Abstrak

Penelitian ini bertujuan untuk mengetahui pengaruh Cooperative Learning Model terhadap kemampuan siswa dalam menulis teks deskriptif pada siswa kelas X SMK Tamansiswa Sukadamai Tahun Ajaran 2025/2026. Penelitian ini menggunakan metode kuantitatif dengan desain eksperimen yang melibatkan dua kelompok, yaitu kelas eksperimen dan kelas kontrol. Teknik pengumpulan data dilakukan melalui tes menulis berupa pre-test dan post-test. Data dianalisis menggunakan uji normalitas, uji homogenitas, dan rumus uji-t. Hasil penelitian menunjukkan bahwa nilai rata-rata pre-test pada kelas eksperimen sebesar 60, sedangkan kelas kontrol sebesar 53,6. Setelah diberikan perlakuan, nilai rata-rata post-test kelas eksperimen meningkat menjadi 79,8, sedangkan kelas kontrol mencapai 64,6. Hasil uji-t menunjukkan bahwa siswa yang diajar menggunakan Cooperative Learning Model memperoleh hasil yang lebih baik dibandingkan siswa yang diajar menggunakan metode konvensional. Dengan demikian, Ha diterima dan Ho ditolak. Dapat disimpulkan bahwa Cooperative Learning Model memberikan pengaruh signifikan terhadap kemampuan siswa dalam menulis teks deskriptif.

This study aimed to determine the effect of the Cooperative Learning Model on students’ ability in writing descriptive text at Grade X of SMK Tamansiswa Sukadamai in the 2025/2026 Academic Year. This study used a quantitative research method with an experimental design involving two groups, namely the experimental class and the control class. The data collection technique was conducted through writing tests consisting of pre-test and post-test. The data were analyzed by using normality test, homogeneity test, and t-test formula. The findings showed that the mean score of the pre-test in the experimental class was 60, while the control class was 53.6. After the treatment, the post-test mean score of the experimental class increased to 79.8, whereas the control class reached 64.6. The result of the t-test indicated that the students taught by using the Cooperative Learning Model achieved better scores than those taught by using the conventional method. Therefore, Ha was accepted and Ho was rejected. It can be concluded that the Cooperative Learning Model significantly affects students’ ability in writing descriptive text.
