Penerapan Model Collaborative Learning Untuk Meningkatkan Keterampilan Komunikasi Ilmiah Siswa SMP Pada Materi Sistem Ekskresi Manusia

Aplication of Collaborative Learning Model to Improve the Scientific Communication Skills of Junior High School Student on Human Excretion System Material.

Penelitian ini bertujuan mendeskripsikan keterlaksanaan pembelajaran, peningkatan keterampilan komunikasi ilmiah siswa, dan respons siswa terhadap penerapan model collaborative learning. Desain penelitian ini menggunakan pre-experimental design dengan rancangan penelitian one group pretest posttest design. Penelitian ini dilaksanakan pada semester genap tahun ajaran 2024/2025 di SMPN 1 Bagor, Nganjuk, dengan dengan subjek siswa kelas VIII-D. Instrumen penelitian yang digunakan meliputi lembar observasi keterlaksanaan pembelajaran, soal tes, dan angket respon. Teknik pengumpulan data yang digunakan adalah teknik tes (pretest-posttest), observasi, dan angket. Hasil penelitian diketahui bahwa keterlaksanaan pembelajaran sangat baik dengan rata-rata skor keterlaksanaan 3,95 yang memiliki persentase 98%. Keterampilan komunikasi ilmiah siswa menunjukkan peningkatan yang dibuktikan dengan skor N-Gain sebesar 0,52 (kategori sedang) dan hasil uji-t signifikan (α < 0,05). Selain itu, siswa memberikan respons yang sangat positif terhadap pembelajaran, dengan persentase rata-rata sebesar 83%. Kesimpulan dari penelitian ini adalah penerapan model pembelajaran kolaboratif dapat meningkatkan keterampilan komunikasi ilmiah siswa pada materi sistem ekskresi manusia.

The purpose of this study was to describe the implementation of learning, improvement of students' scientific communication skills, and students' responses to the application of collaborative learning models. This research design used pre-experimental design with one group pretest posttest design. This research was conducted in the second semester of the 2024/2025 academic year at SMP Negeri 1 Bagor, Nganjuk, with class VIII-D students as the research subjects. The research instruments in this study were learning implementation observation sheets, test questionnaires, and response questionnaires. The data collection techniques used were test (pretest-posttest), observation, and questionnaire. Data on the improvement of students' scientific communication skills were analyzed using paired t-test and N-Gain analysis. The results showed that the implementation of learning was very good with an average implementation score of 3.95 which has a percentage of 98%. Students' scientific communication skills showed an increase as evidenced by the N-Gain score of 0.52 (medium category) and significant t-test results (α < 0.05). In addition, students gave a very positive response to learning, with an average percentage of 83%. The conclusion of this study is that the application of collaborative learning models can improve students' scientific communication skills on the topic of human excretory system.
