Pengaruh Model Problem Based Learning Terintegrasi Literasi Sains Untuk Meningkatkan Keterampilan Berpikir Kritis Peserta Didik  SMA

The Effect Of An Integrated Problem Based Learning Model Science Literacy To Improve Skills Critical Thinking Of High School Students

Peneitian ini bertujuan untuk mengetahui pengaruh model Problem Based Learning terintegrasi literasi sains untuk meningkatkan keterampilan berpikir kritis peserta didik pada materi usaha dan energi. Hasil pada penelitian berupa keterlaksanaan pembelajaran, keterampilan berpikir kritis, dan respon peserta didik. Jenis penelitian yang digunakan quasi eksperimen dengan teknik random sampling. Subjek penelitian ini adalah kelas X SMA Wahid Hasyim menggunakan dua kelas yaitu X.E3 sebagai kelas kontrol dan X.E4 sebagai kelas eksperimen. Instrumen penelitian terdiri dari lembar observasi keterlaksanaan pembelajaran, lembar tes keterampilan berpikir kritis, dan lembar angket respon peserta didik. Hasil penelitian menunjukkan bahwa model Problem Based Learning terintegrasi literasi sains terlaksana sangat baik dengan rata-rata persentase 98,8%. Peningkatan keterampilan berpikir kritis diukur dengan N-Gain diperoleh rata-rata 0,71 yang menujukkan bahwa kelas eksperimen berada pada kategori tinggi dan 0,40 di kelas kontrol berada pada kategori sedang, kemudian rata-rata respon peserta didik di kelas eksperimen memiliki respon positif dari peserta didik sehngga diperoleh rata-rata persentase sebesar 92,2%, hal ini menujukkan bahwa terdapat pengaruh model Problem Based Learning terintegrasi literasi sains untuk meningkatkan keterampilan berpikir kritis.

This research aims to determine the effect of the Problem Based Learning model integrated with scientific literacy to improve students' critical thinking skills on business and energy material. The results of the research include learning implementation, critical thinking skills, and student responses. The type of research used was quasi-experimental with random sampling techniques. The subject of this research was class X of Wahid Hasyim High School used two classes, namely X.E3 as the control class and X.E4 as the experimental class. The research instrument consisted of a learning implementation observation sheet, a critical thinking skills test sheet, and a student response questionnaire sheet. The research results showed that the Problem Based Learning model integrated with scientific literacy was implemented very well with an average percentage of 98.8%. The increase in critical thinking skills measured by N-Gain obtained an average of 0.71 which shows that the experimental class is in the high category and 0.40 in the control class is in the medium category, then the average response of students in the experimental class has a positive response from students so that an average percentage of 92.2% was obtained, this shows that there is an influence of the Problem Based Learning model integrated with scientific literacy to improve critical thinking skills.
