ABSTRAK Telah dilakukan penelitian yang berjudul “Penerapan Model Pembelajaran Kooperatif Tipe Cooperative Integrated Reading Composition (CIRC) Pada Materi Reaksi Redoks untuk Meningkatkan Hasil Belajar Siswa Di Kelas X MIA 1 SMA Negeri 1 Krueng Barona Jaya” yang bertujuan untuk mengetahui hasil belajar siswa, tanggapan siswa, dan aktivitas siswa terhadap model CIRC. Penelitian ini menggunakan pendekatan kualitatif dengan jenis penelitian deskriptif. Subjek penelitian ini yaitu siswa kelas X MIA I yang berjumlah 21 siswa. Instrumen yang digunakan pada penelitian ini berupa lembar lembar observasi, angket tanggapan siswa, dan lembar soal. Data yang diperoleh diolah dengan rumus persentase. Hasil observasi pertemuan pertama sebesar 79,90% dan pertemuan kedua sebesar 95,5%. Hasil penelitian menunjukkan bahwa hasil belajar siswa sebesar 76,19%. Hasil tanggapan siswa terhadap penerapan model CIRC pada materi reaksi redoks, siswa yang memberi respon positif sebesar 82,14% sedangkan siswa yang memberi tanggapan negatif sebesar 17,86%. Berdasarkan hasil penelitian ini dapat disimpulkan bahwa penerapan model CIRC pada materi reaksi redoks dapat meningkatkan hasil belajar dan aktivitas siswa. Kata Kunci: model CIRC, hasil belajar, dan reaksi redoks. ABSTRACT Has conducted a study entitled "Application of Cooperative Learning Model Cooperative Integrated Reading Composition (CIRC) to Content Redox Reactions to Improve Student Results In Class X MIA 1 SMA Negeri 1 Krueng Barona Jaya" which aims to determine student learning outcomes, student, and student activity against the model CIRC. This study used a qualitative approach with descriptive research. Subjects of this study are students of class X MIA I, which has 21 students. The instrument used in this study of observation sheet sheet, questionnaire responses of students, and a booklet. The data obtained were processed by percentage formula. The results of the observation of the first meeting and the second meeting 79.90% of 95.5%. The results showed that the students' learning achievement of 76.19%. The results of students' responses to the application of the model on the material CIRC redox reactions, the students who gave a positive response by 82.14% while the students gave a negative response by 17.86%. Based on these results it can be concluded that the application of the model CIRC on the material of redox reactions can improve learning outcomes and student activity. Keywords: CIRC models, learning outcomes, and redox reactions.
