Pengaruh Model Guided Discovery Learning Berbantuan Media Simulasi PhET Terhadap Pemahaman Konsep Fisika Siswa

Abstract

Tujuan penelitian ini ialah untuk menganalisis pengaruh model guided discovery learning berbantuan media simulasi PhET terhadap pemahaman konsep fisika siswa. Metode penelitian yang digunakan ialah kuasi eksperimen dengan desain the matching only post-test control group design. Populasi dalam penelitian ini yaitu seluruh siswa kelas XI IPA SMA Negeri 22 Palembang yang terdiri dari 6 kelas. Pengambilan sampel dilakukan dengan teknik purposive sampling, dan mengambil 2 kelas sebagai kelas eksperimen dan kelas kontrol. Pengumpulan data menggunakan instrumen tes pemahaman konsep Hasil penelitian menunjukkan bahwa rerata pemahaman konsep kelas eksperimen = 85,00 dan kelas kontrol sebesar   = 71,92. Hasil uji-t berpasangan diperoleh    >  yaitu 8,17 > 1,67; yang berarti ada pengaruh secara signifikan penerapan model guided discovery learning terhadap pemahaman konsep fisika siswa. Diperoleh simpulan bahwa model guided discovery learning berbantuan media simulasi PhET secara signifikan berpengaruh terhadap pemahaman konsep fisika siswa dibandingkan dengan pembelajaran konvensional.       The purpose of this study was to analyze the effect of guided discovery learning models assisted by media PhET simulation of the understanding of students' physics concepts. The research method used was quasi-experimental with the matching only post-test control group design. The population in this study was all students of class XI IPA SMA Negeri 22 Palembang consisting of 6 classes. Sampling was done by purposive sampling technique and took two classes as the experimental class and the control class. Data collection using concept understanding test instruments. The results showed that the mean understanding of the experimental class concept = 85.00 and the control class = 71.92. The results of the t-test are obtained t_count> t_table that is 8,17> 1,67; which means that there is a significant effect of the application of the guided discovery learning model to the understanding of students' physics concepts. It was concluded that the guided discovery learning model assisted by PhET simulation media significantly influenced the understanding of students' physics concepts compared to conventional learning.
