah untuk meningkatkan motivasi belajar peserta didik melalui model pembelajaran Problem Based Learning (PBL) pada mata pelajaran Ekonomi kelas VII SMP Negeri 4 Kairatu. Penelitian ini menggunakan Metode Penelitian Tindakan Kelas (Classroom Action Research).Penelitian dilaksanakan dengan kolaborasi antara peneliti,guru dan melibatkan keaktifan peserta didik . Subjek penelitian peserta didik siklus 1 dan siklus 2. Yang menjadi populasi adalah semua peserta didik kelas 7 SMP Negeri 4 Kairatu sebanyak 28 siswa, sampelnya diambil dari keseluruhan populasi. Teknik pengumpulan data menggunakan observasi dan angket sederhana. Prosedur penelitian meliputi tahap : (a) perencanaan tindakan, (b) pelaksanaan tindakan ,(c) observasi dan intrepretasi, dan (d) analisis dan refleksi. Dari penelitian terhadap aspek-aspek tersebut, maka dapat di simpulkan bahwa Model pembelajaran Problem Based Learning (PBL) dapat meningkatkan motivasi belajar peserta didik sebesar 10,54% (siklus I sebesar 79,92% dan Siklus II sebesar 90,4%). Peningkatan keaktifan peserta didik dalam pembelajaran sebesar 19,36 % (siklus I sebesar 75,02% dan Siklus 2 sebesar 93,10%.Kesimpulan Hipotesis dapat diterima.
