Abstract
Pengembangan Bahan Ajar Kimia Materi Stoikiometri Kelas X Berbasis Masalah di SMA N 3 Palembang. Pengembangan Bahan Ajar kimia Materi Stoikiometri Kelas X Berbasis Masalah di SMA N 3 Palembang telah diujicobakan di kelas X Mia 2 SMA N 3 Palembang. Bahan Ajar yang Valid, Praktis dan Efektif menggunakan model pengembangan Rowntree dan evaluasi formatif Tessmer. Tahap Expert Review diperoleh rata-rata skor 4,16. Tahap one-to-one dan small group diperoleh skor 4,51. Dan berdasarkan tes hasil belajar siswa yaitu kelas ujicoba dan kelas biasa, nilai pretest kelas uji coba 22,14. nilai pretest kelas biasa 21,85 sedangkan nilai post test kelas uji coba yaitu 91, 14. dan nilai post test kelas biasa 79,42. Data tersebut menunjukkan hasil belajar siswa yang menggunakan Bahan Ajar Kimia Materi Stoikiometri Kelas X Berbasis Masalah lebih baik dari pada hasil belajar siswa yang tidak menggunakan Bahan ajar Kimia Materi Stoikiometri Kelas X Berbasis Masalah. dari data diatas dapat disimpulkan bahwa Bahan ajar kimia Materi Stoikiometri Kelas X Berbasis Masalah dinyatakan Valid, Praktis dan Efektif. Saran peneliti bagi guru untuk dapat mengembangkan dan menggunakan bahan ajar kimia Materi Stoikiometri Kelas X Berbasis Masalah.
