Abstract
The purpose of this research is to find out the High Order Thinking Skills (HOTS) ability of class X students after the application of the problem-based learning model assisted by Powtoon animation media and after the application of conventional learning models, as well as to find out which learning model is more effective in improving student HOTS class X. Research methods used are quantitative with quasi-experiment research design two group pretest-posttest. The population of this study was class X students at SMA Swasta Cerdas Murni, and the samples used were students of class X MIPA 1 as the experimental class and X MIPA 2 as the control class. Data collection was carried out with HOTS questions on the pretest and posttest. The results showed that the average pretest scores in the experimental and control classes were 37.4 and 35.5, respectively, while the average posttest scores obtained in the experimental and control classes were 80.7 and 75.2. The average N-Gain score in the experimental class is 0.70 and belongs to the "high" category, while in the control class, the average N-Gain score is 0.61 and belongs to the "medium" category. This study concludes that there is a better improvement after applying the problem-based learning model assisted by Powtoon animation to students' HOTS abilities so that the problem-based learning model assisted by Powtoon animation is more effective in improving students' HOTS abilities compared to conventional learning models.
