Peningkatan Prestasi Belajar Biologi Menggunakan Model Pembelajaran Investigasi

This research is aimed to analyze: (1) lesson plan design (RPP) of Group Investigation Model, (2) implementing of Group Investigation Model; (3) evaluation system of Group Investigation Model of learning; (4) increasing student achievement using Group Investigation Model. The method of the research is Classroom Action Research (CAR) through three cycles. The result of the research could be concluded as (1) lesson plan design (RPP) using Group Investigation Model including making group, delivering, accessing, completing materials, discussion and presentation, reorganizing, classroom discussion and presentation and evaluating, (2) implementation of Group Investigation Model can develop student activities. The student activities of XI Science 1 in the first cycle is 77.16%, in the second cycle is 82.83% and in the third cycle is 90.19%, Class XI Science-2 in the first cycle is 77.16%, in the second is 82.00%, and in the third is 88.34%, (3) the student achievement is increasing. In XI Science-1, the students got minimum mastery criteria (KKM) in the first cycle were 14 (46.67%), in second were 19 (63.33%) and in the third were 23 (76.67%).Penelitian ini bertujuan untuk menganalisis: (1) desain RPP, (2) pelaksanaan pembelajaran, (3) sistem evaluasi, (4) peningkatan prestasi belajar Biologi menggunakan Model Investigasi Kelompok. Metode Penelitian yang digunakan adalah Penelitian Tindakan Kelas dengan tiga siklus. Hasil penelitian dapat disimpulkan: (1) desain RPP dengan Model Investigasi Kelompok meliputi pembagian kelompok, materi, mengakses, melengkapi materi, diskusi dan presentasi, pengemasan ulang, evaluasi, (2) pelaksanaan pembelajaran Model Investigasi Kelompok dapat meningkatkan aktivitas anggota kelompok,  (3) system evaluasi postes dan formatif (4) prestasi belajar siswa meningkat. Pada kelas XI IPA1, jumlah siswa yang mencapai nilai KKM siklus 1 14 (46,67%), siklus II 19 (63,33%) siklus III 23 (76,67)
