PENERAPAN MODEL PEMBELAJARAN KOOPERATIF TIPE TWO-STAY TWO-STRAY (TSTS) UNTUK MELATIH KEMAMPUAN BERPIKIR KRITIS SISWA KELAS X PADA MATERI EKOSISTEM

IMPLEMENTATION OF THE TWO-STAY TWO-STRAY (TSTS) COOPERATIVE LEARNING MODEL TO TRAIN CRITICAL THINKING ABILITY IN CLASS X STUDENTS IN ECOSYSTEM MATERIALS

Tuntutan keterampilan 4C pada abad ke-21 salah satunya adalah keterampilan critical thinking and problem solving. Kemampuan berpikir kritis merupakan kemampuan kognitif untuk menetapkan suatu keputusan atau kesimpulan berdasarkan alasan yang logis dan bukti empiris. Materi ekosistem merupakan materi dengan cakupan yang sangat luas sehingga diperlukan suatu model pembelajaran yang berpusat pada siswa. Model pembelajaraan kooperatif tipe two- stay two-stray merupakan salah satu model pembelajaran kooperatif yang melatih siswa untuk berpikir kritis dengan saling membantu memecahkan masalah dan berpartisipasi baik di dalam kelompoknya maupun di kelompok lain. Tujuan penelitian ini adalah mendeskripsikan korelasi antara kegiatan pembelajaran kooperatif TSTS dengan kemampuan berpikir kritis siswa, aktivitas siswa selama pembelajaran, dan respons siswa setelah melakukan kegiatan pembelajaran. Jenis penelitian yang digunakan adalah penelitian deskriptif kuantitatif dengan desain one group pre-test and post-test design. Sampel pada penelitian ini yaitu 72 siswa kelas X SMAN 1 Driyorejo yang dilaksanakan pada bulan Maret – April 2023. Analisis data menggunakan uji korelasi Spearman. Hasil penelitian menunjukkan bahwa rata-rata gain-score dalam kategori tinggi sebesar 0,78, hubungan model pembelajaran TSTS dengan kemampuan berpikir kritis siswa berkorelasi secara positif sebesar 0,251, keterlaksanaan pembelajaran di kelas sebesar 95,09% dengan kategori sangat baik, dan respons siswa menunjukan kategori sangat baik sebesar 93,18%.

One of the demands for 4C skills in the 21st century is critical thinking and problem solving skills. Critical thinking ability is a cognitive ability to determine a decision or conclusion based on logical reasons and empirical evidence. Ecosystem material is material with a very broad scope so that a student-centered learning model is needed. The two-stay two-stray type of cooperative learning model is a cooperative learning model that trains students to think critically by helping each other solve problems and participate both within their group and in other groups. The purpose of this study was to describe the correlation between TSTS cooperative learning activities and students' critical thinking skills, student activities during learning, and student responses after carrying out learning activities. The type of research used is descriptive quantitative research with a one group pre-test and post- test design. The sample in this study was 72 class X students of SMAN 1 Driyorejo which was held in March - April 2023. Data analysis used the Spearman correlation test. The results showed that the average gain-score in the high category was 0.78, the relationship between the TSTS learning model and students' critical thinking skills was positively correlated by 0.251, the implementation of learning in class was 95.09% in the very good category, and the student's response showed a very good category of 93.18%.
