Pengembangan WEB-FIST (Web Fisika Berbasis STEM) untuk Melatih Critical Thinking siswa pada Topik Gerak Parabola

Development of WEB-FIST (STEM-Based Physics Web) to Train Students' Critical Thinking on the Topic of Parabolic Motion

Penelitian ini bertujuan untuk mendeskripsikan kelayakan media Web-FIST ditinjau dari validitas dan efektivitasnya. penggunaan Web-FIST untuk melatih berpikir kritis siswa pada topik gerak parabola. Penelitian ini menggunakan model desain penelitian Hannafin & Peck. Teknik pengumpulan data yang digunakan adalah validitas instrumen, pretest-posttest berupa essay, dan angket respon dengan subjek 13 siswa kelas X MIPA SMA di Tuban. Validitas ditinjau berdasarkan kesesuaian aspek-aspek berikut: 1) sistem web, 2) kebenaran isi materi, 3) pendekatan STEM, 4) karakteristik berpikir kritis, 5) materi dengan sifat fisika, dan 6) standar kompetensi. Sedangkan keefektifan ditinjau dari hasil observasi berpikir kritis dan respon siswa. Validasi media dilakukan oleh dua orang ahli media. Berdasarkan analisis data yang telah dilakukan, diperoleh hasil validitas Web-FIST sebesar 92,83% dengan klasifikasi sangat valid (92,83%). Hasil efektivitas penggunaan Web-FIST diperoleh N-Gain sebesar 0,6 dengan klasifikasi sedang, sedangkan dari penilaian respon siswa diperoleh nilai rata-rata 86% dengan klasifikasi sangat efektif. Berdasarkan hasil analisis data, dapat disimpulkan bahwa Web-FIST yang dikembangkan layak digunakan dalam proses pembelajaran dan dapat melatih berpikir kritis siswa tentang gerak parabola.

This research aims to describe the feasibility of Web-FIST media in terms of validity and effectiveness. the use of Web-FIST to practice students' critical thinking on the topic of parabolic motion. This study uses a research design model of Hannafin & Peck. The data collection technique used was the validity instrument, the pretest-posttest in the form of an essay, and the response questionnaire with the subject of 13 students of class X Mathematics and Natural Sciences in Senior High School in Tuban. The validity is reviewed based on the suitability of the following aspects:1) the web system, 2) the correctness of the content of the material, 3) the STEM approach, 4) critical thinking characteristics, 5) the material with the nature of physics, and 6) competency standards. While the effectiveness in terms of the results of critical thinking observations and student responses. Media validation was carried out by two media experts. Based on the data analysis that has been carried out, the results of the Web-FIST validity are 92.83% with a very valid classification (92.83%). The results of the effectiveness of using Web-FIST obtained an N-Gain of 0.6 with a moderate classification, while from the assessment of student responses an average value of 86% was obtained with a very effective classification. Based on the results of the data analysis, it can be concluded that the developed Web-FIST is suitable for use in the learning process and can train students' critical thinking about parabolic motion.
