Abstract
Penelitian ini bertujuan untuk mengetahui minat dan ketuntasan belajar siswa pada materi Reaksi Redoks dan Sel Elektrokimia melalui penerapan model pembelajaran Discovery Learning. Penelitian ini merupakan penelitian tindakan kelas (Action Research Classroom) yang dilaksanakan dengan dua siklus. Setiap siklus terdiri dari perencanaan, pelaksanaan tindakan, observasi dan refleksi. Subyek penelitian ini adalah siswa kelas XII-IPA-3 SMA Negeri 6 Madiun tahun pelajaran 2019-2020..
