kemampuan berpikir kritis, hasil belajar, laju reaksi, model PBLAbstract
Penelitian ini bertujuaan untuk (1) meningkatan aktivitas guru, (2) meningkatan aktivitas peserta didik, (3) meningkatan kemampuan berpikir kritis, (4) meningkatan hasil belajar aspek sikap, keterampilan, dan pengetahuan peserta didik. Jenis penelitian ini yaitu penelitian tindakan kelas (PTK) yang terdiri dari 2 siklus. Subjek penelitian adalah murid kelas XI SMAN 8 Banjarmasin dengan jumlah 27 siswa. Instrumen penelitian berupa tes dan non tes. Analisis data menggunakan teknik analisis kualitatif dan kuantitatif. Hasil penelitian menunjukkan (1) terjadi peningkatan aktivitas guru dari kategori baik menjadi kategori sangat baik (2) terjadi peningkatan aktivitas peserta didik dari kategori cukup menjadi kategori aktif, (3) terjadi peningkatan kemampuan berpikir kritis siswa dari kategori kurang kritis menjadi kategori kritis (4) terjadi peningkatan hasil belajar sebesar 76% (tuntas), terjadi peningkatan hasil belajar aspek sikap pesreta didik dari predikat baik menjadi sangat baik, aspek keterampilan peserta didik mengalami peningkatan dari predikat cukup menjadi baik, dan aspek pengetahuan mengalami peningkatan ketuntasan secara klasikal sebanyak 89%.
