Abstract

This research is motivated by the importance of understanding the concepts that must be possessed by every student in physics learning. The alternative learning applied is learning using PhET Media Simulation. This study uses an experimental design with a quasi-experimental type with a non-equivalent control design that uses two classes namely the experimental class and the control class. The instrument used in this study was a test instrument in the form of 20 multiple choice tests. The population of this study was all students of class XI IPA MA Al-Inayah Jerang Ilir Cilegon. Samples are taken randomly by group (class). Data from the research results were analyzed statistically. Data came from the value of the pretest, posttest and gain of the experimental and control classes. The results of the study show that: 1) There is an increase in understanding of concepts of students who get learning in Media Simulation PhET. This can be seen from the results of calculations with the average value of N-gain showing that Ho is rejected and Ha is accepted, namely the acquisition of N-gain experimental class is 0.51, while the average value of N-gain dick class is 0.22; 2) Effectiveness of understanding concepts of students who use PhET Media Simulation. this can be seen from the results of calculations with the t-test in the experimental and control classes. then t table = 2.01 and t count = 6.90. Next, compare tcount with t table and get tcount> ttable or 6.90> 2.01.
