Abstract

Keterampilan berpikir kritis merupakan keterampilan yang sangat penting dimiliki oleh peserta didik saat ini. Namun dilihat dari fakta yang ada, keterampilan berpikir kritis peserta didik di SMA masih banyak yang rendah. Dari hasil data yang telah dikumpulkan mengenai kemampuan berpikir kritis peserta didik yang masih rendah mengenai pembelajaran fisika tentunya dipengaruhi oleh minat yang dimiliki oleh setiap kelompok peserta didik. Penelitian ini bertujuan untuk meningkatkan keterampilan berpikir kritis peserta didik di salah satu SMA pada kelas 10 di salah satu SMA Negeri di Sukabumi. Penelitian ini menggunakan metode kuantitatif dengan desain one-group pretest-posttest. Partisipan 36 peserta didik dipilih dengan menggunakan teknik purposive sampling. Instrumen kemampuan berpikir kritis materi pemanasan global berbentuk pilihan ganda, lembar kerja peserta didik, dan lembar observasi keterlaksanaan model pembelajaran. Lembar observasi keterlaksanaan pembelajaran dianalisis melalui persentase rata-rata tiap tahapan pembelajaran dan peningkatan keterampilan berpikir kritis dianalisis menggunakan N-Gain. Hasil penelitian menunjukkan bahwa keterlaksanaan model pembelajaran problem based learning dengan pendekatan diferensiasi produk sangat baik dengan rata-rata 100% dan keterampilan berpikir kritis peserta didik meningkat dengan nilai rata-rata N-Gain 0,42 termasuk dalam kategori sedang. Dengan demikian, model pembelajaran problem based learning dengan pendekatan diferensiasi produk dapat meningkatkan keterampilan berpikir kritis peserta didik pada materi pemanasan global. Critical thinking skills are very important skills for students today. However, judging from the facts, the critical thinking skills of students in high school are still low. From the results of the data that has been collected regarding the critical thinking skills of students who are still low regarding physics learning, of course, it is influenced by the interests possessed by each group of students. This study aims to improve the critical thinking skills of students in one of the high schools in grade 10 in one of the public high schools in Sukabumi. This study uses a quantitative method with a one-group pretest-posttest design. Participants were 36 students selected using purposive sampling technique. Instruments for critical thinking skills on global warming material were in the form of multiple choice, student worksheets, and observation sheets for the implementation of the learning model. The learning implementation observation sheet was analyzed through the average percentage of each learning stage and the improvement of critical thinking skills was analyzed using N-Gain. The results showed that the implementation of the problem base learning model with a product differentiation approach was very good with an average of 100% and students' critical thinking skills increased with an average N-Gain value of 0.42 including in the moderate category. Thus, the problem base learning model with a product differentiation approach can improve students' critical thinking skills on global warming material.
