Eksplorasi Berpikir Kritis Siswa dalam Aktivitas Collaborative Problem Solving Pada Penerapan Barisan dan Deret 

Exploration of Critical Thinking of Students in Collaborative Problem Solving Activities On The Application of Rows and Sequences 

Berpikir kritis penting dimiliki untuk bersaing di abad ke-21. Penelitian ini bertujuan untuk mengeksplorasi berpikir kritis siswa dalam aktivitas collaborative problem solving pada penerapan barisan dan deret. Pendekatan penelitian ini menggunakan penelitian deskriptif bersifat eksploratif. Subjek terdiri dari siswa kelas XII MIPA 3 di SMAN 1 Balongpanggang dengan satu kelompok terdiri dari dua siswa dengan kriteria pasangan kolaborasi berpikir kritis tinggi dan rendah, sedang dan rendah, serta berpikir kritis tinggi dan sedang. Teknik pengumpulan data yang digunakan yaitu tes berpikir kritis dalam collaborative problem solving dan wawancara yang dianalisis dengan reduksi data, penyajian data dan penyimpulan. Data yang diperoleh akan dianalisis berdasarkan indikator berpikir kritis dalam collaborative problem solving. Hasil dari penelitian ini menunjukkan bahwa berpikir kritis siswa dalam Collaborative problem solving  terkait penerapan barisan dan deret pada pasangan kolaborasi  berpikir kritis tinggi dan rendah dapat melewati indikator identifikasi, analisis dan evaluasi. Sedangkan berpikir kritis siswa dalam Collaborative problem solving  terkait penerapan barisan dan deret pada pasangan kolaborasi  berpikir kritis sedang dan rendah tidak dapat melewati analisis dan evaluasi.

Critical and collaborative thinking are important skills to have to compete in the 21st century. Even though learning is being carried out as a result of the COVID-19 pandemic, critical and collaborative thinking is still important for students. This study aims to explore students' thinking skills in collaborative problem-solving activities in line and series. This research approach uses descriptive exploratory research. The subjects consisted of 3 collaboration groups of class XII SMA with one group of students consisting of two students. The data analysis techniques used were critical tests in collaborative problem solving and interviews which were analyzed qualitatively. The data obtained will be based on indicators of critical thinking in collaborative problem solving. The results of this study indicate that collaborative problem solving in the collaboration of critical and moderate thinking, high and low is executed well, even though it is done automatically. Everyone who thinks critically and critically in problem solving. Meanwhile, the medium and low critical thinking categories can fulfill all stages in mathematical critical thinking in collaborative problem solving
