Abstract

Penelitian ini bertujuan untuk menerapkan model PBL berbasis daring untuk meningkatkan kemampuan berpikir kritis peserta didik kelas XI MIPA 3 SMA Negeri 77 Jakarta materi program linear dan matriks. Berdasarkan hasil observasi, wawancara terhadap guru serta tes awal kemampuan berpikir kritis di kelas tersebut terlihat bahwa kemampuan berpikir kritis yang dimiliki peserta didik masih rendah, sehingga perlu ditingkatkan. Penelitian ini merupakan Penelitian Tindakan Kelas (PTK) yang dilaksanakan dalam tiga siklus dengan subjek penelitian sebanyak enam orang yang mewakili peserta didik dengan kemampuan tinggi, sedang dan rendah berdasarkan hasil tes kemampuan awal. Hasil penelitian menunjukan bahwa pembelajaran matematika pada materi program linear dan matriks dengan menerapkan model PBL berbasis daring dapat meningkatkan kemampuan berpikir kritis peserta didik melalui proses diskusi dalam menyelesaian masalah yang disajikan dalam lembar kerja. Peningkatan kemampuan berpikir kritis juga dapat ditunjukan dengan meningkatnya nilai rata-rata yang diperoleh pada tes kemampuan awal sebesar 23, rata-rata tes akhir siklus I sebesar 76, rata-rata tes akhir siklus II sebesar 78,4, dan rata-rata tes akhir siklus III sebesar 87,03. Selain itu, persentase peserta didik yang memperoleh nilai pada kategori minimal baik sejak pelaksanaan tes kemampuan awal berpikir kritis sebesar 2,5%, tes akhir siklus I sebesar 72,5%, tes akhir siklus II sebesar 82,5%, dan tes akhir sikus III sebesar 90%. *********** This research aims to apply an online problem based learning model to improve Students critical thinking skills in class XI MIPA 3 SMAN 77 Jakarta with linear program and matrix materials. Based on the results of observations, interviews with teachers and initial ability tests of critical thinking skills in the class, it can be seen that the critical thinking skills of students are still low, so it needs to be improved. This research is a Classroom Action Research (CAR) which was carried out in three cycles with six research subjects representing students with high, medium and low abilities based on the results of the initial ability test. The results showed that learning mathematics in linear program and matrix materials by applying online problem based learning model could improve students' critical thinking skills through a discussion process in solving problems presented in worksheets. The increase in critical thinking skills can also be shown by increasing the average score obtained in the initial ability test by 23, the average final test in the first cycle of 76, the average final test in the second cycle of 78.4, and the average final test cycle III of 87.03. In addition, the percentage of students who scored in the minimally good category since the implementation of the initial critical thinking ability test was 2.5%, the final test of the first cycle was 72.5%, the final test of the second cycle was 82.5%, and the final test of the cycle. III by 90%.
