Abstract

This study examined the effect of PhET-assisted problem-based learning on students’ problem-solving ability in momentum and impulse. A quasi-experimental method with a pretest-posttest control group design was used. The participants were 57 eleventh-grade students at SMAN 1 Lembar, consisting of 29 students in the experimental class and 28 students in the control class. The experimental class learned through problem-based learning assisted by PhET simulations, whereas the control class received conventional instruction. Data were collected using six validated and reliable essay items measuring four indicators of problem-solving ability: recognizing the problem, planning a strategy, applying the strategy, and evaluating the solution. The results showed that the experimental class achieved a higher posttest mean score (86.11) than the control class (78.17). The independent-samples t-test indicated a significant difference between groups, t(55) = 2.13, p = .038, confirming the effect of the intervention. The N-Gain score of the experimental class was 0.81, categorized as high, while the control class obtained 0.70, categorized as medium. Indicator-based analysis showed that the highest improvement occurred in planning a strategy, whereas evaluating the solution remained the weakest indicator. These findings suggest that PhET-assisted problem-based learning effectively improves students’ problem-solving ability in momentum and impulse.

Abstract

Materi elastisitas dan hukum Hooke merupakan materi penting untuk pembelajaran fisika sekolah menengah. Materi ini menggabungkan konsep fisika yang berkaitan dengan sifat elastis suatu benda dan hubungannya dengan gaya yang diterapkan padanya. Kemampuan berpikir kreatif siswa sangat penting dalam menunjang proses pembelajaran terkhususnya dalam pembelajaran fisika materi Elastisitas dan Hukum Hooke. Dalam penelitian ini, dilakukan analisis kemampuan berpikir kreatif siswa dalam menyelesaikan soal tes uraian dalam pembelajaran fisika khususnya materi Elastisitas dan hukum Hooke di kelas XI SMAN 1 Labuapi. Penelitian ini menggunakan metode analisis deskriptif kuantitatif dengan Analisis deskriptif kuantitatif dalam penelitian ini berupa hasil persentase masing-masing tingkat kemampuan berpikir kreatif. pengumpulan data melalui observasi dan data yang diperoleh berupa data kuantitatif yang dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa kemampuan berpikir kreatif siswa dalam menyelesaikan maslah-masalah fisika materi Elastisitas dan Hukum Hooke siswa kelas XI SMAN 1 Labuapi yang dominan adalah termasuk dalam kategori sedang. Persentase dari karakteristik kemampuan berpikir kreatif yang tertinggi adalah berpikir Fluency dan yang terendah adalah berpikir Luwes.
