摘要：Penelitian ini bertujuan untuk mendeskripsikan hasil belajar siswa SMA Negeri 12 Semarang pada materi protista akibat penerapan model pembelajaran learning cycle. Penelitian pre-experimental design dengan pretest and posttest group design telah dilaksanakan pada kelas X-8 dan X-9. Data utama berupa data hasil belajar yang diperoleh dengan teknik tes dan non tes. Data pendukung terdiri dari data aktivitas siswa dan kinerja guru yang diperoleh dengan metode observasi,serta tanggapan siswa yang diperoleh dengan metode angket. Data dianalisis dengan uji N-gain.
