Penerapan Model Problem Based Learning Berbantuan Virtual Lab Pada Pembelajaran Fisika Untuk Meningkatkan Kemampuan Literasi Sains Peserta didik SMA kelas X

Application of the Problem Based Learning Model Assisted by Virtual Lab in Physics Learning to Improve the Scientific Literacy Skills of Class X Hingh School Students

Penelitian ini bertujuan untuk mendeskripsikan peningkatan dan pengaruh kemampuan literasi sains  setelah diberikan pembelajaran model problem based learning berbantuan virtual lab (PhET Simulations) serta respon peserta didik setelah diterapkan problem based learning berbantuan virtual lab (PhET Simulation) pada materi efek rumah kaca terhadap kemampuan literasi sains  peserta didik di kelas X SMA Negeri 1 Bondowoso. Desain penelitian yang digunakan yakni nonequivalent-control group design. Instrumen penelitian yang digunakan lembar tes kemampuan literasi sains dan lembar angket respon peserta didik. Data kemampuan literasi sains peserta didik dianalisis menggunakan uji t-independent, analisis n-gain, dan uji regresi linear sederhana. Data respon peserta didik dianalisis menggunakan Skala Likert dalam bentuk persentase. Dalam pengujian menggunakan pretest dan posttest ini menggunakan aspek kompetensi yang terdiri dari 3 aspek diantaranya menjelaskan fenomena secara ilmiah, mengevaluasi dan merancang penyelidikan secara ilmiah, serta menafsirkan data dan bukti secara ilmiah, kemampuan literasi sains pada setiap kompetensi mengalami peningkatan. Kompetensi yang mengalami kenaikan paling tinggi pada kompetensi 1 ditunjukkan dengan persentase pada pretest didapatkan 26,95 dan 25,58 sedangkan pada posttest  didapatkan 72,96 dan 53,18. Kompetensi yang mengalami kenaikan paling rendah pada kompetensi 3 ditunjukkan dengan persentase pada pretest didapatkan 25,86 dan 24,32 sedangkan pada posttest  didapatkan 67,38 dan 36,77. Kemampuan literasi sains peserta didik meningkat pada kelas eksperimen dengan rata-rata n-gain sebesar 0,718 berkategori tinggi sedangkan pada kelas kontrol sebesar 0,409 berkategori sedang. Model pembelajaran problem based learning berbantuan virtual lab (PhET Simulations) memiliki pengaruh terhadap kemampuan literasi sains yang diujikan menggunakan uji regresi linear sederhana sebesar 22,20%. Respon peserta didik terhadap penerapan model pembelajaran problem based learning berbantuan virtual lab (PhET Simulations) diperoleh sebesar 71% berkategori baik. Berdasarkan hasil penelitian yang telah dilakukan disimpulkan bahwa penerapan model problem based learning berbantuan virtual lab pada pembelajaran fisika dapat meningkatkan kemampuan literasi sains peserta didik SMA kelas X.

This study aims to describe the increase and influence of scientific literacy skills after being given a virtual lab-assisted problem-based learning model (PhET Simulations) and student responses after applying virtual lab-assisted problem-based learning (PhET Simulation) to the greenhouse effect material on scientific literacy skills. students in class X SMA Negeri 1 Bondowoso. The research design used is the nonequivalent-control group design. The research instrument used was a scientific literacy ability test sheet and a student response questionnaire sheet. Data on students' scientific literacy abilities were analyzed using the independent t-test, n-gain analysis, and simple linear regression tests. Student response data were analyzed using a Likert Scale in the form of a percentage. In testing using the pretest and posttest using competency aspects which consist of 3 aspects including explaining phenomena scientifically, evaluating and designing scientific investigations, and interpreting data and evidence scientifically, scientific literacy skills in each competency have increased. The competency that experienced the highest increase in competency 1 was shown by the percentage in the pretest obtained 26.95 and 25.58 while in the posttest obtained 72.96 and 53.18. The competency that experienced the lowest increase was in competency 3 as indicated by the percentage in the pretest obtained 25.86 and 24.32 while in the posttest obtained 67.38 and 36.77. The ability of students' scientific literacy increased in the experimental class with an average n-gain of 0.718 in the high category while in the control class it was 0.409 in the medium category. The virtual lab-assisted problem-based learning model (PhET Simulations) has an influence on scientific literacy skills tested using a simple linear regression test of 22.20%. Student responses to the application of the problem-based learning model assisted by virtual labs (PhET Simulations) were obtained by 71% in the good category. Based on the results of the research that has been done, it is concluded that the application of the virtual lab-assisted problem-based learning model in physics learning can improve the scientific literacy skills of class X high school students.
