Keefektifan Pembelajaran Fisika dengan Model Inkuiri Terbimbing Berbantuan PhET Intercative Simutations untuk Meningkatkan Kemampuan Berfikir Kritis Siswa SMA 

The Effectiveness of Learning Physics with the Guided Inquiry Model Aided by PhET Intercative Simutations to Improve Critical Thingking Skills for High School Students

Ketrampilan yang wajib dimiliki oleh peserta didik diabad 21 adalah ketrampilan berpikir kritis. Tujuan penelitian untuk mendeskripsikan keefektifan pembelajaran fisika dengan model inkuiri terbimbing berbantuan PhET Intercative Simutations dalam meningkatkan kemampuan berpikir kritis siswa. Jenis penelitian ini  Pre-Experimental menggunakan  desain one-group pretest-posttest design. Subjek penelitian  XI Mia 5 dan XI Mia 6  SMA  Negeri 2 Magetan berjumlah 36 dan 35 siswa. Siswa sebelum pembelajaran diberikan tes awal dan di akhir pembelajaran diberikan tes akhir dengan materi yang sama. Kemudian data  dianalisis menggunakan uji normalitas, homogenitas, uji t-independent, uji t-berpasangan, dan perhitungan n-gain dengan  IBM SPSS Statistic 23. Penelitian ini menginformasikan  bahwa : a) terdapat peningkatan skor yang signifikan setelah diberikan pembelajaran fisika dengan model inkuiri terbimbing b) tidak terdapat perbedaan n-gain pada kedua kelas c) rerata n-gain  berkategori tinggi. Model inkuiri terbimbing berbantuan PhET Intercative Simutations efektif meningkatkan kemampuan berpikir kritis siswa. Dengan ini,  model inkuiri terbimbing berbantuan PhET Intercative Simutations dapat dijadikan masukan bagi guru untuk meningkatkan kemampuan berpikir kritis siswa.

The skills that must be possessed by students in the 21st century are critical thinking skills. The purpose of the study was to describe the effectiveness of learning physics with a guided inquiry model assisted by PhET Intercative Simutations in improving students' critical thinking skills. This type of research is pre-experimental using a one-group pretest-posttest design. The research subjects XI Mia 5 and XI Mia 6 SMA Negeri 2 Magetan amounted to 36 and 35 students, respectively. Students before learning are given an initial test and at the end of the lesson they are given a final test with the same material. Then the data were analyzed using normality, homogeneity, independent t-test, paired t-test, and n-gain calculations with IBM SPSS Statistic 23. This study informs that: a) there is a significant increase in scores after being given physics learning with a guided inquiry model b) there is no difference in n-gain in the two classes c) the mean n-gain is in the high category. The guided inquiry model assisted by PhET Intercative Simutations is effective in improving students' critical thinking skills. With this, the guided inquiry model assisted by PhET Intercative Simutations can be used as input for teachers to improve students' critical thinking skills.
