One strategy that can be designed by teachers to be able to improve collaboration and communication skills is by implementing a jigsaw type of cooperative learning model. This study aims to improve students collaboration and communication skills by applying the jigsaw learning model to environmental change material. The research method is descriptive quantitative. The true experimental design of the posttest-only control design was applied to this study. Analysis with t-test. The results of the average score obtained by the ability of collaboration in the experimental class 81 and the results of the average value of 89 communication skills are included in the very effective category. Based on the results of the study it can be concluded that the jigsaw type cooperative learning model can improve students collaboration and communication skills on environmental change.

Penelitian ini bertujuan meningkatkan kemampuan kolaborasi dan komunikasi siswa dengan menerapkan model pembelajaran jigsaw pada materi perubahan lingkungan. Metode penelitian adalah deskriptif kuantitatif. Desain true eksperimen jenis posttest-only control design diterapkan pada penelitian ini. Analisis dengan uji t-test. Hasil nilai rata-rata yang diperoleh kemampuan kolaborasi pada kelas eksperimen 81 dan hasil nilai rata-rata kemampuan komunikasi 89 termasuk kategori sangat efektif. Berdasarkan hasil penelitian dapat disimpulkan bahwa model pembelajaran kooperatif tipe jigsaw dapat meningkatkan kemampuan kolaborasi dan komunikasi siswa pada materi perubahan lingkungan.
