Penerapan Model Guided Inquiry Learning dengan Media PhET Simulasi Untuk Meningkatkan Keterampilan Proses Sains Peserta Didik SMP

Application of the Guided Inquiry Learning Model with PhET Simulation Media to Improve Science Process Skills of Junior High School Students

Penelitian ini untuk mendeskripsikan keterlaksanaan pembelajaran model guided inquiry dengan media PhET, peningkatan KPS peserta didik SMP dan respon peserta didik terkait proses pembelajaran yang berlangsung. Aspek KPS yang diteliti yaitu merumuskan masalah, membuat hipotesis, mengidentifikasi variabel, menginterpretasi data, dan membuat kesimpulan. Penelitian ini deskriptif dengan desain penelitian one group pretest posttest. Subjek penelitian yaitu peserta didik SMP Negeri 18 Surabaya kelas VIII-I. Hasil penelitian menunjukkan hasil modus keterlaksanaan pembelajaran dari 3 pengamat yaitu sebesar 4 dengan kategori sangat baik. Peningkatan KPS ditunjukkan berdasarkan hasil paired T-test diperoleh sig. 0,000 < 0,05 maka  ditolak menunjukkan bahwa terdapat perbedaan signifikan antara pretest dan posttest. Berdasarkan effect size, diperoleh besar efek yaitu 0,97 adanya efek perbedaan sangat substansial antara pretest dan posttest. Respon peserta didik terkait guided inquiry dengan media PhET yaitu minat sebesar 98%, keaktifan sebesar 85%, kemudahan pemahaman 89%, dan KPS sebesar 88%. Berdasarkan hasil penelitian tersebut, dapat disimpulkan bahwa penerapan model guided inquiry dengan media PhET berpengaruh secara signifikan terhadap KPS dan dapat meningkatkan KPS peserta didik SMP. 

This research is to describe the implementation of the guided inquiry learning model with PhET media, the improvement of the SPS of junior high school students and the responses of students related to the ongoing learning process. The SPS aspects studied were formulating problems, making hypotheses, identifying variables, interpreting data, and making conclusions. This research is descriptive with a one group pretest posttest research design. The research subjects were class VIII-I students of SMP Negeri 18 Surabaya. The results of the learning implementation mode from 3 observers were 4 in the very good category. The increase in SPS was shown based on the results of the paired t-test obtained by sig. 0.000 <0.05 then  is rejected indicating that there is a significant difference between pretest and posttest. Based on the effect size, a large effect was obtained, namely 0.97, with a very large effect difference between the pretest and posttest. Student responses related to guided inquiry with PhET media, namely interest by 98%, activity by 85%, ease of understanding 89%, and SPS by 88%. Based on the results of this study, it can be interpreted that the application of the guided inquiry model with PhET media has a significant effect on SPS and can increase the SPS of junior high school students.
