Pengaruh Model Pembelajaran Problem Based Learning Berbantuan Phet Terhadap Keterampilan Berpikir Kreatif Siswa Siswa SMA Materi Gravitasi Dan Obit

This study aims to determine the effect of the problem based learning model assisted by PhET on students' creative thinking skills on gravity and orbit material in class XI students. This research is a quasi-experimental research with PostTest Only design. The population of this study were all students of class XI totaling 62 people. With purposive sampling technique, the sample in this study was class XI IPA 1, which was 30 people for the experimental class and class XI IPA 2, which was 32 people for the control class. The data collection instrument used a test. The data analysis techniques used are validity test, reliability test, normality test, homogeneity test, and hypothesis testing. Based on the results of the final test, the average experimental class was 91 and the control class was 71. The data obtained were analyzed using the t-test. Based on the results of calculations and data analysis on students' conceptual understanding, it shows that the t-count obtained is 1.850 while the t-table price at a significance level of 5% is 2,000 (t-count < t-table). So it can be concluded that in this study Ho is accepted and Ha is rejected, that there is no influence of PhET on gravity and orbit material on the creative thinking skills of class XI students.
